We produce different size of shock absorber pistons. These pistons can be used in different car or


motorcycle shock absorbers.


Sinter pistons based, band PTFE rings on outside, can assure the good seal and wear resistance.


Processing for sinter pistons    


Mixing powder——Forming——Sintering——Sizing——After treatment——Steam treatment——Oil




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) tester


Rockwell hardness tester


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.


PTFE piston ring banded on sinter piston


PTFE coated bushing reduces wear


Four round holes & six square holes design


Shock Absorber Type: Hydraulic


Wear resistant piston ring reduces friction and possibility of leakage


Certification: ISO/TS16949




Used in car or motorbike shock absorbers


Competitive Advantage:


We can produce bands rings by itself to low down the cost and control the quality at home, at the same


time we design and produce automatic banding machine and non-standard testing machine, can


test drawing force testing and oil immersion testing.
