PROCESS

Wax Injection: Wax replicas of the desired castings are produced by injecting tooling with wax. These replicas are called wax patterns.

Assembly: The wax patterns are attached to a central wax runner bar, to form an investment tree.

Shell Building: The shell is built by immersing the tree in a liquid ceramic slurry and then coating in a refractory product. Up to 5 layers may be applied in this manner. This stage is the creation of the “Investment mould”.

De-Wax: Once the ceramic shell is dry, the wax is melted out, using an autoclave creating a negative impression of the assembly within the shell.

Casting: The investment mould trees are fired in an oven and pulled out while hot. The shell is then filled with molten metal by gravity pouring. After the mould has been filled, the molten metal is allowed to cool and solidify into the shape of the final casting. Cooling time depends on the thickness of the part, thickness of the mould, and the material used.

Knock off: When the metal has cooled and solidified, the ceramic shell is broken off.

Cut off: The parts are then cut away from the central runner bar using a high speed cut-off saw or band saw.

Finishing: Finishing operations such as grinding or sandblasting are used to smooth the part at the gates. Heat treatment to the final part.

Inspection: All parts are inspected for quality and shipped to the customer.
