The Process Flow

1. Product design
2. Mold making
3. Valve casting and forging
   (1) Foundry casting: The earliest production mode in the field of valves, because the casting type does not have enough pressure, the valve produced by this process is easy to produce sand holes, leading to product leakage          and a series of problems.
   (2) Hot forging forging: The body molded by forging will not have trachoma, more beautiful appearance.
