What EMS does

EMS Industrial & Service Company is a Richmond, Illinois-based custom bus bar manufacturer founded in 1961, originally producing electrical cabinets and stampings before pivoting into bus bar fabrication in the early 1990s and specializing in copper and aluminum bus bar systems since 2000. The company fabricates custom copper and aluminum bus bars for high and low voltage applications, supported by an in-house manufacturing stack that includes CNC punching, press brake, machining, patented Flow Dynamic Waterjet cutting (60,000 PSI, up to 6" mild steel), in-house fiber laser cutting (two units, up to 2,000 ipm), multi-metal plating (tin, nickel, silver), and electrostatic fluidized bed epoxy coating delivered through local Milwaukee/Chicago partners. Complete bus bar assembly services include precision stamping, bending, custom packaging, and direct end-user delivery, supported by a strategic inventory enabling emergency/urgent order fulfillment with 3-4 week expedited lead times for locomotive customers. EMS holds ISO 9001:2015, ITAR, and RoHS certifications and is an IEEE member.

The business operates a sales-led, direct B2B model with all orders handled through a quote-based system (1-2 business day response) and phone sales (815.678.2700), without any distribution, reseller, or e-commerce channels. Customers are industrial OEMs across seven vertical segments: power generation (wind, solar, hydro, microgrid, generator OEMs, with generator bus bars in 10MW-400MW power range), electric vehicles, transportation (subway, rail, automotive, aviation), telecommunications (cell tower, data center UPS, satellite), marine, locomotive (EMD, GE, Caterpillar), and data centers. Aluminum bus bars handle currents up to 4,000A. Raw material sourcing is exclusively from US-based copper and aluminum suppliers, supporting the ITAR compliance base.

EMS was acquired in October 2025 by Dielectric Manufacturing (Richfield, Wisconsin), joining the Dielectric platform alongside Centerline Machine (acquired 2015), with the stated intent of expanding product availability into EV, power generation, data center, telecom, and defense markets at up to 75% faster production times. Dielectric stated there are no plans to change EMS's operations or workforce, leaving the company as a family-run operating subsidiary within a multi-site contract fabrication group.
