Shock absorbers for automobiles

• Improve driving experience by reducing force required to damp shocks
• Prolong service life and flexibility of the elastomer seal
• Superfinishing hard chrome coating (1,500 Hv) to reduce Rpk is expensive 

FriCSo’s polymer lapping adds an oil-retaining organic nano-layer and produces an extremely flat, smooth superfinished surface. Polymer lapping is effective even on very hard metals. 

• Improved the coefficient of friction of chrome-plated parts (hardness Rc 74)
• 50% reduction in Rpk
• Entire process can be adopted to the current in-line production process, without additional capital expenditure, and without affecting throughput
• Better performance for end-user
