The product is high quality from start to finish.
01
Ring Profile Machining
Precise Shape of the Ring:
- The precise shape of the ring is crucial for proper sealing within the engine cylinder.
Use of CNC Machines:
- CNC (Computer Numerical Control) machines are commonly used to achieve the exact dimensions and geometry required.
Machining Inner and Outer Diameters and Axial Width:
- The ring’s inner and outer diameters, and axial width are meticulously machined to strict tolerances.
Machining the Profile of the Ring Face:
- The profile of the ring face is also meticulously machined to ensure it meets strict tolerances.
02
Heat Treatment
Boosting Mechanical Properties with Heat Treatment:
- To make our piston rings even tougher, we put them through a heat treatment process.
Precise Heating:
- This means heating the rings to just the right temperature.
Controlled Cooling:
- Then, we cool them down gradually.
Quenching and Tempering:
- This process, called quenching and tempering, gives the rings extra strength.
Enhanced Resilience and Wear Resistance:
- It makes our rings more resilient and much more resistant to wear.
03
Quality Control
Ongoing Quality Control:
- We keep a close eye on quality throughout the entire manufacturing process.
Stage-by-Stage Inspections:
- Our rings go through inspections at various stages to ensure they meet our strict standards.
Precise Dimensional Checks:
- We perform precise dimensional checks.
Surface Finish Checks:
- Evaluating the surface finish is part of our thorough process.
Coating Integrity Verification:
- We also verify the integrity of the coating.
Rejecting Subpar Rings:
- Any rings that don’t meet our criteria are rejected.
04
Packaging and Distribution
Passing Quality Control:
- Once the piston rings pass our rigorous quality control checks…
Packaging for Distribution:
- …they are carefully packaged and prepared for distribution.
Destinations:
- Our rings are shipped to various engine manufacturers, repair shops, and aftermarket suppliers.
Importance of Proper Packaging:
- Proper packaging is crucial to prevent any damage during transport.
