Investment Casting Process

Tooling and Patterm Making

A tool is built to customer provided specifications (A). Cold wax is then injected into the tool to create a wax pattern/prototype (B) that will hold precise dimensiona requirements in the final casting.

Pattern Assembly

The wax patterns are assembled onto the sprue.

Dipping and Coating

Successive layers of ceramic (A) and stucco (B) are applied to the sprue assembly to form a hard shell.

De-Waxing and Firing

The molds are flash-fired to remove the wax and sprue materials and then heated to 1,800° and placed ona sand bed, ready for pouring.

Casting

Molten metal, up to 3,000°, is poured into the hollow mold and then cooled.

Knockout

The ceramic shell is broken off, and the individual castings are cut away.

Finishing

Excess metal is removed, surfaces are finished, and castings are heat treated.

Testing and Inspection

Castings undergo thorough testing and inspection to ensure that they meet dimensional tolerances and specifications.

Packing and Shipping

Castings are securely packaged for shipping to the customer.

As you know the Investment casting is one of the oldest metals forming processes in the world.
