4 pairs oil holes 32mm PTFE banded Shock Piston with hardness 57-67 HRB applied in cars
XIAYI can mix PTFE and other fillers together, get the sintering PTFE cylinder.
We can also produce PTFE ring discs, can band PTFE in our house.
XIAYI can also design and manufacture PTFE piston banding machine.
We produce this machine by our own purpose, sell out to other powder metallurgy and shock absorber
factory for such machine.
