A wealth of engineering expertise.

Our experience has allowed us to perfect several processes and value-added services to offer the best laminations available anywhere in the world. Plus, our ability to provide customized production to meet individual customer needs is second to none. 

Drawing on nearly 70 years of experience in the laminations business, we’ve honed our skills in materials and tooling design.

  • Slitting

    Slit steel is processed with minimum burr and camber, which are equipped with stripper fingers and hydraulically adjustable carbide knives. Our quick load/unload cart system also allows for faster setup and increased process efficiency.

  • Stamping

    Serving both the motor and transformer lamination markets, Tempel boasts some of the most advanced large progressive stamping capabilities in the world. In addition to a broad range of stamping capabilities, we also run single cavity and multi-cavity tooling.

  • Blanking

    Our universal blank tools support low-volume requirements while our own blanking tool manufacturing capabilities can provide for special design requirements including quality blanks up to 60 inches. In addition to traditional motor blanks, we're skilled at producing segmental laminations for the large power generation market, including hydroelectric generators.

  • Notching

    Tempel produces large diameter laminations for the industrial, hermetic, specialty and traction motor markets, as well as a variety of generator applications. Our advanced automated notching technology gives us the ability to stamp rotor and stator laminations while providing process and cost advantages over traditional manual operations.

  • Helical Winding

    As an industry leader, we're proficient in winding lamination steel strips into an electro-magnetic core. By winding the steel into a laminated core, efficiency is increased, waste is minimized and the steel produces electrical conductivity, enabling the magnetic path to be completed. Thus, generating the maximum amount of power while using the least amount of raw material.

Value-added services to meet your specifications.

In a continuing effort to meet the needs of our growing customer base, we've expanded our capabilities to provide several value-added services.

Annealing

Through our proprietary annealing technology, we can improve the magnetic performance of the lamination, which in turn, improves the performance of the lamination in the final application. Precise, computer-controlled roller hearth furnaces ensure proper grain structure growth for lower core loss and improved permeability. The process also increases inter-laminar resistance by adding an oxide coating and relieves stamping stresses. 

Welding

We offer welding of transformer and motor laminations to create assembled cores of the highest quality. Our process creates a mechanically strong component that eliminates the need for in-house stack and weld assembly. Our robotic welders are also capable of welding silicon and cold rolled steel, either coated or bare. Depending on the customer’s goals, we offer a variety of welds including traditional MIG, TIG, spot and laser welding.

Paper Insertion

As an added value service, our paper insulation service provides welded cores with slot paper installed on a variety of products. The materials range anywhere from Nomex® to Polyester, to a variety of laminated combinations in between.

Epoxy Coating

This unique process for rotors and stators provides excellent electrical slot insulation. The coated areas are protected against corrosion, and heat conductivity from the coil to the iron core is optimized, leading to longer product lifetime. 

Die-Casting

Tempel manufactures aluminum die-cast rotors in both horizontal and vertical casters to a variety of customer specifications. We also offer a variety of finishing operations including ID burnishing and reaming as well as OD brushing, grinding, and machining.

Core Building

Tempel provides value added stator and rotor assembly services for motor and generator customers that want to focus their manufacturing and design resources on other core processes.  These services are down stream of lamination production, which can include processes such as: stator welding; stator cleating; stator insulation paper insertion; rotor shaft insertion; copper bar insertion and more.

Deburr and Recoat

For large generators where high efficiency is required, Tempel removes all burr from the lamination stamping processes with a continuous sanding deburring machine. After the burr is completely removed, we recoat the lamination with insulation material that meets customer’s exacting specifications.
