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.
