TROY, Mich.–Last fall, the Automotive Division of the Society of Plastics Engineers (SPE) announced the winners of its 49th annual Automotive Innovation Awards Competition. The announcement was made during the 49th annual SPE Automotive Innovation Awards Gala, held in November at the Burton Manor in Livonia, Michigan.
The Body Exterior category winner was also this year’s Grand Award winner. The Grand Award winner is selected from the winners of each of nine categories by a panel of industry experts.
Following are descriptions of eight of the nine category winners, as well as winners of the Vehicle Engineering Team Award, the Hall of Fame Award, and the Lifetime Achievement Award.
Category Winner, Additive Manufacturing
- OEM Make & Model: 2020 Ford Motor Co. Ford Explorer SUV
- Tier Supplier / Processor: Methode Electronics, Inc. / Methode Electronics, Inc.
- Material Supplier / Toolmaker: Celanese Corp. / RGM Tooling Consultants, Inc.
- Material / Process: Celstran PP-GF20-02 LFT-PP / Injection Molding; 3D Printed H13 Steel
Additive manufacturing was used to produce a single tooling insert (lifter) that replaced two conventionally machined lifters to mold an injection-molded sunglass stowage bin. That enabled design changes to produce a deeper pocket with a heavier undercut that still could be molded without hotspots, warpage, or demolding issues, and without needing to switch to a more costly resin. The new deeper bin design also better meets customer requirements while reducing cycle time, molding scrap, tooling maintenance, and improving dimensional stability in the final part.

Composite Pickup Box
- OEM Make & Model: 2020 General Motors Co. GMC Sierra LD FST pickup
- Tier Supplier / Processor: Continental Structural Plastics/Continental Structural Plastics
- Material Supplier / Toolmaker: Teijin Ltd./Paragon D&E, Model Die & Mold, Inc., Altron Automation, & Legacy Industries
- Material / Process: Sereebo A235Y carbon fiber-reinforced PA6 sheet / Compression Molding
This is industry’s first pickup box in thermoplastic composite and carbon composite. It saved 62 lb/28 kg and provided best-in-class impact resistance/durability. The unpainted UV-stable material eliminated the need for a bedliner (saving another 40 lb/18 kg). Numerous customer features—including functional compartment dividers and motorcycle tire pockets—were molded-in..
The ability to achieve a deeper draw during molding increased cargo capacity. Significant technical challenges were overcome due to use of novel materials, processes, coatings, and joining methods. The box is fully recyclable and some scrap is reused on the vehicle. For more on the pickup box, see GMC Pickup Box Blazing New Path for Automotive Carbon Fiber Composites.

A critical diecast and machined aluminum bracket was replaced by an injection molded bracket in 50 percent GR-PA 6/6 in this demanding rear differential module. The composite material was 30 percent lighter and saved $1 per car in direct costs versus the benchmark aluminum. Its matrix provided 10 times higher damping, improving NVH performance, and it fit current packaging space for this running change. The part passed all performance and durability requirements, eliminated corrosion issues, and will significantly reduce tooling costs over the life of the program.
Category Winner, Environmental
100 percent PCR Carbon Canister Housing
- OEM Make & Model: 2019 Ford Motor Co. Ford Mustang Sports Car
- Tier Supplier / Processor: Delphi Technologies PLC / MGS Mfg. Group

The PP backing from PCR carpeting is given another use life as it is recycled back into the injection molded carbon canister housing for passenger cars. This is the first 100 percent PCR PP-based carbon canister. By replacing virgin PP, the recycled resin reduces cost by 25 percent with no sacrifice to processing or molded-part performance, but increases sustainability. It is currently being rolled out on more than 20 Ford programs globally.
Category Winner, Materials
Glass Wool-Reinforced Composites for Improved Scratch Resistance
- OEM Make & Model: 2017 Hyundai Motor Co. Hyundai Elantra sedan
- Tier Supplier / Processor: Seoyon E-Wha / Seoyon E-Wha
- Material Supplier / Toolmaker: Daehacom Co., Ltd. / Seoyon E-Wha
- Material / Process: SW920 SA glass wool-reinforced PP / Injection Molding
To improve long-term scratch resistance and dimensional stability in injection-molded PP interior trim panels, glass wool (crushed glass and sand produced from reclaimed/PIR building insulation) was used to replace talc, whiskers, and fiberglass. Because glass wool boosts mechanical properties versus talc, filler content was reduced 5 percent, leading to lighter, less costly parts. Because it also helps maintain surface finish longer, it should lower warranty claims. A unique process was developed to incorporate glass wool into the resin compound. Glass wool is difficult to dispose of, so this application gives it another use life.
Category Winner, Powertrain
Transmission Gear Shroud
- OEM Make & Model: 2017 Ford Motor Co. Ford F-150 pickup
- Tier Supplier / Processor: Stackpole International / MacLean-Fogg Co., Engineered Plastics Components Inc.
- Material Supplier / Toolmaker: DuPont de Nemours, Inc. / Gibson Automation
- Material / Process: Hytrel 8238 TPC-ET / Injection molding
A new transmission gear shroud cover and base protect the drive gear so that it rotates freely without needing to push through transmission fluid—lowering effort, improving pump efficiency, and increasing vehicle MPG and the effective life of the transmission fluid.
Injection molded TPC-ET replaced earlier steel covers with rubber seals that were heavier, more complex, and costly, and suffered from more variation. Very aggressive snap fits permanently join the cover to base once the assembly is completed. The same material, molded very thin, provides a ductile seal. Costs were reduced 22 percent, weight lowered 65 percent, and NVH was improved.
Category Winner, Process / Assembly / Enabling Technologies
- OEM Make & Model: 2020 General Motors Co. Chevrolet Corvette sports car
- Tier Supplier / Processor: Shape Corp. / Shape Corp.
- Material Supplier / Toolmaker: SGL Carbon SE, VectorPly Corp., Scott Bader Co. Ltd. / Thomas GmbH + Co. Technik + Innovation KG
- Material / Process: Crestapol 1250 PUR-acrylate reinforced with CF / Radius-Pultrusion
The auto industry’s first pultruded curved bumper beam uses the unique radius-pultrusion process and equipment to achieve a hollow beam with central web in carbon fiber fabric-reinforced polyurethane/acrylate resin. The curved geometry was desired to better match rear styling and vehicle package space. The beam features an integral tow hook mounting and is assembled to the body-in-white (BIW), requiring excellent mechanicals at elevated temperature.
The beam meets low-speed crash requirements while cutting mass by 4.9 lb/2.2 kg versus a metal-inert gas (MIG) welded aluminum extrusion. 3D printing was used to produce mandrels to maintain the hollow interior.
Category Winner, Vehicle Team Engineering Award
