40mm Density 6.4 g/cm3 Shock Aborber Piston With Radial Crushing Strength 6KN
XIAYI is producing core parts that are needed for automobile Suspension Parts.
Through innovative technology and secure quality, we have expanded our supply to various compete automobile producers and are growing as a core part supplier in this area.
As for parts in the car's shock absorbers, Pistons, Bodies, Rod Guides are assembled. We manage Micron-level solo motor size to control the quality (damping force).
Piston is the most important part for the performance of Shock absorbers. Optimized molding, size accuracy and anti-abrasion PTFE banding process are important.
Base valve is a product that control the flow between the inner and outer tubes in a Shock absorber twin-tube.

Description:
No scuffing, Custom Shock absorber Pistons can stand fatigue test and blow-off test
SPEC: D40XD12X14
• 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
Advantages of products:
1. Wear and corrosion resistance
2. Efficiency steaming treatment
3. Reduces friction and ensure smooth rod reaction
4. PTFE 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
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.
4. Own a whole set of testing machine.
5. Design and produce automatic banding maching by ourselves, improve production efficiency and assure quality in perfect condition.
