Slitting Coils are narrow-width coils produced by slitting wide electrical steel coils/sheets into accurately sized strips. In transformer and motor manufacturing, slitting quality directly affects downstream lamination stacking, insulation integrity, and overall magnetic performance. SHJISCO provides precision slitting coils using advanced silicon steel slitting technology, delivering tight tolerances and excellent surface quality for demanding electrical steel applications.
If your goal is stable production yield and consistent magnetic behavior, precision slit coils help you control edge condition, dimensional repeatability, and coating protection—so your laminations perform as designed.
CRGO slitting coils are based on electrical steel with a preferred crystallographic orientation aligned along the rolling direction. This enhances magnetic properties in that direction and is widely used for high-efficiency magnetic cores where directional flux is dominant.
CRNGO slitting coils are commonly applied in products involving rotating or multi-directional magnetic fields, such as motors and generators. Slitting quality remains critical to preserve surface coatings and edge condition during stamping and forming.
Choose CRGO when your design benefits from directional magnetic performance (typical in transformer cores and reactors).
Choose CRNGO when your application involves rotating or multi-directional fields (typical in motors, generators, alternators).
In both cases, specify your width tolerance, edge requirements, and coating expectations to optimize yield and loss performance.
SHJISCO’s slitting coil offering is positioned to support magnetic efficiency and manufacturing stability through a consistent set of material and processing characteristics.
High permeability potential: supports efficient magnetization performance in electrical steel applications.
Low core-loss direction: helps reduce energy wasted as heat in transformers and motors.
