1. Production process Casting: The metal is melted into liquid and poured into a mold, and then cooled and solidified to form the desired shape. This process is suitable for the production of ball valve parts with complex shapes and uneven wall thickness, and it has low cost and fast production speed. Forging: After heating the metal billet to a plastic state, pressure is applied to deform it and finally form the desired shape. The forging process is complex and requires multiple steps, but it can significantly improve the density and mechanical properties of the metal. 2. Performance characteristics Casting: Due to defects such as pores and looseness that may occur during the casting process, its mechanical properties are relatively low, and its strength and toughness are not as good as forgings. However, castings have good fluidity and forming ability, and are suitable for low pressure, low temperature and simple structure occasions. Forging: During the forging process, the metal grains are refined, the internal structure is more compact, and casting defects are eliminated. Therefore, forgings have higher strength, toughness and corrosion resistance, and are suitable for high temperature, high pressure and strong corrosive environments. 3. Application scenarios
Castings: Suitable for mass production and low performance requirements, such as ball valves in low-pressure pipeline systems.
Forgings: Suitable for high-end fields with high performance, precision and surface quality requirements, such as ball valves in high-pressure pipeline systems or key equipment
