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!
