Casting - Lost wax method

Casting parts come from lost wax method : a wood pattern is first created. This wood pattern is used to manufacture silicone mold which is used to realize the waxe pattern. A plaster mold is next carried out around the wax pattern. Molten steel is then put in the plaster mold and replaces the (evaporated) wax.
