What Centerline Machine does

Centerline Machine is a Midwest-based precision machining and fabrication company headquartered in Waupaca, Wisconsin, founded in 1996 and operating as a privately held business with 11-50 employees. The company manufactures precision plastic and metal parts, provides machining and fabrication services, and produces custom busbar solutions, with services anchored in direct-to-OEM enterprise sales.

In 2026, Centerline Machine combined with two other Midwest manufacturers, Dielectric Manufacturing and EMS Industrial, to form Dielectric Manufacturing Group, a unified entity targeting electric vehicle OEMs. The combined group claims the industry's broadest single-source capability across precision plastic parts, precision metal parts, machining, fabrication, and custom busbar solutions, drawing on over 60 years of experience from each constituent company (more than 180 years combined). Mike Esser was appointed President and CEO of the parent group.

The company operates a B2B business model, generating revenue through hardware sales of precision-manufactured components and machining/fabrication services. Pricing is not publicly disclosed. The combined entity leverages a single-source supplier value proposition and provides design assistance from concept through production, with direct field-sales engagement targeting EV OEMs as its primary customer segment. Geographic operations remain concentrated in the Midwest, with no disclosed international footprint, certifications, patents, or third-party awards.
