Overview of Investment Casting (or) Lost Wax Method
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.
