Manufacturing Process
We follow a precision-controlled casting process to ensure dimensional accuracy and high strength:
Advanced Pattern Design: Ensures consistent cavity geometry for precise valve function
Controlled Pouring: Minimizes porosity, shrinkage, and internal defects
Strengthening Heat Treatment: Enhances hardness, toughness, and structural integrity
Precision Machining: Achieves smooth sealing surfaces and tight tolerances for leak-proof operation
Rigorous Inspection: Dimensional, visual, and functional checks for safety-critical performance
