Two Manufacturing Paths. One Standard of Quality.

We tailor our manufacturing process to your volume and timeline.

For R&D and Prototypes: Our Laser Cutting services allow for rapid iteration without tooling costs. We can cut complex geometries in days, not weeks.

For Volume Production: Our high-speed Precision Stamping presses utilize custom, in-house tooling to produce millions of consistent, burr-free laminations efficiently.

Stacked Electrical Steel Laminations

Material Expertise

We inventory a vast selection of electrical steels, including Silicon Steel (Grain-Oriented & Non-Oriented), Cobalt, and Nickel alloys. We help you select the right grade for core loss and permeability requirements.

In-House Tool & Die

Control your quality and lead time. Our expert toolmakers design, build, and maintain progressive dies in-house, ensuring your project never stalls waiting for a third-party shop.

Value-Added Processing

We go beyond the stamp. Our services include oxide coating, annealing, lamination bonding, and stacking to deliver ready-to-assemble cores.

Lamination Capabilities

Optimized for motors, generators, and transformers:

  • Diameter Range: From miniature components up to 48" diameter segments.
  • Material Thickness: Precision stamping from 0.005" to 0.025" and beyond.
  • Volume: Single prototypes to 1,000,000+ piece runs.
  • Quality: ISO 9001:2015 certified inspection and burr control.
