Investment Casting

Waukesha Foundry Investment Casting – Proven and Capable

When your casting project demands the tightest tolerances and best surface finish, Waukesha’s proven Full Mold Investment Casting process is the solution. Our castings are recognized throughout the industry as being the preferred choice for mid to large size castings featuring complex geometries and/or intricate designs with varying section sizes.

Process Description

Waukesha’s Consumable Pattern Ceramic Molding provides Investment like Castings. The process is a type of evaporative-pattern casting where special foam, polymethyl methacrylate acrylic (PMMA) or stereolithography (SLA) is used for the pattern material instead of wax as in the traditional investment cast process. The process employed at Waukesha utilizes foam patterns produced from dedicated dies in higher production applications, foam patterns machined from stock material through the use of a machining program, or printed PPMA / SLA developed from a customer supplied model.

The foam patterns are then processed through a slurry/stucco application similar to the lost wax process and the ceramic shells are then completed through a kiln drying process to achieve their maximum strength and finish prior to casting.
