As explained by engineeringproductdesign.com in their article “How does the Sand casting process work?,” sand casting is one of the fundamental techniques in the world of metal casting. It involves a mold made of two halves, known as the cope and drag, contained inside a flask box. This process consists of seven main steps:
- Pattern-Making: Creating an oversized replica of the object to allow for metal shrinkage.
- Mould-Making: Forming a sand mould around the pattern, which includes features like sprues and gates.
- Clamping: Securely clamping the two mould halves together.
- Pouring: Introducing molten metal into the cavity.
- Solidification: Allowing the metal to cool and solidify.
- Shakeout: Removing the casting from the mould.
- Trimming: Cleaning and removing excess material.
Sand casting is a crucial part of the metalworking industry, enabling the production of a wide range of metal parts.
