Investment Castings

The Investment Casting process begins with producing a heat disposable pattern. This is accomplished by injecting wax or plastic into a metal die. A pattern must be molded for every casting.

These patterns are assembled into a cluster (or tree) and are then coated with various liquid ceramic refractories to form a ceramic shell. The wax or plastic is then melted out of the ceramic shell.

Any number of different alloys can be cast into the ceramic mold. After cooling, the ceramic shell is removed and the castings are cleaned.

Our casting process maintains typical dimensional accuracy of +/-.005" per inch, with a surface finish of 125 RMS or better.

Milwaukee Precision Casting, Inc. produces investment castings in most air melt alloys including 300 & 400 stainless steels, nickel base, cobalt base alloys, as well as carbon and high alloy steel grades.

Many of our satisfied customers have moved their tooling to Milwaukee Precision Casting, Inc. from other foundries, where they had experienced quality or delivery problems. You too can take advantage of our expertise, without any hidden adaptation costs.

Let Milwaukee Precision Casting, Inc. quote your investment casting needs. We would appreciate the opportunity and will respond in 2 working days or less. We are proactive in concurrent engineering and design assistance, and offer some of the shortest lead-times in our industry.

We have built a reputation on our commitment to quality, service, and on-time delivery, which has made us a leader in the investment casting industry
