Car wiring harness is a network main body of car circuit. If there is no wiring harness, then there will be no car circuit. So how is the car harness made? Generally speaking, the wire harness factory is mainly manufactured by three processes: drawing, twisting and coating. If the model standard conditions are more complicated, then its repeatability will be lower. The specific steps, together with the wire harness factory to understand it.

1, coating. Relying on different functional conditions for wires and cables, special equipment is adopted to cover different materials on the outside of the conductor. It can be divided into the following types:

winding: mica tape, non-woven fabric, ribbon paper tape, plastic bags and alkali-free glass fiber tape. In addition to these, there are also fiber materials such as linear silk and cotton yarn.

Longitudinal bag: wrinkled aluminum tape and rubber and other information.

Squeeze bag: lead, plastic, rubber, aluminum and other information.

Dip coating: insulating paint, asphalt, etc.

2, twisting. The twisting process can generally be divided into conductor twisting, weaving, winding, cable forming and steel wire armor and so on. In order to improve the overall degree and softness of wires and cables, more than two single wires can be staggered according to the specified direction, which is called twisting.
