Automotive plastics and rubber play a crucial role in the innovations for all types of automobiles and in a wide spectrum of applications, including the interior, exterior, under-bonnet, and others. Technological advancement in the materials further boosts the development of the automotive industry beyond the conventional realm.Owing to their advantages of lightweight, ease of processing, design flexibility, and possible sourcing from sustainable raw materials, high-end plastics and rubber are increasingly used to replace metals in automotive components, without compromising on performance and safety.The latest examples of automotive plastics and rubber applications reveal how the rapid development of the materials is driving the mobility forward.PA6 enclosure for high-voltage EV batteryTechnical plastics such as polyamide 6 (PA6) offer numerous benefits for the design of battery enclosures for electric vehicles (EVs), such as sustainability, manufacturing costs, weight savings and economical functional integration.To prove such plastic enclosures can meet the very demanding mechanical and flame-retardant requirements, Kautex Textron and LANXESS carried out a comprehensive examination using a jointly developed technology demonstrator made from PA6.The results showed that the near-series demonstrator passes all relevant mechanical and thermal tests. An enclosure prototype has been being road tested in a test vehicle to verify its suitability for daily use. The companies are currently jointly tackling the first series-production development projects with automotive manufacturers.The large-format all-plastic enclosure, which measures around 1,400 millimeters in both length and width, meets the requirements of the mechanical shock test and crush test. The results of the drop and vibration tests were also positive, as were those of the bottom impact test.The demonstrator also proved its resistance to external sources of fire underneath the vehicle in accordance with ECE R100 (external fire).Besides, calculations revealed that the carbon footprint of the plastic enclosure is over 40% smaller compared to an aluminum design.The lower energy use in the production of PA6 compared with metal as well as other factors, such as the omission of time-consuming cathodic dip painting to prevent corrosion where steel is used, help to minimize the carbon footprint.The thermoplastic component design also makes recycling the enclosure easier compared with thermoset materials such as sheet molding compounds (SMC).As explained, the demonstrator was developed based on the aluminum battery housing of a mid-size EV and designed for mass production. It is manufactured in a single-stage compression molding process with a molding compound based on the PA 6 compound Durethan B24CMH2.0 from LANXESS and does not require any further rework.Crash-relevant areas are specially reinforced with locally placed blanks made from the continuous-fiber-reinforced, PA6-based composite Tepex dynalite 102-RGUD600. Compared with an aluminum design, there is a weight saving of around 10%, which is advantageous for the range and therefore the carbon footprint of the vehicle.The integration of functions, such as the fasteners, reinforcing ribs and components for the thermal management, reduces the number of individual components significantly. This simplifies assembly and logistical effort and reduces manufacturing costs. Blow molding monolayer hybrid vehicle fuel tankAs e-mobility continues to leap forward, regulations and standards are evolving alongside the automotive industry. European union regulations set a maximum CO2 emission rate of 95g/km for passenger cars, which necessitates a balance of materials and design to maximize fuel efficiency.DSM Engineering Materials has announced its partnership with Renault to develop an industry-first lightweight solution for hybrid vehicle fuel tanks.By using Akulon Fuel Lock, DSM's high-performance low-carbon-footprint PA6 material, the fuel tanks can be produced with a blow molding monolayer construction that significantly reduces weight and cost without compromising safety or risking additional emissions.Plug-in hybrid vehicles enable the use of smaller fuel tanks, making a polymer solution more viable, but high-density polyethylene (HDPE) still requires multilayer structures with complex additional features to prevent permeation and withstand the extended periods of internal pressure inherent to Plug-in hybrid vehicles.Akulon Fuel Lock PA6 grades are designed for injection or blow molding and extrusion, making them highly versatile for the design innovation of the e-mobility sector. High parison stability enables very narrow wall thickness distribution, and robust performance at both high and low temperatures ensures paramount safety.The materials thereby offer a drop-in solution and a second life to the monolayer blow molding machines dedicated to the production of the declining diesel monolayer fuel tanks.Engineering plastic used in front fenderLG Chem has started supplying LUCON TX5007 engineering plastic to Mitsubishi Motors for its powder coating parts used as the front fenders of the RVR, Delica D:5 and Outlander models.Front fender is located on the side of the vehicle, which not only acts as one of key factors in the exterior design but also protects wheels from road debris. Therefore, it not only should possess high mechanical robustness but also high exterior quality.LUCON TX5007 is a compound material that combines modified polyphenylene ether (mPPE) and polyamide (PA66) alloy with carbon nanotubes (CNTs). It has high electrical conductivity and shows strong mechanical properties.Moreover, the material has high heat resistance, making it suitable for the automotive on-the-line painting process at 200°C or higher. At the same time, it provides high dimensional stability thanks to its low coefficient of linear thermal expansion (CLTE).When a plastic fender is used, the weight of the vehicle is reduced by about 4kg, which also improves fuel efficiency. It can also provide other benefits, such as reduced fuel exhaust emission and carbon footprint.Using CNT in engineering plastics can support diverse requirements. CNT is a filler that provides high conductivity even with a small amount. The material covers a wider range of electrical conductivity compared to other carbon fillers such as carbon black and carbon fiber.Lightweight PC heat-sink for car lightingX2F has teamed up with Covestro to develop a thermally conductive automotive heat-sink with in-mold electronics (IME) using X2F’s transformative controlled viscosity molding technology.This new product molded of Covestro's Makrolon polycarbonate (PC) is approximately half as heavy as the typical aluminum part.It is part of an in-mold assembly that can be used to integrate LED modules directly into the headlamp housing, eliminating the weight and labor associated with the installation of brackets, screws, thermal pastes, and adhesives.According to Covestro, the LED module is attached directly onto the thermally conductive heat-sink without fundamentally changing the heat-sink adjuster module design.The X2F technology is production-ready and has been demonstrated in high-volume series manufacturing for other applications. It enables sensitive electronics to be insert molded, thus providing functional integration, heat management, modularity, and miniaturization.This innovative technology enables the manufacture of previously impossible-to-mold thermoplastic parts. The result is 30-200% improvement in performance depending on the applications and materials used, says X2F.In the case of heat-sink, it dramatically streamlines production, reduces manufacturing times, eliminates fasteners and paste, and increases product design flexibility.X2F’s ability to mold thermally conductive materials has applications far beyond heat-sink. Thermal management is critical for superior performance in battery, motor, and printed circuit board applications.X2F has recently added a rotary table that reduces cycle time and facilitates higher-volume production for its controlled viscosity molding machine. Production volume can reach up to four million parts per year with one unit depending on the cycle time. Bio-attributed PVC for seat upholsteryIndependent Volvo spin-off and high-performance EV manufacturer Polestar has adopted INEOS Inovyn's BIOVYN in the seat upholstery for its new Polestar 3 SUV model.BIOVYN bio-attributed vinyl is made of 100% renewable feedstock that does not compete with the food chain. It replaces fossil based raw materials with renewable materials obtained from crude tall oil, a byproduct of coniferous tree pulping.Having the same properties as conventional polyvinyl chloride (PVC), BIOVYN is billed as the first bio-attributed PVC available for commercial use that enables a carbon footprint reduction of over 70%. It is also the first PVC product certified by the Roundtable on Sustainable Biomaterials.First released in 2019, BIOVYN was designed to meet performance and quality requirement in different industry sectors while moving society closer to a circular and carbon neutral economy.Meanwhile, another INEOS Group company INEOS Styrolution’s Luran S SPF 30 grade has been selected for rear spoiler application in Dolphin model by BYD Auto.Luran S is the acrylonitrile styrene acrylate (ASA) copolymer brand of the company, boasting high weathering, impact and chemical resistance.The company’s portfolio of ASA products can be formulated with enhanced UV stability, such as SPF 30, to further increase protection from UV exposure. Luran S also offers high design flexibility due to its colorability and dimensional stability.In addition, the material provides good surface adhesion, making it possible for car manufacturers to overlay the Luran S substrate with a hot-stamped foil for decorative features on exterior parts.Translucent polyolefin foam for automotive interiorHow people interact with vehicles and how interiors can be optimized are catching more attention in future mobility. Seeing a growing trend towards making surface multifunctional, Sekisui Alveo has developed translucent foam for use in automotive interior.The special foam allows light to pass through soft trim elements such as the dashboard and door panels, displaying information or providing illumination. It drives the trend in automotive interior design, particularly that of EVs.The breakthrough in this new technology is translucent foam. Foams are typically opaque due to their cell structure and various components. However, they can be made translucent.The newly developed foams include the PE foams TL LV and TLA LV, in white and natural. They are suitable for applications with low thermal requirements like door roll and door panel.Thermal requirements are higher for applications above the belt line where polypropylene (PP) foams are required. The European manufacturer of high-quality polyolefin foams is now developing PP foams with greatly improved translucent properties.Bio-based PU system for automotive acoustic applicationsACOUSTIFLEX VEF BIO system is the bio-based viscoelastic foam technology launched by Huntsman for molded acoustic applications in the automotive industry. It contains up to 20% bio-based content derived from vegetable oils.This new solution can lower the carbon footprint of automotive carpet back-foaming by up to 25% compared to existing Huntsman systems for this application. The technology can also be used for dash and wheel arch insulation.There was a concern that incorporating bio-based content into a polyurethane (PU) foam system would have a detrimental impact on performance, specifically on emission and odor levels. The development of ACOUSTIFLEX VEF BIO system proves that doesn’t need to be the case, emphasizes Huntsman.When it comes to acoustic performance, analysis experiments show that original VEF systems can outclass standard high resilient (HR) foams at lower frequencies (<500 Hz). ACOUSTIFLEX VEF BIO system achieves the same magnitude of sound reducing capability.In developing ACOUSTIFLEX VEF BIO system, the company has continued its work in the development of zero-amine, zero-plasticizer, and extremely low aldehyde emitting PU foams. As a result, the system is both low emission and low odor, and remains lightweight as VEF systems.The company's automotive team has also ensured there are no associated processing disadvantages, with high productivity rates and demold times as low as 80s depending on part design.Synthetic rubber solutions to boost NEV developmentIn line with the increasing demands for sustainable mobility, ARLANXEO develops advanced synthetic rubber products and solutions with local innovation capabilities and collaboration across the industry chain.Leveraging the company’s environmentally-friendly Keltan ACE catalyst technology, Keltan Ultra-high Mooney 100+ Innovation Platform is primarily focused on the development of new and sustainable synthetic rubber grades with high Mooney viscosity, to optimize physical properties and cost, for upgraded applications in the automotive, transportation, and other sectors.The platform carries four grades currently. The new grade of Keltan 10675C has better abrasive resistance and elasticity, catering to the needs for customized new energy vehicles (NEVs) parts, such as wiring harness systems.Meanwhile, Keltan 10660C possesses both ultra-high molecular weight and a combination of processing and mechanical properties. It is applied to automobile hoses and railway rubber parts. Keltan 10950C features excellent extrusion performance, offering an alternative for producing high-performance sponge seals for automobiles and buildings.For tire technology, ARLANXEO teamed up with Bridgestone and Solvay to launch TECHSYN, which combines chemically optimized synthetic rubber with tailor-made silica to achieve up to 30% better wear efficiency and up to 6% less rolling resistance. The result is an overall reduction of fuel consumption and CO2 emissions.In addition, the Changzhou Li-ion Battery Lab located in ARLANXEO’s headquarter in China is designed to contribute to developing energy storage solutions for NEVs with customers.The lab was upgraded with a new pouch cell line, thus enables it to fully support research and development of Li-ion battery, including optimizing battery materials to improve battery energy density, exploring solutions in accordance with customer’s production process, enhancing production processes to reduce production costs, etc.                                                                 Demonstration tire made from 90% of sustainable materialsGoodyear has unveiled a demonstration tire comprised of 90% sustainable materials, which has passed all applicable regulatory testing as well as the company’s internal testing.The demonstration tire was also tested to have lower rolling resistance when compared to the reference tire made with traditional materials. Lower rolling resistance represents the potential to offer better fuel savings and carbon footprint reduction.As introduced, 17 featured ingredients across 12 different components are included in the demonstration tire. Four different types of carbon black, which are produced from methane, carbon dioxide, plant-based oil, and end-of-life tire pyrolysis oil feedstocks, are used.The use of soybean oil helps keep the tire’s rubber compound pliable in changing temperatures. High-quality silica produced from rice husk waste residue (RHA silica) is used to help improve grip and reduce fuel consumption.Traditional petroleum-based resins for enhancing tire traction performance are replaced with bio-renewable pine tree resins. The technical grade polyester for tire cords comes from post-consumer bottles recycling. ISCC certified mass balance polymers from bio- and bio-circular feedstocks are also included.Goodyear explained that bringing a 90% sustainable-material tire to market will require further collaboration with its supply base to identify the scale necessary for producing the materials to produce that specific tire at high volumes.Nevertheless, the tire manufacturing company plans to sell a tire with up to 70% sustainable material content in 2023 and introduce a 100% sustainable-material tire by 2030. source : https://www.adsalecprj.com/web/news/article_details?id=61510&lang=1edit : handler

High-Speed All-Electric Machine Line LaunchesKorea’s LS Mtron will introduce the ONE*-E series with five sizes—120, 140, 190, 310, and 390 tons—with plans to introduce four more models later this year.LS Mtron (U.S. offices Peachtree Corners, Ga.) will introduce the ONE*-E line of all-electric injection molding machines at Plastec West (Anaheim, Calif.; April 12-14) in the Hirate America booth. The ONE*-E is a new, all-electric injection molding machine from LS Mtron that features a new toggle-link design for fast, best-in-class speeds (1.49 second dry cycle times). The ONE*-E will launch in the U.S. with five sizes of 120, 140, 190, 310, and 390 tons, with plans to introduce four more models later in 2022. The company says the machines are suited for  high-cavitation, high-speed, and thinwall molding typical in packaging and medical applications. The machines utilize a new optimized toggle for fast cycles and precision molding, according to LS Mtron. Specifically the company says the new toggle design allows a 30% faster link-speed ratio and a dry-cycle time of just 1.49 seconds. In addition, the ONE*-E features an overall smaller footprint compared to existing ONE*-E’s, shrinking from 5453 by 1499 by 1853 mm (approx. 215 by 59 by 74 in.) to 5281 by 1495 by 1800 mm (208 by 59 by 71 in.).Constructed from a rigid, one-piece casting, the ONE*-E offeres reduced vibration while shortening the injection acceleration time for thinwall molding by almost 4 times, according to LS Mtron, from 78 ms to 20 ms. The company says the rigid construction and a low-inertia design also reduced rotator inertia by 74%. The machine’s control features a 18.5-in. touchscreen as standard, with a 21.5-in. option that gives users swipe, pinch and zoom functionality. It also offers users LS Mtron’s CSI monitoring and control software for retrieving and controlling data, using a next-generation dual-core CPU. The CPU structure allows the machine’s control to separate the architecture into main and HMI CPUs. This allows it to improve load times and offer additional modes, including clamp-force optimization mode; clamping high-speed low-vibration profile mode; high-speed injection mode; packing (or holding) pressure pattern selection mode; and residual pressure elimination mode in case of charging completion.In addition to automatic weight control software, the ONE*-E can monitor clamp force via a tie bar sensor to automatically calibrate closing force. There is also an automatic zero-point adjustment mode for a spring mold. The machine’s dual center press die structure minimizes the platen deformation while also better distributing surface pressure in the mold, helping to extend tool life.  Digital load cells improve measurement control and process reproducibility. Specifically, the company says it allows minimized deviation through precise injection pressure and charging control; increased servo motor encoder resolution from 17 bits to 20 bits; enhanced response performance to the drive control frequency by 3.7 times; and faster Ethernet communication by 2 times.The ONE*-E line of all-electric injection molding machines will debut in the U.S. with five tonnages.Source:https://www.ptonline.com/products/high-speed-all-electric-machine-line-launchesEdit : handler

In big shift to EVs, supplier forecasts differGlobal supplier projections on how large the EV market will be over the next decade vary by quite a bit.Las Vegas — As established automakers and industry newcomers talked up new electric models at CES last week, major suppliers for many of those vehicles have significantly different forecasts for how quickly consumers will buy them.Take ZF Group and Magna International Inc., the world's third- and fourth-largest suppliers. ZF anticipates EV production accounting for about 45 percent of global vehicle output by 2030, with EVs representing 49 percent of all vehicles assembled in North America."We see the U.S. certainly catching up globally to the other major markets," said John Hawkins, ZF's vice president of electrified powertrains for North America.Magna, meanwhile, sees EV sales accounting for only about 20 percent of the global market by 2030, with the U.S. coming in below the global average.Magna Chief Technology Officer Anton Mayer told Automotive News that consumer acceptance of EVs might be hindered by each country's charging infrastructure."In Europe, I see a lot of activity in investments in infrastructure," he said. "In the U.S., I see the possibility of the Biden administration, that they want to spend on a lot of things. But I'm still critical about if this will be right in time."Pace of adoptionThe discrepancy between the two suppliers' forecasts underscores the lingering uncertainty over how quickly the new-vehicle market will shift toward EVs.President Joe Biden set a target of having half of all U.S. new-vehicle sales by 2030 be zero-emission. In November, Biden signed into law an infrastructure bill that included $7.5 billion for EV charging stations and $65 billion to upgrade the nation's electric grid.But plans to extend tax credits to foster EV adoption are now uncertain since the administration ran into a political wall in opposition to its ambitious Build Back Better legislation.John Bozzella, CEO of the Alliance for Automotive Innovation, believes the speed with which Americans adopt EVs will come down to how well the country can build up its charging infrastructure. The alliance, which represents most automakers in the U.S. and many suppliers, in December released a list of recommendations for public charging stations in the U.S. to help bolster EV adoption, including the use of DC fast chargers and stations that can accommodate different vehicle designs."We're moving strongly in that direction," Bozzella said. "But it'll take a significant degree of engagement and partnership across the private sector."In addition to auto manufacturers and suppliers and dealers, it's going to take utilities and builders of residences and commercial buildings and fleet purchasers to step up. And it's going to require thoughtful engagement on the part of government at the local, state and federal level."Their forecasts may differ, but ZF and Magna agree that North America will be slower to adopt EVs than Europe and China. ZF forecasts that EVs will account for 54 percent of Chinese vehicle production by 2030, while EV production in the European Union will account of 59 percent by then.French supplier Valeo forecasts that about half the of the global new-vehicle market will be composed of EVs and other electrified vehicles by 2030. But the rate of adoption will vary greatly by market, said Geoffrey Bouquot, chief technology officer at Valeo, the world's 10th-largest automotive supplier."It depends on the different places and regulations," Bouquot said.Automaker plansElectric vehicle plans dominated automotive activity at CES. General Motors unveiled its long-anticipated 2024 Chevrolet Silverado EV. Stellantis said its Chrysler brand will go all-electric by 2028, and Sony said it is now exploring entering the EV business.Mike Mansuetti, president of Bosch North America, said developing the country's charging infrastructure capabilities will be key to developing trust with consumers on EVs, as well as getting more of them inside of one during a drive."It's sort of like riding an e-bike," he said. "Once you ride one, it's like, 'Wow, I really like this.' "But Mansuetti declined to give a forecast for EV market share by 2030. Bosch is the world's largest automotive supplier, according to the Automotive News Research & Data Center, and the company is investing heavily in EV technologies.The varying supplier views in Las Vegas mirror those of the industry at large, according to a 2021 KPMG survey of 1,118 auto executives around the world.In the survey, executives anticipated that 52 percent of all new vehicles sold in the U.S., China and Japan would be electric by 2030, compared with 48 percent in western Europe. But opinions still varied wildly, with executives giving answers of anywhere between 5 and 90 percent, KPMG global head of automotive Gary Silberg previously told Automotive News.Jamie Butters contributed to this report.source : How big will the EV market be?

LS Mtron captivates the injection molding machine industry with customized multi-shot injection molding!Currently, the injection molding market’s entry level is relatively low in emerging countries such as China and India. However, attempts to improve the value of products by adopting complex plastic surgery technologies are increasing, and plastic surgery techniques to improve productivity are continuously being developed.Among them, multi-shot injection molding machine is a structure that requires high initial setup costs, including IMM and mold costs, and demanding technical skills for materials and processes. In the future, the higher the customer's demand for quality and appearance, the stronger the demand for the injection molding and IMM is expected.At a time when demand for multicolor molding machines is increasing due to the recent advancement and automation, LS Mtron Co., Ltd. will briefly discuss multi-shot injection that can produce simple household goods, high-end interior/external materials and parts, and introduce our products.1. The concept of multi-shot injectionMulti-component injection molding, also known as multi-shot, refers to the process of simultaneously injecting two or more colored and raw materials into a mold to form a single jet2. Type and characteristics(1) Type of multicolored, multiple injection molding① Multi-component injection moldingWith two substances ejected into different liquids and present at the same time as a sandwich structure, the raw material is injected into concentric circles using the same mold/gate, or by repositioning using gates at different locations.② Multi-shot injection moldingIt means making multiple layers based on the starting axis of the initial mold. In other words, heated materials are inserted into the mold one after another in a particular order, which creates a layering effect between materials while maintaining relatively high energy interactions at the material boundary. This means that interlayer bonding is more powerful in that it is a combination under heated and melted conditions, compared to overmolding being injected into existing cooled parts. This is preferred when various molds(different shapes) are needed.③ Over-moldingThis has the most powerful layering effect. This process is used to add shapes and structures to existing components using melted resin, and is an injection method that is applied when layers with various geometric profiles are needed around the central 'core' structure. ▲Types of techniques applied to multicolor injection(2) Type of multiple, multicolored injectionMulti-shot injectin molding can be applied variously depending on the free injection expression and factory installation environment by the customer's product characteristics. In addition, cost can be drastically reduced by omitting post-process processes.In addition, the defect rate in the post-processing process decreases. During the post-treatment process of heterogeneous/different materials, it is also characterized by a reduction in the number of metachromatic stain and poor bonding.Also, additional manpower and facilities are not required according to the existing assembly process, and one-stop production can reduce incidental production time to maximize efficiency.3. Current status and prospects of Multi-shot injection moldingCurrently, many companies have entered the multicolor injection molding market, but each has a low share because it is very subdivided. In particular, the degree of competition is not considered to be relatively high because the injection molding process or control of equipment is more difficult than general injection molding. Especially, multi-shot injection molding are difficult for manufacturers to access because they require a special design, have fewer suppliers, more expensive machines, and are somewhat limited in supply and demand. Therefore, the higher the customer's demand for quality and appearance in the future, the higher the demand for the injection molding and machine is expected to increase.Meanwhile, the advantages of multicolor injection molding are attracting more OEMs to multicolor injection molding. It is possible to mold high-precision parts with various color combinations and one injection machine, increasing the value of the product.Recently, as aesthetic and ergonomic designs have become more important, rubber materials, joining technologies with silicon materials, and seal molding methods are drawing attention. This is also expected to be a positive factor for the multicolor injection molding market(e.g., bicycle handlebars/grips, operating buttons and anti-slip, etc.).▲Increasing demand for multicolored(material) molders4. LS Mtron’s multi-shot injection molding solutionCurrently, LS Mtron provides multi-shot injeciton molding using LS Mtron's accumulated power-driven techniques to control injection volume, speed through multiple injection and digital precision control which injects two or more materials simultaneously or sequentially. In particular, it is possible to change and combine to suit the customer's needs, providing a customized solution to the special purpose customer, and transport it by axis or vertical rotation using the rotational function provided by the machine or mold.Next, I would like to introduce the description and features of our multiple and multi-shot injeciton molding.(1) WIZ-EC① Pneumatic stopper: Easy to replace the stopper and adjust the position of the taper stopper.② Best-in-class rotating plate size: the largest gap between the tie bar in Korea and the extension of the length of the shape③ Rotating plate servo motor drive: Reduce mold rotation time and improve positional precision with index units using AC server④ Option: Application of ejector pin segmentation type(reduction of extraction time) / Application of magnetic plates(2) WIZ-ED① Injection exclusively for LENS- Large specifications of screws can be fitted to primary and secondary injection units- Post-molded products by applying longitudinal pressure injection servo(maintenance time of more than 300 seconds)- Transparent Dedicated Screw Design Applied- Injection Precision Slow Control- Reduce cycle time(2-layered molding)- High-rigid center press plate applied② Molding characteristics- Secondary injection system can be installed without restricting injection volume- Easy to switch into general injection(single product)- Utilization of floor space is relatively efficient(3) WIZ-EV① Vertical structure of a two-liquid injection device: The injection device is mounted perpendicular to the top of the fixed plate and occupies the same space as the standard machine(high-cycle shape high speed application / high-digestion screw applied exclusively for packaging)② Multi-layer technology applied: Technology that improves the formation of blocking layers(EVOHs) on the surface of the product through multi-stage injection▲Multi-Layer technology (4) WIZ-EPR① Molding characteristics- The narrower the gap between the two nozzles, the more space between the four tie bars can be fully utilized to minimize the mold size- Individual control of two injection units results in different injection sequences and increased molding precision- European double injection molds or standard molds can be applied② Core Turn- By applying core turn(index core), 4 portable plates of servo motor injection molding machine are installed to implement individual and simultaneous operation- Simplify mold structure and increase productivity- Fast and accurate core rotation with servo precision control(5) WIZ-EL① Mechanical structure- Additional injection device is located on the semi-manipulated side(determined according to mold structure)- A structure in which two gates are perpendicular to each other in two types of molds- 1st injection device: press + 2nd injection device power type② Scalability- Applicable to existing injection machines or third-party injection machines- Up to 5 additional injection devices can be attached■ Contact: LS Mtron's Injection Molding Machine Division www.lsinjection.com

Freudenberg Sealing Technologies expands testing capabilities for materials used with lithium-ion batteriesPlymouth, Mich. — Demand for lithium-ion batteries is poised for exponential growth as sustainable technologies continue to gain traction in a number of markets including automotive, transportation, electronics, agriculture, mining and construction.Freudenberg Sealing Technologies' latest investment is helping it prepare for that boom.FST expanded the material testing capabilities at its Central Laboratory in Plymouth, adding specially designed spaces, upgraded safety equipment and access to important chemicals and solutions. The expansion allows the company to test the performance and compatibility of materials — rubber, elastomers and thermoplastics — used to safely seal and maintain lithium-ion batteries.F. Joseph Walker, director of research and development for FST in the Americas, said the expansion not only gives customers more robust testing options, it provides new insights."What we can now offer customers is design security, based on scientific data," Walker said in a statement. "… Previous efforts have been conducted to determine the impact of materials on the electrolyte. This work focuses upon the impact the electrolyte has on the materials."The heart of FST's recent investment is a specially designed Isolation and Containment Chamber (IsoC). The IsoC — a two-chambered glass and steel enclosure —adds a layer of safety to the tests conducted with the lithium electrolytic solutions found in lithium-ion battery cells. FST, in describing the "very aggressive" solutions, noted that they "are volatile, toxic and flammable when exposed to oxygen and ambient air moisture."Technicians and chemists involved in the testing also are equipped with head-to-toe protective gear and special respirators; non-reactive, nickel-based immersion vessels; and a safety monitoring and alarm system that can detect spills, leakage, gas formation or other hazards.New technology also allows laboratory chemists to monitor the immersion samples remotely at any time from anywhere using a laptop computer, phone or tablet.Two electrolytic solutions are used in the testing — one commonly found in the lithium-ion batteries and one developed as a control. Families of materials developed by FST will be tested first and commercially available materials used in the batteries will be examined next.Tests, such as those FST plans to conduct, not only require sophisticated safety equipment, they're expensive as well. For instance, the electrolytic solutions used in the testing cost several thousand dollars a gallon, FST said. Nonetheless, the company sees it as money well-spent."We have taken this proactive step on behalf of our customers and in response to a growing use of lithium-ion batteries in diverse applications," Walker said.While the company did not disclose the total cost for expansion, it noted in a March 16 news release that the testing facility and capabilities required a "six-figure investment." The move puts FST in a testing arena where few reside."The risks associated with testing lithium-ion battery materials exposed to electrolytic solutions are real, and the cost of controlling them is one of the reasons only a handful of universities are the only other organizations to conduct such testing," FST said.source : https://www.plasticsnews.com/news/freudenberg-sealing-technologies-expands-testing-capabilities-materials-used-lithium-ionEdit : HANDLER

Automakers seek more ethical, resilient supply chainsElectric vehicle batteries require cobalt.Most cobalt comes from mines in the Democratic Republic of Congo.Congo is a nation plagued by instability and a lack of rule of law that allows some mining companies to exploit their workers.Welcome to the challenge of auto industry supply chain ethics.Supplier disruptions caused by the pandemic are being amplified by concerns about how to ethically source critical automotive materials.The drive has given a new urgency to supply chain transparency. But the work is both labor-intensive and unreliable. Automakers and many Tier 1 parts makers have been trying to peel back the layers of their parts and material sourcing for nearly a decade, especially since a combined earthquake and tsunami in Japan made getting some key materials impossible."We have gone through every step of the supply chain to the cobalt mine to make sure it's ethically correct," Volvo procurement boss Martina Buchhauser said in an online presentation during last month's Financial Times Digital Future of the Car summit. "But what we were missing was a technological way of tracing and putting a ledger on it. And making sure it can't be fiddled with after the fact."In light of the COVID-19 pandemic, Volvo aims to widen this transparency to other parts of its supply chain. "If something happens again," Buchhauser said, "it would be good to have more visibility in the supply chain."Volvo also wants more insight into the ethical sourcing of all of its other parts, and to be able to track its CO2 footprint across the entire supply chain."At our heart is safety and sustainability, and responsible sourcing and CO2 footprint are a big part of that," Buchhauser said. "At first it was a bit funny, because everyone was like, 'Oh, you really mean this?' Now our suppliers are well educated and want the same things."To monitor the origins of their supply of cobalt, both Volvo and Daimler are working with the U.K.-based startup Circulor, a company that tracks vast amounts of purchasing and logistics data in a process referred to as blockchain.Such supply chain analytics have been around for a while, with companies such as ELM Analytics and Resilinc offering to map chains down through all tiers of suppliers. The data is becoming increasingly valuable as automakers and suppliers try to protect themselves from surprise source shutdowns.But identifying every tier is an impossible task, said Ian Harnett, who spoke at the summit just before retiring at the end of July from his position as Jaguar Land Rover's purchasing chief."I would love to know everything all the way down," he said. "But, realistically, I would need an army of people. I would need supercomputers. And the first time a Tier 4 supplier changed one of its Tier 5 suppliers the data is of no use anymore."Worse, it is unclear whether possessing all that data would truly change anything — other than where it concerned conflict materials, such as cobalt.Harnett gave the example of the shiny pigment known as Xirallic, which is used universally in metallic paints and is produced solely in Japan.Xirallic production crashed with the 2011 Japan earthquake and tsunami, halting the output of many vehicles in the U.S."None of us knew what it was," he said of Xirallic. Yet little has changed, he said. "Even after all this time, there's still only one place in the world that makes it."Dual sourcingSome automakers have spoken about the need to increase dual sourcing — relying on two suppliers to make the same part — to avoid breaking the chain in the event of disasters such as the pandemic."This is definitely something we are looking at," Kia Europe COO Emilio Herrera told Automotive News Europe. "We wouldn't want to be in the same situation again, where we depend on a sole supplier."The value of dual sourcing became clear during this year's pandemic. An exclusive reliance on parts suppliers in China's Hubei province, the site of the first outbreak of COVID- 19, cost some automakers dearly, according to a report by the analysis arm of ING bank.But dual sourcing is not an option for smaller-volume producers such as JLR."Making double sets of tools just in case there's an earthquake or some other crisis is simply unaffordable," Harnett said.The massive cost of supply chain holdups means extra scrutiny of this part of auto manufacturing is going to be inevitable."The issue keeps coming up," said Matteo Fini, executive director for automotive supply chain and technology at IHS Markit. "Since the tsunami and Thai floods, around 2011 and 2012, awareness has increased among automakers, starting with the Japanese, and Toyota in particular. They have begun a very thorough exercise to map as much supply chain tiers as possible and have asked their major Tier 1 suppliers to do the same."Suppliers are generally supportive of the process."If you are using new tools — cloud service or digital monitoring — to manage complexity to get a better understanding, it helps all of us," said Thorsten Muschal, executive vice president of sales and program management for Faurecia, as well as president of the European supplier organization CLEPA. "We all have to reduce costs and risk management, and anticipation can do that."He named other benefits as well, such as tracking parts and calculating CO2 footprint, especially when looking ahead to the possibility of CO2 taxes in Europe in the near future. "I would say it was as essential for suppliers as automakers."But some suppliers remain a bit leery about providing automakers with too much insight into a Tier 1 supplier's own supply chain arrangements."There are concerns around what sort of ammunition this transparency could give to an automaker's purchasing department," Fini pointed out. "They could request their Tier 2 or Tier X suppliers to move up the chain, for example."And establishing a blockchain solution is also no simple matter.Two years ago, BMW co-founded the Mobility Open Blockchain Initiative, and last year it completed a pilot solely involving the purchase of front lights.BMW acknowledges the difficulty of tracking a part's origin and supply route when so many players are involved. The goal of the pilot, it said, was to "ensure seamless traceability of components more or less at the push of a button."Andreas Wendt, BMW's head of purchasing and supplier network, said this year that the company's vision is to "create an open platform that will allow data within supply chains to be exchanged and shared safely and anonymized across the industry."source : https://www.plasticsnews.com/news/automakers-seek-more-ethical-resilient-supply-chains

GM steadfast on EV strategy, Barra saysGeneral Motors2018 Chevrolet Bolt EV.Detroit — Even if it's decades before electric vehicles become the dominant form of transportation industrywide, General Motors will continue to take the lead, CEO Mary Barra told reporters Monday.The company remains fully committed to its EV strategy despite interruptions to product programs and factory schedules, and the economic slowdown caused by the coronavirus pandemic, Barra said during a webcast media briefing organized by the Automotive Press Association.Barra told Bloomberg News last week that it could be decades before EVs become the primary mode of transportation, but she added Monday that GM will drive the growth of EV production and sales.Barra is confident that EV sales will gain traction eventually, and especially at GM, "but if you look at the whole portfolio [industrywide] changing over, that tail could be a bit longer," she said.The Chevrolet Bolt is GM's only battery electric option today. But after the automaker previewed the forthcoming electric GMC Hummer during the Super Bowl this year, Barra said customers were excited about its EV plans."We need to make sure that the product is great and that people know about it," Barra said. "We will be making sure we have the right presence and get the right level of information out to customers so they know the vehicles and know what they can do."GM has pledged $20 billion for electric and autonomous vehicle programs through 2025. The automaker plans to have 20 EVs globally by 2023 and is converting a Detroit-Hamtramck Assembly plant in Michigan into an EV manufacturing hub with a $3 billion investment. EV production at the assembly plant has remained on track, despite closures related to the pandemic while some updates to internal combustion vehicles were delayed.The automaker undertook other cost-cutting moves to weather the coronavirus, but Barra said Monday that there isn't a need for further coronavirus-related cost reductions.Battery productionGM also broke ground this year on a battery lab in Ohio to build proprietary Ultium batteries with LG Chem. GM says its battery costs will soon fall below $100 per kilowatt-hour — the threshold widely seen as making EVs competitive with internal-combustion vehicles — and has partnered with Honda to co-develop two Honda EVs. Vans powered by the Ultium batteries could also give GM opportunities on the commercial side. Electrification of commercial vehicles is a" huge opportunity for us," Barra said."We have a steady drumbeat of EVs coming out across segments to appeal to a variety of customers," Barra said. But GM isn't giving up on internal combustion vehicles. The automaker will continue to launch internal combustion vehicles in conjunction with EVs, she said.Barra said GM has a plan to eventually transition some powertrain plants to build EV components, but not all. There will long be a market for internal combustion vehicles, she said.source :  https://www.plasticsnews.com/news/gm-steadfast-ev-strategy-barra-says

'Virtually limitless' opportunities for plastics in changing auto industry, researchers sayDetroit — As the future of automotive mobility and autonomy becomes clearer, advanced plastics are poised to play a significant role, industry professionals and researchers at both the American Chemistry Council and the Center for Automotive Research say.ACC's 2020 automotive road map shows many opportunities for advanced plastics and polymer composites in future car design.An eventual shift to personal mobility isn't possible without plastics, said Gina Oliver, senior director of ACC's automotive team, which developed the road map.The council's plastics division also helped to develop the roadmap, released on March 3, working with researchers and the auto industry to provide insight on technological, cultural and economic trends that it says drive personal mobility and automotive innovation.Two previous road maps focused on regulations and how ACC could help automakers use plastic and composites to improve fuel economy or lightweight a vehicle. But regulation is just "a piece of the larger puzzle," Oliver said."That's still certainly relevant today, but now there's so many new, different drivers happening with the revolution in personal and automotive mobility," she said.Bernard Swiecki, director of Automotive Communities Partnership at CAR, said during Plastics News' March 23 Plastics in Automotive live session that its own technology road map, which came out in November, also shows a space for plastic development, as mild- and high-strength steels decline."I don't think anything here has the same explosion, in terms of growth, that you see in plastics and composites," he said. And that forecast "seems to be basically a world consensus."The challenge for carmakers and suppliers, Swiecki said, will be "getting these materials to play nice together."Materials and autonomyConsidering a pending future of autonomy, Oliver said, plastic components will need to be developed "throughout the entire vehicle.""In order for autonomous vehicles to become a reality, the vehicle is going to have thousands of sensors, radar, lidar and reconfigurable interiors with people out of normal-occupant positions," she said. "All of those sensors are going to need plastics to work."Developers will need to figure out new, movable seating scenarios in vehicle interiors, Oliver said, and how to protect occupants in those configurations."Folks are going to have this new pocket of time and we need to figure out how to protect them doing whatever it is they want to do inside their vehicle, whether it's work at a desk or kids playing video games in the back around a TV," she said. "You're going to have to put air bags in places that aren't normally there in a vehicle, have seat belts in certain configurations and move the seat belts around in the vehicle. … Plastics are the only way to make that happen."Electrification opportunitiesACC's road map also shows many opportunities for plastics and composites to help maintain vehicle performance in electrification."People still want power when they step on the gas pedal," Oliver said. "You have to use a light, strong material, and that's what plastics and composites do."However, Swiecki said, CAR doesn't predict electric vehicles taking ahold of the market, even in the next 10 years."It's a little bit underwhelming compared to some of the really optimistic estimates a decade ago or in 2008 when fuel shot up to four dollars a gallon," Swiecki said. "We still think that close to 90 percent of the vehicles that we sell in 2030 will still be either internal combustion engine working alone or internal combustion engine in a hybrid system."Ride-sharingOliver said automotive OEMs and engineers are already starting to implement more plastic components, instead of turning to traditional materials they were more comfortable with in the past.In a potential future with more ride-sharing and large fleets of vehicles, Oliver said, affordable and easy-to-clean component material will be important for both manufacturers and consumers."Plastics and composites are that tough material on the interior that can be antimicrobial," she said. "We also have the possibility of self-cleaning surfaces. It makes a more pleasant and hygienic experience for all occupants and consumers. People don't want to get into a car that a lot of people have touched that day unless they can feel really confident that it's clean."In this revolutionary time for personal mobility, Oliver said, the traditionally slow-moving automotive industry needs to find solutions and implement them quickly in order to keep up.Doug Gergel, automotive application director at 3D printing startup Carbon, said that additive manufacturing can "make immediate design results a reality.""Suppliers today largely rely on low-volume, single-cavity injection mold tools," Gergel said. "These tools can take 12, 14, 16 weeks to have ready to go, and then there's an iterate cycle to inspect and report the tool."As we're seeing these trends come forward, what I see is greater segmentation amongst automakers, more diverse programs, programs that have go-fast timing and that are relatively low volume," Gergel said "I think additive manufacturing offers value in a lot of those cases."Sustainability and circularityReeshemah Howard, director of strategic programs and partnerships at General Motors, said the automaker's sustainability goals like total end-of-life battery recycling and greater than 85 percent vehicle recycling by mass, among others, call for supplier collaborator for new material innovations in its vehicles."GM currently operates with the circular economy in mind," Howard said. "For plastics, we're evaluating if we can use some additional post-consumer or post-industrial content as well as bio-based materials inside some of our plastics."In 2020, ACC added two new letters to its usual "ACES" road map acronym, to "put a spotlight on" sustainability and circularity, Oliver said."Contrary to popular belief, plastic and composites are recyclable," Oliver said. "There's a lot of opportunity for in-production recycling of waste. We're seeing more and more OEMs utilize that and it drives production cost down for them."Obviously automotive is a more durable good, but at the end of vehicle life, we need to work together to make sure materials can be separated … in order to recycle them, put them back into use for new vehicle production, or maybe turn them into a good elsewhere in the value stream, like water bottles, carpets or whatever that may be," she said.A conversation on how to achieve circularity in the automotive industry, "a huge undertaking," Oliver said, needs to be had across the entire supply chain."This is an infrastructure challenge for everyone in the industry," Oliver said. "Let's have a call to action and identify the existing challenges in terms infrastructure for of end of vehicle life. … We need to work together to define what it means and how to get there."Oliver said plastics allow "virtually limitless possibilities and opportunities for solutions.""In plastics and chemistry, if you tell us what you need, we can create it," Oliver said. But ACC can't actualize a revolution alone, she said. "It's something we all have to do together."ConnectivityCircularitySustainabilityElectrificationSource : https://www.plasticsnews.com/news/virtually-limitless-opportunities-plastics-changing-auto-industry-researchers-say
