Grand Award and Powertrain Award – 2017 Ford F-150 vacuum generation system for brake assist
Tier Supplier / Processor: Dayco Products / MacLean-Fogg, Engineered Plastics Co.
Material Supplier / Toolmaker: DuPont Automotive / Kaid Tool & Die
Material / Process: Delrin 73M30 POM+PTFE, Minion 520MP PA6 / injection molding
Airtight to 200 psi (13.8 bar) and leakproof following infrared welding, the all-plastic vacuum generation system (VGS, photo above) consists of 10 components that work together to provide 20% better performance at higher elevations. The open/close valve actuation is accomplished via two complementary resin systems acting in concert to allow no “stick-slip” and no measurable wear after 2.5 million hot/cold test cycles. Injection molding allows for very close tolerances of critical details necessary for total system performance. The design achieved a 40% weight savings and a 25% cost savings compared to current pump systems. Tunable to various engine requirements, the VGS is already employed on four other Ford programs including the Taurus and Explorer, according to a program engineer.
Additive Manufacturing Award – 2017 Ford Mustang Convertible window alignment fixture
Tier Supplier / Processor: Stratasys / Stratasys
Material Supplier / Toolmaker: Stratasys / Stratasys Direct Manufacturing
Material / Process: PA 12 35% short carbon fiber / fused deposition modeling (FDM)
The 3D-printed fixture (above) for the production floor is 30% lighter and cheaper to produce compared to a traditional welded fixture. It took only 50 hours to build the integrated fixture with handles and mounting brackets. Line of sight and ergonomics were improved significantly with the design, which allows for easier handling and precludes the need for a lift assist. The printed fixture also integrates pneumatic control, eyelets for a stowage rack, trigger switch housing, gage protector deflector and pneumatic tubing retainers and switch mounts. “Complexity doesn’t cost you anything” in 3D printing, said George Russell, Automotive Segment Leader at Stratasys.
Body Exterior Award – 2019 Jeep Cherokee thermoplastic liftgate
Tier Supplier / Processor: Magna International Inc. / Magna Exteriors Belvidere
Material Supplier / Toolmaker: Trinseo & LyondellBasell / Tycos Tool & Die
Material / Process: DLGF 9411 & Hifax TYC TPO / injection molding
By replacing a steel liftgate with a new thermoplastic design (above), the engineering team enabled a 28% mass reduction and a 50% tooling and capital investment savings through part integration and manufacturing efficiency. The accelerated 18-month program, from sourcing to Job 1, also resulted in NVH levels that exceeded target. A claimed industry-first use of conformal infrared welding behind the molded-in-color grain class A surface increased structural and dimensional performance and enabled quicker processing. Bonded in brackets enabled patent-pending tethering attachments without fasteners, improved metal reinforcement efficiency and maintained styling surface wrap in D-pillars without sacrificing daylight opening.
Body Interior Award – 2018 Lincoln Navigator integrated modular pelvic bolster
Tier Supplier / Processor: Faurecia Interior Systems / Faurecia Interior Systems
Material Supplier / Toolmaker: LyondellBassell / Roush Tooling
Material / Process: Profax SG702 PP / injection molding
This application combines two unique side-impact bolster designs to meet the requirements for 5th and 50th percentile occupants while achieving an approximate 10% weight savings. Integrating them into the door-trim map pocket resulted in tooling cost savings estimated at $100K. There was an additional $100K indirect savings in testing time and $8-per-vehicle cost avoidance if add-on bolsters were used. The modular mold-in design’s energy-absorbing characteristic can be tuned to accommodate vehicle-specific loading distribution and stiffness requirements. The Lincoln Aviator and Ford Explorer and Escape all incorporate this design now, according to the nomination presenter.
Chassis/Hardware Award – 2016 Chrysler Pacifica self-tapping composite nut
Tier Supplier / Processor: ITW Deltar Fasteners / ITW Deltar Fasteners
Material Supplier / Toolmaker: Asahi Kasei Plastics / Maple Mold
Material / Process: Leona 90G55 PA66 / injection molding
The high-strength composite nut has “self-healing” properties enabling it to maintain sufficient torque and clamp load even after it’s been stripped, unlike the conventional metal nut that it replaces. A mass reduction of 8 g per joint location, times 121 joints on the Pacifica, results in a total vehicle mass savings of 2.1 lb (0.95 kg). The estimated cost savings per vehicle is $3.25. Install drive time was reduced by 400%, with no MAT point or proprietary thread forms required for drawn arc stud. The composite nut can be translated across all OEMs and in many additional applications.
Environmental Award – 2018 Lincoln Continental sustainable hybrid composites
Tier Supplier / Processor: Summit Polymers / Summit Polymers
Material Supplier / Toolmaker: Celanese & International Paper / Summit Polymers
Material / Process: THRIVE & Celstran PP+HC (CF/LGF) PP/RPP / melt compounding followed by injection molding
Claiming an industry-first application of composites combining tree (cellulose) fiber with long glass fiber (LGF) in a polypropylene (PP) matrix, which replaces 35% short glass-mineral filled PP for the console retainer, the program realized a 24% weight savings and 13% cost savings. A total $2 million cost savings resulted by reducing weight and reducing cycle times by 20 to 40%. A lifecycle assessment improvement was also attained. The material is being tested for other “near future” interior and underhood applications such as instrument-panel substrate, door panels, battery trays and fan shrouds.
