Metal casting is a traditional method of working with metal that requires the cooling and melting of molten metal in the mold to create components. It is a highly sought-after method that companies use to produce metal parts, despite its long history.
High-pressure casting is a process wherein molten metal is forced, under pressure, into a sealed mold cavity. Since the advent of metal casting, the methods have evolved and varied. Its core techniques, however, have remained constant. You can also look for the best metal casting software online.

Here is a general step-by-step process for metal casting:
Step 1: Patternmaking
In order to begin the metal casting process, a manufacturer first must develop a representation of the desired pattern. This pattern is essential in designing the mold used for the cast.
It is traditionally made from wood, foam, plastic, or wax and ensures that the mold accurately produces the finished metal part. Today, 3D printing is also a common method to produce patterns, which allows designers to create accurate patterns directly from digital CAD software tools.
Step 2: Moldmaking
The next step is creating a casting mold, which can be either reusable (non-expendable) or non-reusable (expendable).
Non-reusable molds are usually made out of sand, plaster, wax, or by 3D printing, and just as the name suggests, they get destroyed in the casting process. Reusable molds are made out of metal and other durable materials and can be reused for multiple casting cycles.
