The casting process involves pouring molten material into a mold cavity that has the shape of the final part. The material cools and solidifies into the desired shape. 

Here are some types of casting processes:

Permanent mold casting: Also known as gravity die casting, this process uses a reusable mold to produce a large number of castings. The molten metal is poured into the mold, which fills by gravity. The mold is then opened, the casting is removed, and the mold is reused.
Continuous casting: This process produces continuous lengths of metal with a constant cross-section. The metal is poured into a mold and rapidly chilled to ensure a uniform grain structure.
Shell molding: This process is similar to sand casting, but the mold cavity is formed by a hardened shell of sand. The sand is finer than sand casting sand and is mixed with a resin so that it can be heat treated and hardened. 

Other types of casting processes include: Plaster casting, Rapid casting.
