Prototype Services

We’re proud of our manufacturing and processing excellence.

We can review Electromagnetic Finite Element Analysis to offer solutions for optimization of design and material selection based on performance. Our comprehensive list of prototyping services enables us to work with you to build, test and rework your product as needed before it goes to production. 

We offer low volume progressive Stamping - used for prototyping and small production runs, mostly for automotive parts. In addition, our prototyping services use the same materials as large volume production and include:

State-of-the-art Laser Cutting Using a Laser Machine with a Fiber Optic Delivery System

Materials: Electrical steel, mild and stainless steel, aluminum and copper.

Material thickness: From 0.004" [0.10 mm] to 0.50" [12.7 mm]

Material dimension sizes: Up to 120" [3050 mm] x 60" [1525 mm]



Most Advanced Annealing Facilities in the World
Annealing enhances electrical properties of laminations, providing the best performance for minimal cost.

Our precise, computer-controlled roller hearth furnace Annealing facilities allow customers to effectively substitute more favorably priced semi-processed electrical steels for more expensive fully processed electrical steels.

Customer Advantages:

  • Lowers core loss         
  • Improves permeability         
  • Relieves Stamping stress
  • Increases inter-laminar resistance through oxide formation



Precision Welding
Creates a mechanically-robust assembly with smooth clean edges. Our expertise in welding ensures the highest quality of motor and transformer cores.

Customer Advantages:

  • Completed core delivery improves process cycle time
  • Welded components supplied by Tempel reduce equipment and labor costs in customer facilities
  • Completed cores decrease quality issues

MIG Welding
Gas metal arc welding (GMAW) and gas metal arc welding-pulse (GMAW-P) – consumable electrode using a wire feeder.

TIG Welding
Gas tungsten arc welding (GTAW) and gas tungsten arc welding-pulse (GTAW-P) – non-consumable electrode.

Plasma Arc Welding
Plasma arc welding (PAW) - non-consumable electrode.
