Precision casting main processing introduce:
1. Produce a master pattern: Mould-maker creates an original pattern from wax, clay, wood, plastic, steel, or another material.
2. Mould making: A mould, known as the master die, is made of the master pattern.
3. Produce the wax patterns: In one process the wax is poured into the mold and swished around until an even coating, usually about 3 mm (0.12 in) thick. Another method is filling the entire mould with molten wax, and let it cool, until a desired thickness has set on the surface of the mould.
4. Assemble the wax patterns: The wax pattern is then removed from the mould. Attached to a wax sprue, with the result known as a pattern cluster, or tree; As many as several hundred patterns may be assembled into a tree.
5. Investment: Produced by three repeating steps: Coating, stuccoing, and hardening.
6. Dewax: Take 16 to 48 hours to dry, then turned upside-down and placed in a furnace or autoclave to melt out and/or vaporize the wax.
7. Burnout & preheating: The mold is then subjected to a burnout, which heats the mold between 870 ° C and 1095 ° C to remove any moisture and residual wax, and to sinter the mold
8. Pouring: Investment mold filled with sand, The metal is gravity poured.
9. Removal: The shell is hammered, media blasted, vibrated, waterjeted, or chemically dissolved (sometimes with liquid nitrogen) to release the casting.
