Our cost-effective unitization process allows for numerous design features, including indexing and multiple-part geometries. Interlocking allows for post-stamping annealing, and while it has limitations in both diameter and stack height, it’s a versatile and efficient way to unitize products.
Our MIG, TIG, pulse TIG, and laser welding solutions can create strong, reliable cores from loose laminations, interlocked sub-stacks, and full interlocked stacks. We can even add vent laminations to improve motor cooling for larger cores. Our welding process allows for post-stamping annealing both before and after welding, ensuring cores are strong, durable, and high performing.
Full Surface Bonding
Laminations made from steel strips are coated with a bonding adhesive. After stamping, the cores are fixed and the adhesive cured with heat and pressure. The resulting cores exhibit unparalleled dimensional characteristics, structural integrity, and feature an interlaminar seal that prevents leakage in liquid cooling applications.
Glue dots, applied as the strip progresses through the die, adhere individual laminations together once they are punched from the strip. This process can limit press speed and reduce the ability to run multi rows, and it does not allow for post-stamping annealing.
