Product Specification

We manufacture high-precision piston rings in multiple materials and configurations to meet diverse industrial requirements.

To manufacture piston rings of any size, there are nearly 9 to 15 steps, depending upon:

(1) End of Joint Types:

• Butt Joint • Angle Joint
• Step Joint
• Angle Step Joint
• Convex Joint • Hook Joint

(2) Piston Ring Types:

• Plain Ring
• Compressor Ring
• Oil Ring
• Oil Ring with Spring
• Chrome Plated Ring

Manufacture Standards

Casting, facing, grinding, and turning are common processes for each ring.

All processes are carried out using highly sophisticated machines, operated by experienced workers with precise tools and fixtures. Precise inspection is carried out by well-trained inspectors with very high-precision imported instruments. Jigs & Fixtures and precision instruments are calibrated periodically.

Surface Treatments

Surface treatments are designed to provide: Corrosion protection during storage.Enhanced appearance Improved running-in characteristics


(1) PHOSPHATING (Manganese Phosphate Coating)

• Thickness: 2-5 µm
• Process: Chemical transformation into phosphate crystals
• Benefit: Softened surface accelerates ring bearing
• Application: General purpose protection

(2) BLACK OXIDING

• Thickness: < 1 µm
• Process: Thin iron oxide layer formation
• Benefit: Corrosion protection during storage
• Application: Cast iron ring sides
• Cost-effectiveness: Budget-friendly option
