Precision Die Casting Services | Since 1968

J&M Precision Die Casting, Inc. has grown since 1968 to a 40,000 square foot facility in Northeast Ohio. In 2015, Rhenium Alloys, Inc. acquired the die casting company specializing in aluminum die casting.

Its employees – the most skilled in the industry – are the hallmark of the operation. We are proud of their talent, employment longevity and unparalleled commitment to high standards. Some unique distinctions that set J&M Precision Die Casting apart are rapid prototyping, high-level engineering precision, and unmatched dedication to service and maintenance. We specialize in high pressure die casting with aluminum, and also develop very high tolerance part designs and tooling for the injection industry.



Doing More For Less

Our versatility enables us to quote competitively and cast competently, whether for long or short runs, large or small parts, simple or complex designs.

We have a wide array of die casting machines and handle many of our secondary operations in house, using our extensive machining centers. We routinely build custom machines for specific customer requirements, in order to reduce their overall costs. Our goal is to efficiently improve the functionality and manufacturability of your designs. We review a design in detail, sharing insights and ideas that allow for a lower-cost end product while improving performance.

Aluminum Die Casting


Aluminum, a light weight alloy that possesses high dimensional stability for complex shapes and thin walls, can be cast to near net shape. Near net shape die casting means the initial production of the part is close to the final net shape. This can greatly reduce the need for finishing techniques and eliminate more than 50 percent of production costs.
