Description
In the sand casting process, molten metal is poured directly from a ladle into a sand mold – no high pressure necessary. The mold is created when a pattern made out of wood or plastic — typically called a matchplate — is placed inside an enclosure. Sand is then filled in around the matchplate and inside the enclosure. Once the sand is added and packed densely, the matchplate is removed and the remaining cavity is filled with molten metal. Following the pour, the metal solidifies, the mold is opened and the sand is shaken off the hot casting, which leads to a product being manufactured.
The advantages of sand casting are as follows:
1. Low cost for the casting mould.
2. Simple manufacturing process and short production phase.
