Investment Casting: Step-by-Step

All metal casting processes involve the creation of a mold into which molten metal is poured. The outstanding precision and excellent as-cast surface finishes achieved with investment casting are the result of a very precise series of steps as follows:

1. Create a metal die:

Initial tooling can be complex, and expensive. Creating the die is a complex process as the die-maker must take account of expected shrinkage of the wax pattern and of subsequent ceramic investment material.

2. Create a wax pattern:

Wax patterns need to be carefully prepared and checked.

A sacrificial wax pattern is required for each cast component.

3. Create a mold:

Wax patterns are joined to form a tree prior to coating, by then wax patterns are coated in refractory material.

4. Pour the molten alloy:

ceramic molds are heated before filling and retained heat in mold to ensure effective pour.

5. Cooling and mold removal

Once the casting has cooled sufficiently, the ceramic mold can be removed. This is either done manually or using water jets.

6.Finishing

The final stage of the investment casting process is finishing to remove any trace of the gating system and to improve the surface finish, if required. This is often done by grinding or sandblasting. Further processes, such as heat treatment of the component may follow at this stage.
