Manufacturing Process
We use a controlled investment casting process to produce high-quality, leak-proof wafer type non-return valve components, ensuring reliability and long-term durability.
Optimized Mold Design: Guarantees uniform cavity shapes and consistent casting quality
Controlled Metal Flow: Reduces shrinkage, turbulence, and internal defects
Durability-Enhancing Heat Treatment: Improves hardness, toughness, and structural integrity
Precision CNC Machining: Achieves smooth sealing surfaces and exact tolerances
Comprehensive Quality Checks: Dimensional, visual, and functional inspections to ensure leak-proof operation under backflow conditions
