Electrical Steel Laminations: Laser Cutting & Precision Stamping
The foundation of efficient motors and generators. Sotek is a premier manufacturer of electrical steel laminations, offering a seamless transition from prototype to high-volume production. Whether you need a single laser-cut rotor prototype or millions of stamped stator laminations, we deliver ISO-certified precision from our U.S. facility.
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.
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.
