Description:
XIA YI is engaged in developing and manufacturing different kinds of shock absorber pistons. Powder
metallurgy based, with PTFE material banding outside, they have advantages of low friction and good
seal properties. In our company, we can test density, friction coefficient, abrasion, blow-off testing and so
on, other items that we can’t test by ourselves we will send standard sample blocks to Shanghai Plastics
Research Institute. 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,
ø46.
SPEC: D25XD8X11.5
Unique design for the fluid channels
Material of sintered piston: Fe-C-Cu
Density is 6.0 g / cm3
Steam treatment
Net weight is 24.32g
Applications:
In car or motorbike front or rear shock absorbers
Competitive Advantage:
1. Consistency in size.
2. Infrared ray detect the out diameter in automatic banding machines
3. Produce PTFE disc by Xia Yi, can control the quality itself.
