Casting – Lost Wax Process The lost wax casting process is widely used as it offers asymmetrical casting with very fine details to be manufactured relatively inexpensively. The process involves producing a metal casting using a refractory mould made from a wax replica pattern. The steps involved in the process or the lost wax casting are:
Casting sand is then shaken through a sieve (called riddled sand) so that only fine particles fall around the pattern. This is called facing sand and it must be fine so that detail on the pattern shows up on the final casting. Different types of sand are available. The safest is called petro-bond.
