F50 - U3 - 64 customized shock piston bands with low wearing and friction coefficient

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:

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.

D31 PISTON:

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

XIAYI, founded in 2006, was set up in a beautiful city Ningbo, which is closed to Ningbo seaport and airport. XIAYI is a specialized factory that is engaged in producing auto spare parts, designing and manufacturing electromechanical & machinery parts and related automatic equipment. XIAYI has a strong R&D team with full of creative spirit. XIAYI develop new products and new equipment every year and was awarded two patents of utility model and invention patents.

The products include shock absorber piston, rod guider, base valve, oil seal, piston rod, bracket, spring seat, valves, guide pipe, bearing bush, copper bush, guide ring, PTFE ring and gasket, in addition XIAYI design and manufacture automatic machine such as banding machine and groove cutting machine.

As a manufacturer, XIAYI insists on pursuing better quality on and on. We control the quality from raw material to assure the consistency from one batch. We have carried out an integrated production system which is based on quality focus. We refer to the rigorous four aspects ( material importing control→ production line control→ QC department control→ logistic department control ) and quality control system to make sure all the products are intact before delivery.

As a seller, our products are exported to the whole world and sold nationally for more than 8 years. About 30% parts are exported to USA, Germany, France, Canada, Brazil, India, Malaysia etc., have set up good relationship with the customers from home and abroad.
