Waukesha’s Investment Castings are produced using the Full Mold process. Full Mold Investment
Casting (FMIC) is a type of evaporative-pattern casting process where special foam 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 or foam
patterns machined from stock material through the use of a machining program 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.
