Broomfield Laboratories

What Broomfield Laboratories does

Broomfield Laboratories, Inc. is a fourth-generation, family-owned American manufacturer of high-precision industrial coil and transformer winding machines, headquartered in Leominster, Massachusetts with additional manufacturing operations in Bolton and Sterling. Founded in 1948 by John Broomfield and pivoting to a standard winding-machinery product line in 1980, the company builds a comprehensive portfolio spanning the 100 through 1000 series coil winders (delivering up to 17,000 ft-lbs of torque), foil winding systems, wire flatteners, dereelers and tensioners, trickle impregnating machines, mandrels and tooling, custom machines, and specialty winders for fly, generator, tokamak/stellarator superconducting, and defense applications. Its internally-developed control architecture includes the S-50 and the Linux-based MP5 controllers, with Fanuc also offered, giving customers programmable pitch, turn recovery, and automated layering.

The company sells exclusively through a direct enterprise channel, with 40+ years of export experience into more than 15 countries and a customer roster that includes ABB, Schneider Electric, Eaton, Prolec, GE Healthcare, Philips Healthcare, Raytheon, General Atomics, Caterpillar, Rockwell Automation, GE Vernova, and Hitachi, among others. Revenue is generated primarily through one-time capital-equipment sales of winding machines, supplemented by replacement parts, on-site and phone service, controller programming assistance, preventive maintenance, and machine rebuild/refurbishment services that extend the multi-decade operational life of the installed base. There is no subscription, usage-based, or licensing revenue component; pricing is quote-based and not publicly disclosed.

Following the 2021 acquisition of Thermoplastics Engineering Corporation (TEC), Broomfield consolidated operations across more than 85,000 square feet of manufacturing and office space and brought thermoplastics capability in-house. The business is currently led by third-generation family members Andy Broomfield (President) and David Broomfield (Vice President), with fourth-generation Andrew Broomfield contributing as Production Engineer and Thomas Broomfield serving as President Emeritus. The company received a $300,000 Massachusetts Manufacturing Accelerator grant in 2026.
