what is the permanent mold casting?
The permanent mold casting process is the production of castings by pouring molten metal into permanent metal molds under gravity pressure.
|How to make permanent mold?Metal molds usually are made of high-alloy steel or ductile iron, and the life time is from 50,000 to 100,000 or more . The permanent molds should be machined by CNC center and to use some steel cores and sand cores to form cavities. 2D and 3D drawings are available for machining.|
| What is the advantage of permanent mold casting?|
A: Have finer dendrite arm spacing (DAS) and grain structure , so have better strength properties than die casting and sand castings, but less porous than die-castings.
C: Smooth surface finish is achieved right out of the mold, eliminating secondary polishing operations

|What typical parts are suitable for permanent mold casting?|
|Typical parts include valve body (air braking system valve and hand brake valve for automotive industry), pump body, wheels, gear housings, pipe fittings and couplers, fuel injection housings, automotive engine pistons, skate truck etc..|
