Investment Casting Process:
STEP 1:
A wax pattern is produced by injecting wax into an aluminum die.
STEP 2:
The wax pattern which is an exact copy of the required part is released from the die.
STEP 3:
The wax patterns are attached to a wax bar, called a sprue, to form a cluster or tree.
STEP 4:
The tree is dipped (invested) into a ceramic slurry.
STEP 5:
After drying, the coating process is repeated with progressively coarser refractories until a self supporting shell or mould is formed.
STEP 6:
A self supporting shell or mould is finished when the shell has reach the expected thickness.
STEP 7:
Once the mould is dry, it is heated to burn out the wax.
STEP 8:
The tree is fired at a high temperature to cure the mould, remove all residual traces of wax and preheat the mould for pouring.
STEP 9:
Molten metal is poured into the pre-heated mould.
STEP 10:
After cooling on a sand bed, the mould material is removed by vibration, chemical resolution cleaning, or mechanical blasting.
STEP 11:
Parts are cut out from the sprue, lightly ground and if no secondary machining or surface finish required, prepared for shipment.
