Lamination Stampings

Arkay Electronic System has recently indented a huge consignment of CRGO & CRNGO Silicon Steel sheets and coils and are totally equipped with new dies and machinery to cut and supply lamination stampings and also torodial cores and mitred strips for transformers. All the stampings will be cut on pillar die sets to ensure zero burrs and the watt losses will be bare minimum and all the CRGO stampings will be Nitrogen Gas Annealed for stress relief. Arkay Electronic System ensures that the quality of the Lamination Stampings will be nearest to the GKW materials and there will be no chance of any sort of complaints in the materials.

Arkay Electronic System has drastically cut the rates due to direct import of raw materials and also due to higher production capacity and factory location being shifted outside octroi limits.
