Description:

20# shock absorber piston with HRB65-80, density 6.5g/cm3, band PTFE disc on OD used in car shock absorbers

Xia Yi was found in 2005, 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 our work efficiency.

We have a technical team to develop automatic banding machine and new generation machine has improved much advantages compared with

previous ones. We improve our pressing machine and other machines to lower the cost and improve efficiency.

The detail information of the pistons:

1. Size: D20, used in automotive shock absorbers

2. Sinter piston material: Fe-C-Cu, banding material: PTFE

3. When temperature reach 100ºС, expansion ratio ≤+/-1%

4. Using the testing ring D20.6, with the shock absorber oil, max frictional force is 15N

5. Piston can get through freely of the certain size of cylinder with 2N force

6. PTFE tensile strength ≥18MPa, breaking tenacity ≥200%

7. Tight integration between piston and PTFE disc. PTFE won't fall off when working in the cylinder.

After processing performance can satisfy the following:

1) Stress cracking test 150ºС*500 hours

2) Drawing load test: 39.2 MPa*10,000cycles

3) High vilocity operation, durability test: 1,000,000 cycles

4) Regular operating durability test: 3,000,000 cycles

No band peel off or breakage after test.

Advantages:

1. Consistency in size for the same batch pistons

2. Infrared ray detect the diameter

3. Produce the PTFE disc by Xia Yi can control the quality itself

4. Enough testing machine can assure the material properties

We can use the following material to produce PTFE discs:

We can add bronze powder or carbon fiber or graphite or other fillers in PTFE

Lip design: We can design no lip, single lip or double lip according to the customer’s demand.

Xia Yi produces shock absorber pistons with many different types. These pistons can be used in front or rear shock absorbers.

We have a strong technical team to research and develop automatic skirting machines. Only need to put PTFE discs and sinter pistons on table,

the machine will do the job to combine them together and finally get the finished PTFE banded pistons.

Applications:

Car shock absorber, Motorcycle shock absorber, Bicycle shock absorber

Competitive Advantage:

Unique material for shock piston bands

Pistons are produced by automatic banding machine can assure the consistency of the size

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. We have an intelligent marketing team who are exploring new markets, developing potential customers, solving problems and serving customers with orders well. We firmly believe that we are a competitive and friendly cooperator and our goal is for mutual benefit and long-term cooperation.
