What is Investment Casting and the Process:

Definition of: investment casting -
A casting process in which wax pattern is surrounded by an investment compound(ceramic shell) and then baked so that the investment is hardened to form a mold and the wax pattern material may
be melted and runoff. Then the molten metal is poured in the hollow and cooled. The castings will be released after the shell mould knockoff.

A wax injection mold is designed and built to produce castings per customer specifications.

A wax pattern is produced from the wax injection mold.

Wax patterns are attached to gating system by hot knife.

The pattern assembly is dipped into a ceramic slurry, coated with a refractory material and dried. The process is repeated until the desired thickness and strength is achieved.

Using regulated steam pressure, an autoclave melts and remove the wax from the ceramic shells.

High temperature ovens cure and preheat the ceramic shells before pouring.

Pre-heated Ceramic cavities are poured with the molten metal.

The ceramic shell is removed by vibration knocking and the cluster is cleaned.

Castings are cut off from the gating system.

After cut off and gate removal, all secondary finishing operations are performed. Each casting is inspected according to customer specifications and requirements.
