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
be melted and runoff. Then the molten metal is poured in the hollow
and cooled. The castings will be released after the shell mould
1. TOOL MAKING
A wax injection mold is designed and built to produce castings per
2. WAX PRODUCTION
A wax pattern is produced from the wax injection mold.
3. PATTERN ASSEMBLY
Wax patterns are attached to gating system by hot knife.
4. SHELL MAKING
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
Pre-heated Ceramic cavities are poured with the molten metal.
The ceramic shell is removed by vibration knocking and the cluster
Castings are cut off from the gating system.
10.MACHINING,SURFACE FINISH,AND INSPECTION
After cut off and gate removal, all secondary finishing operations
are performed. Each casting is inspected according to customer
specifications and requirements.
