Drawing

Annealed wax coated Copper Wire of 8mm dia is imported and drawn in the drawing machines through polished tungsten carbide dies and Diamond dies for reduction of the cross-section step by step till the desired dimension is obtained.

Annealing

The Copper Wire becomes undesirably hard on drawing. For restoration of the ductility, the wires are annealed continuously by passing through electrically heated tubes in thermostatically controlled overhead furnaces maintained at a temperature of 500°C to 800°C depending on the size of the wire.

Enameling

Suitably annealed and thoroughly cleaned copper wires are then conveyed to the enameling plants where enamel varnish is applied by passing the wires through containers of enamel varnish and a number of dog-house enameling Dies / Felt and baked in the electrically heated and thermostatically controlled vertical / horizontal furnace. Properly cured enameled wires after coming out from the furnace are wound on appropriate Plastic bobbins and tested each and every product taken in each bobbin. The entire enameling process is automatic.
