In metal pressure processing, the metal is forced through the mold under the action of external forces, the metal cross-sectional area is compressed, and the required cross-sectional area shape and size of the technical processing method is called metal drawing.

According to the drawing process is divided into: single wire drawing and thread drawing.

In order to improve the softness and overall degree of wire and cable, more than 2 single wires are interwoven together in the prescribed direction.

The molding process is divided into conductor molding, cable forming, braiding, wire fitting and winding.

According to the different performance requirements of wire and cable, special equipment is used to coat the outer surface of the conductor with different materials.

1, extruded: rubber, plastic, lead, aluminum and other materials.

2, longitudinal package: rubber, corrugated aluminum tape material.

3, wrapping: ribbon paper tape, mica tape, alkali-free glass fiber tape, non-woven fabric, plastic tape, etc., linear cotton yarn, silk and other fiber materials.

4, dip coating: insulating paint, asphalt, etc
