From Coil to Core,
In Four Controlled Steps

A linear production flow keeps material traceable and quality measurable at every stage.

01
Material Selection
CRGO coils sourced and verified by grade, thickness and certified loss values.
02
Slitting & Cutting
Coils slit and cut to length on calibrated lines, holding tight tolerances.
03
Stacking & Assembly
Laminations stacked, wound or annealed into finished core geometries.
04
Testing & Dispatch
Core loss and dimensions verified, documented and packed for export.
