Investment casting (also known as lost wax casting) is a high-precision metal forming process, which is particularly suitable for the manufacture of parts with complex structures and high surface requirements. In the field of valve manufacturing, investment casting is widely used in the production of high-performance valves due to its unique advantages.
Forged valves are valves formed by metal forging process. They have high strength, high density and excellent mechanical properties, and are suitable for high pressure, high temperature or highly corrosive working conditions. Compared with cast valves, forged valves have a denser structure and fewer defects, so they are widely used in key industrial fields (such as petrochemical, electric power, military industry, etc.).
