The
basic steps of the investment casting process are:
-
Production of heat-disposable wax or plastic patterns
in a precision tool.
-
Assembly of these patterns onto a gating system.
-
Investing, or covering the pattern
assembly with ceramic to produce a monolithic mold.
-
Melting out the wax pattern assembly to leave a
precise mold cavity. Firing the ceramic mold to cure the ceramic mold.
-
Preheating the mold for casting and pouring the metal
into the mold.
-
Knockout, cut-off, finishing, and inspection of the
casting.
