HOW IT WORK
Patternmaking
To create a casting mold, a manufacturer must first design a physical model. the method of fabricating this model is named patternmaking.
Coremaking
Cores are solid materials placed inside the mold cavity to make interior surfaces of a casting. for instance , a metal pipefitting would require a cylindrical core inside the mold cavity to make the hollow construction of the component's interior.
Molding
The manufacturer can create the casting mold. a cloth like sand is employed in expendable mold casting, whereas metal and other durable materials are utilized in non-expendable mold casting techniques.
Melting and pouring
Metal must be properly melted before being placed within the mold. Crucibles are containers made from porcelain or another melt-resistance substance, Then melted metal is poured into the casting mold to chill and harden.
Finishing
Because metal can sometimes fill in cracks during a casting mold or sprues, the pouring channel for the mold. Once proper appearance and surface texture has been achieved, further treatment like painting or electroplating could also be necessary.
