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& acute;s associated metal casting methods of & quot;die casting& quot; or & quot;sand casting& quot;, 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.
