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.

Competitive Advantage:

Investment Casting is generally more expensive than it\'s associated metal casting methods of \"die casting\" or \"sand casting\", but can produce complicated shapes that require little rework or machining. Investment casting is used in many advanced technical industries such as Aerospace, Power Generation, Oil & Gas, Military & Defence, Medical, Commercial and Automotive.
