Who is EDM Department?

EDM Department Inc. is a manufacturing firm renowned for precision manufacturing and engineering capabilities. As an AS9100D and ISO:9001:2015 certified company, we work in the Aerospace & Defense, Interconnect and Medical & Pharmaceutical industries to produce custom parts from customer provided designs.

What does EDM Department Do?

As our name suggests, EDM Department specializes in EDM Machining, both Sinker EDM and Wire EDM. Supplemental to our EDM processes, we offer precision grinding, micro milling and 3D metrology services. We specialize in tight tolerance work where tolerances down to 1 micron are not uncommon. While our capabilities are perfect for complex prototype projects, nearly 50% of our business remains production work.

Why EDM Department?

At EDM Department, our vertically integrated manufacturing process allows us to produce high quality products with tolerances as tight as 1 micron, (That’s 50X smaller than the width of the human hair!) From one-off R&D prototypes and low volume, high mix to contract manufacturing of full production quantities, EDM Department Inc. has the manufacturing services and expertise required to offer our customers consistent, high quality, precision components at globally competitive costs and lead times. Contact us today to learn how we can help with your next project.

Full Service Manufacturing Focused on Overall Performance

Over 25 years of research and experience have gone into developing the best plans to meet the needs of our customers. We are committed to quality and ensure Cost and Lead-Time are balanced in accordance with customers' individual needs and requirements.
