Uring method and advantages of pump valve castings

Oct 15, 2018

The casting of the pump and valve castings generally does not apply pressure, and the strength of the equipment and the mold is not high. The size limit of the product is smaller than that of the pump valve casting, and the internal stress in the product is also low. Therefore, the production investment is small, and large-scale parts with excellent performance can be obtained. On the basis of the conventional casting, methods such as pouring, insert casting, pressure casting, rotary casting and centrifugal casting are derived.

Perfusion of pump valve castings: This method differs from casting in that the cast product is removed from the mold, and the mold is an integral part of the product itself.

Inlaying of pump and valve castings: Various non-plastic parts are placed in the mold cavity and solidified together with the injected liquid material to be encapsulated therein.

Pressure casting of pump valve castings: Applying a certain pressure to the material during casting is beneficial to injecting viscous material into the mold and shortening the filling time, mainly for epoxy resin casting.

Rotary casting of pump valve castings: After the material is injected into the mold, the mold rotates at a lower speed around a single axis or multiple axes, and the materials are distributed by gravity on the inner wall of the cavity, and are shaped by heating and solidification. Used to manufacture hollow products such as spheres and tubes.https://www.pump-casting.com/
