제품 설명
Elongation @ break ≥ 180% PTFE Banded Piston Produced By Automatic Machine With Steam treatment
We are a professional company to design and produce PTFE banded shock absorber piston, piston size
can be from 20mm to 50mm with different types. We can produce both straight OD and flared OD. we can
also deisgn and manufacture automatic banding machine and piston testing machine.

Product Name: Sintered shock absorber piston
Material: (MPIF 35) FC-0205 (DIN 30910-4) Sint C10, Fe, Balance, Cu 1.5-3.9%, C 0.3-0.6%
Density: 6.4-6.9 g/cm3 after steam oxidation
Hardness: 55-90 HRB, loading 1 kN, diameter of ball 1/16"
Surface Treatment: Steam oxidation, 2 hours, Fe3O4: 0.004-0.005mm, degree of oxidation 2-4%
Unspecified Tolerance: ISO 2768 - m / H14, h14, +- IT14/2
Apperance: No crumbling, cracks, exfoliation, voids, looseness, metal pitting and other defects
Process Flow:
Powder mixing - Forming - Sintering - Oil impregnation - Sizing - Ultrasonic cleaning - Steam oxidation - Oil
impregnation - Final inspection - Packing (+ DP4 bushing / +PTFE band)
Application:
For automobile, motorcycle and bicycle shock absorber
About testing:
We can do blow off testing for shock absorber pistons.
The purpose of this test is to determine the pressure needed to blow the PTFE band of the piston when
traveling in the pressure tube. The test is performed with a constant lateral force applied to the piston
during the pressure build up over the piston. The test is stopped when the pressure decreases due to
PTFE band failure.

Description:
After several years’ effort, we have achieved great success in the enterprise. We
increased our workshop this year and developed several new automatic machines which highly improve
work efficiency. We have a technical team to develop automatic machine and we improve our pressing
machine and other machines to lower the cost and improve efficiency.
We are specialized in design and producing PTFE banded shock absorber pistons,at the same
time,we design and manufacture automatic skirting machines.
Till now we have produced so many different types of shock absorber pistons with the diameter from
ø20mm~ø50mm.We make PTFE discs and toolings in our own factory,can control the quality effectively
and also can save much time.
RAW MATERIAL OF SINTER PARTS:IRON BASED,IRON & COPPER BASED,COPPER
BASED,STAINLESS STEEL BASED
RAW MATERIAL OF PTFE DISC:
PTFE+BRONZE
PTFE+CARBON
PTFE+GLASS FIBER
PTFE+OTHER fillers according to cutomers’ demand
The detail information of the pistons:
1.Used in front shock absorbers
2.When temperature reach 100℃,expansion ratio ≤+/-1%
3.Using the testing ring,with the shock absorber oil,max frictional force is 15N
4.Piston can get through freely of the certain size of cylinder with 2N force
5.PTFE tensile strength ≥18MPa,elongation @ break ≥200%
6.Tight integration between piston and PTFE disc.PTFE won't fall off when working in the cylinder.
Applications:
Car or motorbike shock absorbers
Competitive Advantage:
1. Consistency in size
2. Infrared ray detect the diameter
3. Strict control plan
4.100% testing for outer diameter
