A mold containing two or more different parts is called family mold. That is to say, family custom molds have many different parts. Parts that are typically made by plaster casting are lock components, gears, valves, fittings plastic molding, tooling, and ornaments. Sand plastic molds are constructed directly from CAD data. Hot stamping is defined as a dry printing process, which uses controlled heat, pressure, and precision timing to transfer a color pigment from foil to surfaces of varied rapid prototyping samples and materials.
