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
