Ransom & Randolph | Ceramic Shell Casting Process

The ceramic shell casting process starts with wax injection. A die, or tool, is filled with wax, injected in a liquid or a paste form, so it flows into the detail of the mold. Once cooled, the wax piece, or pattern, is removed from the die. Several wax patterns are attached to a wax pole, or sprue.
