Investment Casting Process

Investment casting is less costly than other methods of metal casting work such as die-casting and machined components.

" Near Net-Shape " is a benefit provided by the investment metal casting process that reduces the amount of metal casting material waste and labor costs.

All popular metal alloys can be poured in the investment process giving your project the most versatile design possiblities and highest tolerance controls.

Your finished product has the best quality and finished appearance than methods such as welded assemblies or sand castings.


1. WAX INJECTION
Wax design of the desired castings are produced by injection molding. These designs are called patterns.

2. ASSEMBLY
The patterns are attached to a central wax stick, called a sprue, to form a casting cluster or assembly.

3. SHELL BUILDING
The shell is built by immersing the assembly in a liquid ceramic slurry and then into a bed of extremely fine sand. Up to eight layers may be applied in this manner.

4. DEWAX
Once the ceramic is dry, the wax is melted out, creating a negative impression of the assembly within the shell.

5. CONVENTIONAL CASTING
In the conventional process, the shell is filled with molten metal by gravity pouring. As the metal cools, the parts and gates, sprue and pouring cup become one solid casting.

6. KNOCKOUT
When the metal has cooled and solidified, the ceramic shell is broken off by vibration or knock-out machine.

7. CUT OFF
The parts are cut away from the central sprue using a high speed friction saw.

8. FINISHED CASTINGS
After minor finishing operations, the metal castings becomes identical to the original wax patterns and are ready for shipment to the customer
