It is a combination of plaster mold casting and investment casting. [2] [3] There are two types of ceramic mold casting: the Shaw process and the Unicast process. [4] These casting processes are commonly used to make tooling, especially drop forging dies, but also injection molding dies, die casting dies, glass molds, stamping dies, and ...
Polymer clay is a modelling material that cures when heated from 129 to 135 °C (265 to 275 °F) for 15 minutes per 6 millimetres ( in) of thickness, and does not significantly shrink or change shape during the process.

Its principal use is in making molds for metal casting. The largest portion of the aggregate is a sand, usually silica or sometimes olivine. [1] There are many recipes for the proportion of clay, but they all strike different balances between moldability, surface finish, and ability of the hot molten metal to degas.
Spin casting, also known as centrifugal rubber mold casting (CRMC), is a method of utilizing inertia to produce castings from a rubber mold. Typically, a disc-shaped mold is spun along its central axis at a set speed. The casting material, usually molten metal or liquid thermoset plastic, is then poured in through an opening at the top-center ...
