Specifications:

The Piston Process
Step 1: 100% Laser Inspection of the as-received OD ensures the correct amount of material is applied, thus yielding the finished dimension desired.

Step 2: Computer-controlled application of the Permanently Bonded Band material.

Step 3: 100% Laser Inspection of the OD ensures the desired finished dimension is obtained after process curing the band material.

Step 4: Apply Permanently Bonded 100% pass-thru gauging of each finished piston to assure the piston meets Form-Fit and Functional requirements prior to packaging. Band material via computer controlled metering.

Step 5: Product ready for assembly.

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.

Advantages
The ability to apply the same technology across all types and sizes of pistons affords economies not available with other conventional band methodologies.

100% inspection and close tolerance permits part-to-part and unit-to-unit control of damping forces.

The quality of the material applied eliminates fragment contamination - oil tests following one million cycle bench testing have yielded near original oil quality. This is not typical on units employing a conventional band system.

Close tolerance control affords the closest fit, calibrated leakage around the piston, eliminating potential leak paths and/or uncontrolled leaks due to normal flexible bands distorting and wearing.

No machining cost eliminates the cost to groove the OD of the piston to retain the band.

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. 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.
