This document summarizes various casting processes and their requirements. It describes sand casting, die casting, shell mould casting, investment casting, and centrifugal casting. For each process, it provides an overview and the main steps. Some key points include that sand casting uses sand as the mold material and accounts for over 70% of metal castings. Die casting forces molten metal under high pressure into tool steel dies. Shell mould casting uses a resin-covered sand to form expendable molds. Investment casting is also called lost-wax casting, one of the oldest metal forming techniques. Videos are also included to demonstrate each casting process. Mold cavity, melting, pouring, solidification, mold removal, and cleaning are identified
