Milwaukee Precision Casting, Inc. specializes in both large and small castings – from intricate, miniature parts that are 1/10 of an ounce or less to large investment castings of up to 50 pounds.

Investment casting is an industrial metal forming process used to create wax models, then the models are replaced with melted metals. Firearm components, oil & gas components, medical parts, and more utilize the investment casting process.

The lost wax process is using a wax model and pouring molten metal into the mold. After, the wax model is melted and drained away.

Most metals that can be melted and poured can be used for investment casting. The most common metals are stainless steel, nickel-based steel, cobalt-based alloys, brass, bronze, and copper.

Sand and investment casting have similar processes, but sand casting cannot always make small, intricate parts. Sand casting also often utilizes heavier weight limits, sometimes greater than a ton.

Generally, investment casting has an extensive labor and cost associated with the wax molds, which cause higher costs than forged parts or sand casting.
