Investment Casting Process:
1. TOOL MAKING
A wax injection mold is designed and built to produce
castings per customer specifications.
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.
5. DEWAXING
Using regulated steam pressure, an autoclave melts and remove
the wax from the ceramic shells.
6.SHELL PREHEAT
High temperature ovens cure and preheat the ceramic shells
before pouring.
7. CASTING
Pre-heated Ceramic cavities are poured with the molten
metal.
8.KNOCK OUT
The ceramic shell is removed by vibration knocking and the
cluster is cleaned.
9.CUT OFF
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.
