Investment casting benefits

The process of investment casting involves a number of intricate steps resulting in components which feature considerable design flexibility and economy. The method compete to some degree with machining, forging, die casting and other processes, but is the only means which combines many of the benefits into one. It can, for example, produce a part which previously required several steps, several parts, and was not as strong ,nor as cost efficient as the investment casting. The net shapes made possible frequently require only minimal finishing.

The process of investment casting

1.    WAX INJECTION

Wax replicas of the desired castings are produced by injection molding. These replicas 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. (Hitchiner prefers to use its superior countergravity casting technology.)

6,  KNOCKOUT

When the metal has cooled and solidified, the ceramic shell is broken off by vibration or water blasting.

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 and inspection, the metal castings--identical to the original wax patterns--are ready for shipment to the customer.
