Xia Yi mainly produce shock absorber pistons with many different dimension.

We have a strong technic team to develop automatic skirting machines which can assure the consistency of the pistons and also can improve the work efficiency.Compared with other suppliers, we are sure we can offer you the best competitive price.

Piston is based on powder metallurgy, filled modified PTFE material, using a special way to combine them together, which has dual advantage of powder metallurgy and PTFE.

(1)Advantage of powder metallurgy:

   Unique chemical composition and machanical physical properties
 

(2)Advantage of PTFE:

   Chemical and aging resistance, temperature endurance and no-sticky performance

(3)Advantage of piston:

    High carrying capacity, good wear resistance, low friction coefficient, good seal and so on
