Manufacturing Process

We follow a precision-controlled casting process to produce safe, leak-proof safety valve components. Every step is optimized to ensure reliability and long-term performance.

  • Optimized Mold Design: Guarantees uniform cavity shapes and accurate dimensions

  • Controlled Metal Flow: Reduces turbulence, porosity, and shrinkage defects

  • Stress-Relieving Heat Treatment: Improves toughness, durability, and structural integrity

  • High-Precision Machining: Ensures smooth sealing surfaces and exact tolerances

  • Comprehensive Inspection: Dimensional, visual, and functional checks for secure, reliable operation
