Customized PTFE Banded Piston Produced By Automatic Machine With Steam Treatment

Elongation @ break ≥ 180% PTFE Banded Piston Produced By Automatic Machine With Steam treatment


XIAYI is 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.



STEP ONE



STEP TWO



STEP THREE



1.design and sell PTFE disc


2.design and sell banding machine



1.fit with sinter piston


2.solve the installation problem, with good seals and elongation @ break



1.fit with front and rear shock absorber


2. reduce cost and good quality guarantee



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:


Xia Yi, found in 2006, 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.

XIAYI company is 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
