In valve manufacturing, precision-cast steel components play a crucial role. These components are produced through precision casting processes, ensuring the reliability and long service life of the valves.

The precision casting process mainly includes wax pattern casting and lost wax casting. Wax pattern casting is an ancient yet modern technique that uses fusible materials (such as wax) to create molds, which are then coated with refractory materials to form shell molds. After the wax pattern is melted and removed, metal is poured into the shell mold. Lost wax casting uses foam plastic molds instead of wax patterns. During the casting process, the foam mold evaporates and disappears, forming the casting.

These precision-cast steel components not only pursue high accuracy and surface quality during manufacturing but also maintain excellent performance throughout their entire service life. They are key components in valve manufacturing, ensuring stable operation and long-term reliability of the valves.
