We are glad to announce we are one of the finalists of the SPE IAG22 in the category of Powertrain.
We made the list for our hard work on making the Start /Stop Accumulator Piston.
Some information about our entry:
OEM Make & Model: 2020 General Motors Co. Chevrolet Equinox
Tier Supplier/Processor: Borg Warner, Inc./ NMC Dynaplas, Ltd.
Material Supplier/Toolmaker: DSM Engineering Materials / NMC Dynaplas, Ltd.
Material /Process: Stanyl TW241F12 PA4/6/ Injection Molding
By switching from aluminum to 60% GR-PA4/6 on an accumulator piston, 2 polymer wear bushings were eliminated while lowering wear, and cost and mass were reduced 47% and 70%, respectively. The highly efficient part design met all performance requirements for fatigue, thermal cycling (-40°-140°C), chemical resistance, wear, creep, and fluid pressure/spring force resistance.
Well done NMC Dynaplas Team!
Here is the winning part:
