Sand casting is a mold based net shape manufacturing process in which metal parts are molded by pouring molten metal into a cavity. The mold cavity is created by withdrawing a pattern from sand that
Sand Casting Procedure. The process begins with a pattern. Patterns should be: Made of a stable material. Oversized to accommodate shrinkage. Include draft angles. Include generous fillets and rounds (avoid sharp corners) Here, a split pattern is used. The two halves of the split pattern nest together.
Sand casting, also known as sand molded casting, is a metal casting process characterized by using sand as the mold material. It is relatively cheap and sufficiently refractory even for steel foundry use. A suitable bonding agent (usually clay) is mixed or occurs with the sand.
Advantages of Casting • Complex shapes • Parts can have hollow sections or cavities • Very large parts • Intricate shaping of metals that are difficult to machine • Different mold materials can be used –Sand, metal, or ceramics • Different pouring methods
The document provides information about the casting process, including key steps and terminology. It discusses making a sand mould through steps like preparing the drag flask, locating patterns, filling and ramming sand, and assembling the cope and drag halves.
