How is enamelled copper wire made?

All enamelled wires are enamelled on specially developed and produced enamelling machines. The enamelling of the wire is a continuous process consisting of annealing process, enamel coating, curing process, lubricant application, tension control and winding.

0 3

Insulation and Curing: After the enamel is applied, the wire undergoes a curing process, which involves heating it to a specific temperature. This cures the enamel, causing it to solidify and adhere to the wire's surface. The curing process also removes the solvents from the enamel, leaving a continuous insulation layer.

0 4

Cooling and Testing: After curing (and sintering, if applicable), the enameled wire is allowed to cool down.

0 5

Spooling and Packaging: Once the enameled wire passes quality control, it is wound onto spools or reels for storage and transportation. The spooling process is done carefully to prevent damaging the delicate enamel insulation.

0 1

Paying off and drawing: The process begins with the selection of a suitable conductor material, which is typically copper. The chosen conductor is then drawn through a series of dies to achieve the desired diameter (gauge). The wire is cleaned and treated to remove any contaminants from its surface.

0 2

Applying enamel to the wire: Dip and Bake: The wire is passed through a bath of liquid enamel, and then it's heated to cure the enamel, forming a solid insulating layer. Extrusion: The wire is coated with enamel as it passes through an extrusion machine, which forces molten enamel around the wire. The enamel is then cooled to solidify. Spray: Enamel is sprayed onto the wire's surface using a specialized spraying system. The wire is then heated to cure the enamel.
