· Quality
Manufacturing Process
Our end-to-end process control ensures zero-defect quality and perfect OEM fitment.
Raw Material Inspection
All raw materials are strictly inspected and graded to ensure chemical composition meets specified requirements.
In-Furnace Analysis
Chemical analysis and temperature adjustment are performed during melting to ensure stable composition and metallurgical quality.
Pouring & Forming
Molten metal is poured under controlled conditions to achieve consistent shape and internal structure.
Post-Casting Analysis
After casting, chemical composition is rechecked and semi-finished products are inspected
to verify conformity.Heat Treatment
Heat treatment is applied to optimize hardness, toughness, and overall wear performance.
Final Inspection
Each batch undergoes self-inspection, with sampling tests for mechanical properties and metallographic structure to ensure quality consistency.
