The Brief Introduction of Metal Casting Process

The metal casting process is a complex process with combined working procedures. It includes the following main processes: first metal casting process is the preparation of production technology. Workers should make production plans and process files, draw the flow chart of machine tools and castings according to the pictures of castings to produce, production batch and delivery deadline. Second metal casting process is production preparation, including preparation for melting materials, modelling core materials, core box, sand box and other process equipment. The third process is modelling and making the core. And the last metal casting process is melting and casting;

Metal casting process is a metal forming method that makes the metal heated to be flowing, and then pours it into the mold cavity with a certain shape. Under the force of gravity or external power, such as pressure, electromagnetic force, centrifugal force, the casting cavity will be filled with liquid metal. After cooling and solidifying into machine tools, the metal castings will be finished.

Metal casting process will be the machining parts by cutting process. But there are many castings ofmachine tool without cutting process which can meet the precise requirements of the design and surface roughness. They can be directly used as machine parts.
