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
Casting Process: Sand Casting. Sand casting is a relatively simple production method but has many advantages, particularly for short-run or complex castings with multiple cores or for larger castings.
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.
Sand casting is an economical method of producing metal parts in quantities from one-offs to high volume. It’s the nature of the process that sand cast parts will require machining.
