Reducing costs with design assistance and

       our extensive manufacturing capabilities.

Manufacturing Capabilities

J&M Precision Die Casting specializes in Aluminum Die Castings and Zinc Die Castings. We supply outstanding technical support to our customers on the entire die cast process.

J&M Precision Die Casting, Inc. operates in a 40,000 square foot facility in Elyria, Ohio (near Cleveland) (Made in USA). We have a wide array of die casting machines and secondary operations equipment to meet your needs. Our melting furnaces hold up to 10 lbs. to 1200 lbs. of metal. Because we handle many of our secondary operations in-house using our extensive machining centers, we routinely reduce costs for our customers. Our highly skilled engineers also frequently build custom machines for specific customer requirements, further reducing manufacturing costs.

We are a proud member of The North American Die Casting Association (NADCA). We are a subsidiary of Rhenium Alloys, Inc., a leading manufacturer of refractory metals and high temperature products also based in Northeast Ohio.

Cost Reduction and Design Assistance

Our mission is to help our clients improve the functionality and manufacturability of their designs. We review designs in detail and then provide insight and ideas to lower costs while improving performance of the end product.

J&M Precision Die Casting can reduce or eliminate secondary operations such as drilling, reaming, threading and machining on some castings, thus reducing scrap and overall cost for the finished part.

In our thorough design review, we will propose ways to tap and drill holes and openings both vertically and horizontally to lower overall cost. We also explore material usage and suggest alternatives that reduce cost. We quickly and economically machine metal-forming dies used in industrial part production.

Let us help to improve your designs and reduce the cost of your die casting projects. Contact our team today.
