Pour Molding

Molding, also can be referred as moulding, is the process of manufacturing by shaping pliable raw material using a rigid frame or model called a pattern. It is used to form parts out of metal, plastic, rubber, glass or ceramic in molds. Pour molding is one type of common molding method, which is widely used to make miniature or small parts and parts with simple geometry. A pattern is made and faceted to a work surface. A dam is built around the work surface to contain molten metal or plastic, which is poured into the pattern by a sprue, or channel from the heated chamber.
