packing detail:

1.put piston one by one into environmental plastic box

2.put 5 plastic boxes into standard carton


No scuffing, Custom Shock absorber Pistons can stand fatigue test and blow-off test


• Big shock absorber piston

• Conventional design

• With PTFE banded on OD

• We can produce according to the customer's drawing

• Middle part (sinter part), we can use the material as the customer's demand

• Carbon content is 0.1%, copper content is 3% or other choice


1. Wear and corrosion resistance

2. Efficiency steaming treatment

3. Reduces friction and ensure smooth rod reaction

4. Teflon banded piston

5. It is equipped with piston rings to provide a good seal between the cylinder wall and piston

6. Increased seal durability

We own the following testing equipment to assure the quality and properties of the mixed material and

banding effectiveness.

1. Tensile strength testing machine

2. Abrasion & friction coefficient testing machine

3. Shore durometer

4. Rockwell hardness tester

5. Density balance

6. Fatigue testing machine

7. Blow-off & friction testing machine

Main property for our shock absorber spare parts:

1. Density of powder metallurgy piston: not less than 6.3g/cm3

2. Density of powder metallurgy valve seat: no less than 6.5g/cm3

3. Density of powder metallurgy rod guide: no less than 6.6g/cm3

4. Efficiency steaming treatment and surface treatment


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.
