Stainless Steel Castings / Custom made / Lost Wax Casting Process
The Investment Casting Process
Investment casting requires the use of a metal die (usually aluminum), wax, ceramic slurry, furnace, molten metal, and any machines needed for sandblasting, vibratory tumbling (with or without a grinding or polishing media), cutting, and grinding. The investment casting process involves the following steps:
Pattern Formation – Lost wax casting patterns are created by injecting molten wax into an aluminum alloy die.
Assembly – Single molds can be created, or tree-like precision investment casting molds can also be created for larger scale production runs.
Shell Building – The investment castings outer shell casing is built up through dipping into a ceramic bath and then immediately coated with sand several times.
Dewaxing – The inner cavity of precision investment casting is then dewaxed, which leaves a hollow outer ceramic shell layer.
Pouring & Solidification – The ceramic cavity is then heated and cured. This prevents shock and the ceramic shell from cracking once the liquid metal is poured into the casing.
Sawing/Cutting – Once the metal has cooled, the cast part(s) is then removed from the sprue or tree cluster via a radial blade cutting or friction sawing off the individual cast part.
Customization – The part is then fully customized through grinding or additional heat treatments. Secondary machining may also be required depending on the requirements of the part.
Finish – The part can be supplied with a standard 125 RMS sand blasted finish, media polished, plated, painted, or coated.
