Investment Casting Process And Our Facilities

Inova / Inovative houses the following fully equipped, self - reliant departments for producing Investment castings.

5. Dewaxing
Once the ceramic shell is dry, the wax is melted out either by heating under pressure in an autoclave, or heating in wax bath, creating a negative impression of the assembly within the shell.
6.Casting
The shell is fired at high temperature to sinter the shell, remove all residual traces of wax and pre-heat for pouring. Induction melting furnace is used to melt the metal at desired melting point. Having melted and de-gassed the molten metal, the pre-heated shell is filled to the required level and left to solidity. The cooling rate is strictly controlled to ensure metal purity and casting integrity.
7. Knockout
When the metal has cooled and solidified, the ceramic shell is broken off by mechnical vibration or water blasting or chemical cleaning. The parts are cut away from the central sprue by conventional engineering methods.
8. Finishing
After minor finishing operations, the metal castings (identical to the original wax patterns) are ready for shipment to the customer.
