SHJISCO Cutting Laminations are precision-manufactured to improve the efficiency and reliability of transformers and other electrical devices. SHJISCO supplies Transformer Laminations and CRGO Laminations to help reduce eddy current losses, and also offers Electrical Steel Laminations and Custom Laminations tailored to industry specifications for stronger performance and durability.
Cutting laminations is the process of taking a coil or sheet of grain-oriented or non-grain-oriented electrical steel and cutting it into individual lamination pieces. These pieces are designed to stack with minimal air gaps, forming a solid yet layered core structure. This layered design limits induced current flow inside the core, which reduces eddy current losses and the heat they generate—directly supporting higher energy efficiency.
Precision stacking with minimal air gaps
Tight fit-up improves magnetic core efficiency by reducing flux leakage and supports better mechanical integrity during operation.
Loss reduction & lower heat generation
The lamination structure reduces eddy current losses by restricting induced current paths, cutting wasted energy that would otherwise become heat.
Multiple cutting methods for different needs
Available processing routes include shearing, punching, laser cutting, water jet cutting, and plasma cutting—allowing a practical balance of precision, cost, and throughput depending on your design and order volume.
Material flexibility
Common lamination material is silicon steel, with other options such as nickel-iron alloys or non-grain-oriented steels, depending on application requirements.
For applications that benefit from oriented electrical steel behavior, the page notes key CGO-oriented silicon steel characteristics such as grain orientation along the rolling direction, high permeability, low core losses, magnetic anisotropy, thin gauges, surface insulation coating for minimizing eddy currents, and consistent texture/quality for reliable equipment performance.
