Sand casting is a metal forming process in which a mold is first formed from a three-dimensional pattern of sand, and molten metal is poured into the mold cavity for solidification. The sand shell is subsequently removed after the metal components cooled and formed. Sand casting is a cost-effective and efficient technology, which is generally

· Melting. The glass-making process begins with the melting of the raw materials. The sand, soda ash, and limestone are heated in a furnace at temperatures reaching up to 1700 degrees Celsius. The heat causes the materials to melt and form a molten liquid, which is then poured into molds or fed onto a conveyer belt.

Match Plate Pattern. A match plate pattern is a single piece casting pattern that is commonly used in sand casting. It consists of two opposing sides, the cope and the drag, each with a specific function in the casting process. The cope side has the positive form of the part to be cast, while the drag side has the negative form of the part.
