Precision was founded in 1947 by James and Laurette Lewis in West Allis, a Milwaukee, Wisconsin Suburb. Although we have expanded our facilities through the years, the business continues to operate from the same location the Lewis Family established more than 60 years ago.

As a management-owned business, you are sure to find that Precision’s hands-on approach to every aspect of the business guarantees your project will be conducted with the utmost in pride and professionalism.

Our Team

With changing technology and older workers retiring, many pattern shops have lost the core of talent that they once had. While we have embraced the newest technologies to produce tooling, we realize that the “old school” skills are still very much needed in order to attend to all of the details inherent to a job and to bring that job to a successful completion. Our shop team has an average of over 15 years with the company. All of our tradesmen are journeymen or have equivalent experience.

In addition to the skills found on our shop floor, our Sales Engineers have worked as Process, Tooling and Manufacturing engineers in various foundries prior to coming to Precision. We understand tooling projects from your perspective and can better anticipate your requirements when building tooling for you.
