Description of Investment Casting Process:

 

1.DIE MAKING

A wax die is designed and built to produce castings per customer specifications.

2. WAX PRODUCTION

A wax pattern is produced from the wax die which works a wax injection machine.

3. PATTERN ASSEMBLY

Wax patterns are attached to runner system by hot knife.

4. CERAMIC SHELL MAKING

The pattern assembly is dipped into a ceramic slurry, coated with a refractory material and get dried. The process is repeated until the desired thickness and strength is achieved.

5. DEWAX

A high-pressure 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 cluster are poured with the molten metal.

8.KNOCK OUT

The ceramic shell is removed by vibration knocking.

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 like linlishing, shot blasting, CNC machining are performed. Each casting is inspected according to customer specifications and requirements.

Applications:

 

Mechanical Components in Valves&pumps,Marine, oil, gas, medical, military, electronics industries. 
 
 
 

Competitive Advantage:

 

For lost wax casting method:

  • Allows greater design freedom high complexity parts
  • Can cast a wide variety of alloys even which melting temperature is higher than die steel
  • Yields lighter, stronger metal parts with superior finishes
  • Reduces greatly on tooling and machining costs
  • Possible for rapid prototype development
