About TuoCore Magnetics
We manufacture magnetic cores for the power electronics industry: silicon steel wound cores, nanocrystalline cores and ferrite cores. Made to your drawing at ±0.1 mm, samples in 7 days, from single pieces to container-level orders.
Silicon steel wound cores
Toroidal, C-core, stepped JTR, Unicore, three-phase 3D, sensor cores. GOES 0.23–0.35 mm.
Nanocrystalline cores
1K107 ribbon, 18–30 µm, µi up to 100k+, epoxy coated or cased.
Ferrite cores
31 standard types, 413 models — EE5–EE320, pot cores, UU/UI, toroidal rings.
Custom to drawing
Any profile, OD 5–1500 mm, new tooling typically 15–20 days.
How we manufacture
Precision winding of strip to the required shape and dimensions.
Sawing and face grinding for controlled gaps and flat mating faces.
Stress-relief anneal restores permeability and loss after cutting.
Epoxy coating, tape wrapping or PBT casing for insulation.
Core loss, permeability, dimensions and coating thickness verified per batch.
Batch traceability, foam-lined export cartons, palletised on request.
