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.

Strong R&D team
Responsible staffs
Clean workshop
We will bring you pistons with good quality and competitive price.
Applications:
Car or motorbike shock absorbers
Competitive Advantage:
XIAYI can produce bands rings to low down the cost and control the quality at home, at the same time we
can design and produce automatic banding machine and non-standard testing machine, can test drawing
force testing and oil immersion testing.
