Frequently Asked Questions (FAQs)
What is the process of sand casting, and how does it work?
Sand casting involves creating a mold using sand, into which molten metal is poured to form the desired shape. The process starts with mold-building, where sand is packed around a pattern that replicates the shape of the casting. Once the mold is ready, molten metal is poured into it. After the metal solidifies, the sand mold is removed, and any excess material is trimmed. This method allows for the production of complex shapes and large metal parts.
