PTFE banding piston

Use in front shock absorbers


We produce shock absorber pistons with variety types. These shock absorber pistons can be used in different shock absorbers such as Nissan, Hyundai, Buick, Benz and so on.


Our productive capacity:

We have a strong team to research and develop automatic banding machines. The annual capacity can reach more than 20,000,000 nos.


There are plenty of testing machines in our company.


Tensile testing machine which can test tensile strength & elongation @ break according to GB/T 1040.2/1B-2012


abrasion testing machine which can test friction coefficient & abrasion loss according to GB/T3960-1983(1989)


Density balance can test material density to assure the material quality and homogeneous distribution


Shore hardness (D) meter

Projecting machine


We also develop the testing machines by our team workers. For example: blow-off testing machine, fatigue testing machine and friction testing machine.


Here are physical properties of the products:                  

Tensile strength 16N/mm2        

Hardness (D):52-62             

Working temperature:-80°C to 260°C           

Friction coefficient (dry) ≤0.20

Elongation @ break: ≥150%





Car or motorbike shock absorbers


Competitive Advantage:


We are a professional company which produces different size and design shock absorber pistons.

We have a complete set of testing equipment which can control the quality for the material.
