The raw materials and processing technology of automotive cable accessories have a crucial impact on the quality and safety of automotive cables. The following is an introduction to the raw materials and processing technology of automotive cable accessories:

1. Raw materials

1. Conductor material: The conductor material of automotive cable accessories usually uses copper or copper alloy, because copper has good electrical and thermal conductivity, and strong corrosion resistance.

2. Insulating material: Polyvinyl chloride (PVC) or cross-linked polyethylene (XLPE) is generally used as the insulating material for automotive cable fittings, which have good insulating properties and wear resistance.

3. Sheath material: The sheath material of automotive cable accessories is generally PVC or polyamide, which have good corrosion resistance and wear resistance.

2. Processing technology

1. Conductor production: The conductor production of automotive cable accessories usually adopts the stranding process, that is, multiple strands of thin copper wires are twisted into one conductor to improve the flexibility and strength of the conductor.

2. Insulation processing: The insulation processing of automotive cable accessories usually adopts an extrusion process, that is, the conductor is wrapped in an insulating material, and then the conductor and the insulating material are pressed into one body through an extrusion machine.

3. Sheath processing: The sheath processing of automotive cable accessories usually adopts extrusion process or injection molding process, that is, the insulating layer is wrapped in the sheath material, and then the sheath material is pressed into one body through an extrusion machine or an injection molding machine.

4. Finished product testing: The finished products of automotive cable accessories need to undergo strict testing, including appearance inspection, electrical performance inspection, heat resistance performance inspection, weather resistance performance inspection, etc., to ensure product quality and safety.

The above is the introduction of raw materials and processing technology of automotive cable accessories, I hope it will be helpful to you.
