Shell Moulding Casting

Shell Moulding is a high-grade production of sand-casting process, producing the highest quality of casting available with modern technology. In contrast to sand casting, the shell moulding’s sand is heated, so that when the resin sand touches the pattern, it creates a thin ‘shell’ around it. This shell becomes the negative pattern forming two pieces. These two pieces are then mated to create a mould, which molten metal is poured into. The cast part is then retrieved by breaking the shell away from it. The manufacturing process is completely automated, which lowers labour costs and facilitates mass production.
