We are engaged in developing and manufacturing different kinds of shock absorber piston absorber pistons, they have advantages of low friction, good seal etc. We have test machines such as hardness meter (D), projector, analysis balance, friction wear testing machine, blow-off testing machines, fatigue testing machine and so on. Other items that we can't test in our company, we will send standard block samples to Shanghai Plastics Research Institute, so that we can assure the consistency of the raw material.


We have set up good cooperative relationship with some big shock absorber factories home and abroad. Our mass production piston types are:ø25,ø27,ø30,ø31,ø32,ø35,ø36,ø40,ø45.
