In the process of making the pump and valve castings, it is possible to manufacture blanks with complicated internal cavities, such as various boxes, machine bed, cylinder block and cylinder head. Pump valve castings have large process flexibility and wide adaptability. The size of liquid molded parts is almost unlimited. The weight can range from a few grams to several hundred tons, and the wall thickness can be from 0.5mm to 1m.
Liquid molded parts of pump valve castings are less expensive. Liquid forming allows direct use of waste parts and chips, resulting in lower equipment costs. At the same time, the liquid molding parts have a small processing margin and save metal. Hot forging promotes crystallization and grain refinement, enabling the material to achieve maximum possible strength and consistency with minimal variation between parts. The flow of particles precisely flows along the contour of the valve body. These continuous flow lines help to reduce the incidence of fatigue or common faults.
Pump valve castings can effectively meet the requirements of their design structure, eliminate internal defects, and produce a consistent metallographic structure to ensure excellent performance.http://www.pump-casting.com/
