How to Cast Polystyrene

2017/4/12Casting with polystyrene is used to manufacture metal molds that later house a variety of materials. The process is referred to professionally as a lost-foam process or a full mold process because the polystyrene is vaporized and replaced by the molten metal, leaving a mold in its place.

Casting (metalworking)

In metalworking and jewelry making, casting is a process in which a liquid metal is delivered into a mold (usually by a crucible) that contains a negative impression (i.e., a three-dimensional negative image) of the intended shape. The metal is poured into the mold through a hollow channel called a sprue. The metal and mold are then cooled
