Automotive wiring harness is a network of automotive circuits, if there is no wiring harness, then there will be no car circuit. What is the car harness processing process? The following for everyone to explain in detail:
1, covered. By virtue of the wire and cable is not the same functional conditions, to take a special equipment in the conductor outside the coating is not the same material. Specific can be divided into the following:
Wraps: Mica tapes, nonwovens, ribbon tapes, plastic bags and E-glass fiber belts, in addition to these, there are linear silk and cotton yarn and other fiber materials.
Longitudinal package: wrinkled aluminum and rubber and other materials.
Squeeze package: lead, plastic, rubber, aluminum and other materials.
Dip coating: insulation paint, asphalt and so on.
2, twisted. The twisting process can generally be divided into conductor twisting, weaving, winding, cable and steel armor. In order to improve the overall degree of wire and cable and softness, you can let more than two single lines, according to the provisions of the direction of intertwined, which is called twisted.
3, drawing. Pull the system: single-wire drawing and drawing system. In the metal pressure processing, under the external force value of the metal forced through the mold (pressure wheel), the metal cross-sectional area is compressed, and obtain the conditions of the cross-sectional area of the shape and size of the skills processing method known as metal drawing.
