Electrical Steel Processing

Electrical Steel Processing

Within our facilities, Lamination Specialties is a self-contained provider of raw materials, processes, and services necessary to manufacture finished laminations, slit stock and various value-added services.

Electrical steel processingSlitting

Slitting is the process of reducing Master coils into smaller individual toleranced cuts for further downstream processing into laminations or shunts. Lamination Specialties has multiple slitters with the capability to produce slit coils in thicknesses of 0.007” to 0.060” and widths from 0.750” to 60.000”.


Electrical steel processingCut-to-length

This process converts slit coil into sheets for multiple uses including compound stamping and laser cutting. The coil enters through a leveler to improve flatness and remove coil set. Then, the coil produces cuts in lengths up to a maximum of 120”.

progressive and compound stamping processProgressive & Compound Stamping 

Lamination Specialties has 30+ progressive presses in a variety of sizes and specifications. For this reason, the presses are capable of running a wide range of multi-station progressive tooling for both motors and transformers. Notably, all our presses have precision feeds and advanced leveling capabilities. We offer a range of standard offering parts produced from our own dies.  In addition, we can also run proprietary customer owned tooling.


Robotic welding processWelding

Lamination Specialties has 6-axis robotic capability for both TIG and MIG welding. In fact, robotic technology along with precision fixturing produces a more consistent and efficient weld, providing a better-quality core with tighter tolerances. Additionally, we can provide manual welding for less critical needs or to attach components such as brackets or mountings.

Annealing process of electrical steelAnnealing

Lamination Specialties has two continuous roller hearth annealing furnaces. They run to our engineered specifications to enhance the magnetic and metallurgical properties of the laminations we provide. Notably, our annealing process reduces residual stresses introduced to the steel from the manufacturing process. Additionally, annealing improves the magnetic characteristics of the steel by reducing core loss and increasing permeability.



Tool and dieTool & Die

We have invested in a state-of-the-art tool room and can support both new die building and on-going maintenance. In fact, it could be a simple compound die or an advanced progressive tool with the tightest tolerances and specifications. We are fully capable of adapting customer owned tooling to our presses or in assisting in the acquisition of new tooling from a variety of global sources to meet the needs of customer specifications.


packaging process of electrical steelPackaging

Electrical steel needs special consideration in packaging, handling, and storage. In fact, our storage and handling procedures ensure part quality and magnetic property retention, with careful consideration in placement and loading to minimizing any external stress or damage to packaging.

Proper rotation of stock in our dry, heated warehouse eliminates condensation and reduces the potential for rust formation. We protect each shipment with waterproof paper wrap treated with a vapor corrosion inhibitor (VCI). Our skids are custom-made to properly support and protect our products.

We are capable of shipping either locally or internationally.
