Top 8 Motor Laminate Manufacturers in the USA 2026

Laser Technologies operates a 168,000-square-foot facility in Naperville, Illinois, running production around the clock. What sets the company apart is process flexibility: it offers both laser cutting and traditional stamping under one roof, along with lamination bonding, core-plate coating, welding, and CNC machining as in-house secondary services. That combination makes it a practical option when a program needs to move from prototype to production without switching suppliers.

The company is ISO 9001:2015 certified, ITAR-registered, and NADCAP certified, and it serves the electric motor, aerospace, military, marine, medical, and nuclear industries — sectors where documentation and traceability matter as much as the parts themselves.

Founded in 1964 and based in Maple Shade, New Jersey, Thomson Lamination (TLC) built its reputation on tight-tolerance laminations for mission-critical rotating components — originally guidance and control systems, later expanding into medical, semiconductor, and telecommunications applications. The company runs its own tool room and an in-house annealing department with atmospheric furnaces, which lets it control magnetic performance from raw coil to finished lamination without outsourcing any step.

TLC holds AS9100D, ITAR, NADCAP, and ISO 9001:2015 certifications and is DFARS, RoHS, and REACH compliant — a certification stack aimed squarely at aerospace and defense buyers who need full supply-chain documentation.

Based in St. Paul, Minnesota, LCS Company has been stamping electrical laminations for more than six decades, ranging from half-inch instrument components up to 24-inch-diameter generator cores. Its press capacity spans 3 to 330 tons, giving it room to handle both delicate prototype runs and large production volumes on the same floor.

LCS works with cobalt and nickel alloys, silicon steels (M15–M45), and insulator materials like Nomex and Delrin, and it serves aerospace, medical imaging (MRI and X-ray equipment), and missile-guidance applications alongside standard industrial motors. Beyond laminations, LCS also produces related precision-stamped hardware — shims, washers, brackets — which can simplify sourcing for programs that need more than just the core stack.

Precision Micro takes a different approach than the other companies on this list. Headquartered in Birmingham, UK, and serving customers in more than 30 countries, it specializes in photochemical (chemical) etching rather than mechanical stamping or laser cutting. Because etching is a non-contact, non-thermal process, it avoids the cutting-edge stress and heat that can degrade a lamination's magnetic properties — and because it uses digital tooling instead of hard dies, design changes can go into production in days rather than weeks.

That makes Precision Micro a strong fit for prototyping, design iteration, and low-to-mid-volume runs of thin or intricate laminations, though mechanical stamping generally remains more cost-effective at high volumes. The company is IATF 16949 certified for automotive work and has over 60 years of experience in precision etching.

UPG Electrical, based in Monroe, Wisconsin, has been producing electrical steel laminations since 1966. The company (formerly Orchid Monroe, acquired by UPG Enterprises in 2022) runs high-speed lamination stamping alongside precision steel slitting, aluminum rotor die casting, robotic welding, and annealing — a vertically integrated setup that has produced more than 100 million die-cast rotors to date.

UPG's part range runs from tiny laminations for medical devices up to large cores for locomotives and wind turbines, and it has built specific expertise in EV traction-drive rotors, including X-ray inspection of die-cast cores for porosity — a detail that matters for high-reliability EV programs.

Oberg Industries, headquartered in Freeport, Pennsylvania with five U.S. facilities, has one of the longest track records in this space: it introduced tungsten carbide stamping dies in 1948 and produced its first rotor-stator lamination dies in 1950. That tooling heritage still defines the company today — Oberg designs and builds its own progressive dies in-house, running presses at up to 1,200 strokes per minute with bed sizes as large as 145 inches.

In recent years Oberg has leaned into EV and hybrid vehicle programs specifically, with a dedicated try-out cell for testing next-generation stamping dies against the ultra-thin lamination materials used in modern traction motors.

Founded in Chicago in 1945, Tempel is one of the largest and most globally distributed names on this list. Beyond its Chicago headquarters, the company operates manufacturing facilities in Canada, Mexico, China, and India, giving it a footprint few contract lamination manufacturers can match. Tempel was acquired by Worthington Industries in 2023 and now operates as part of Worthington Steel (NYSE: WS).

Tempel's scale makes it a natural fit for automotive, HVAC, appliance, and energy programs that need consistent, high-volume lamination supply across multiple regions rather than a single-site domestic source — though that scale can mean less flexibility for small prototype or niche runs compared to smaller specialty shops.

ANDRITZ belongs in a different category than the other seven companies on this list: it isn't a contract manufacturer you buy finished laminations from — it's a supplier of the press-line equipment used to make them. Through its Kaiser division, headquartered in Graz, Austria, ANDRITZ builds complete electric motor lamination production lines — feeder, press, stacker, and scrap conveyor — engineered to hold tolerances down to 0.02 mm.

If your organization is evaluating whether to keep lamination production in-house rather than outsource it, ANDRITZ is worth knowing as an equipment partner. If you're looking for a company to produce laminations for you, the other suppliers in this guide are the more relevant comparison set.
