For the automotive wiring harness production industry, I have a good understanding of the difference between automotive wiring harness and ordinary terminal wiring harness production, but for those who have just entered the industry, I still don’t understand. I will sort out what is the difference between automotive wiring harness production and ordinary terminal wiring harness production. the difference.
Many raw materials
General terminal wiring harness requires only wires, terminals, rubber shells, and sometimes heat-shrinkable tubes, yellow wax tubes and other raw materials, but the raw materials required for automotive wiring harnesses are much more, from dozens to hundreds of kinds. Varying, in addition to the above, there are bellows, black tape, terminal blocks, fuses and other materials. At the same time, there must be certain difficulties in processing and assembly.
Automobile wires are also different from ordinary wires. Most automobile wires are copper multi-core cords, which are as thin as hair, and some have several or even dozens of soft copper wires wrapped in plastic insulated tubes, which are not easy to break. But ordinary wires are copper single-core wires with a certain degree of hardness. The terminal part used is also different, like car wiring harness, you need to purchase original factory terminals. Similarly, the purchase of other materials is more stringent than the purchase of general wire harness materials.
Complex processing procedures
The general terminal wiring harness processing process is: wire cutting and stripping-terminal crimping-tin bonding-rubber shell wearing and other processes. The complexity of the automotive wiring harness production process can be seen from the variety of raw materials. The wiring harness branch is continuously processed and assembled to become the complete vehicle wiring harness.
Manufacturer strength
Automotive wiring harness manufacturers need to be able to coordinate with various departments in the production, and whether they can respond quickly in the urgent need of customers and meet customer requirements. This needs to test the coordination ability and production explosiveness of the manufacturer. Recently, a customer of a mountain climbing car wiring harness urgently needs hundreds of sets of complete vehicle wiring harnesses. We urgently convened the procurement department, planning department, production department, quality assurance department and other relevant personnel to discuss how to solve customer needs. In the end, we decided to reduce the material cycle. At the same time, the planning department and the production department coordinated and sent people to rush the roller-climb harness first, and finally solved the customer's needs perfectly.
R & D capabilities
When the automotive wiring harness is still in the proofing stage, the automotive wiring harness manufacturer and auto manufacturer must continue to conduct reconciliation tests until the requirements are met, and the engineering department and the auto manufacturer must continue to communicate. The general terminal wiring harness does not need to be so time-consuming and energy-consuming.
Certificate requirements
The systems for manufacturing automotive wiring harnesses are roughly divided into two categories: divided by European and American countries, including China: using the TS16949 system to control the manufacturing process; mainly in Japan: such as Toyota and Honda, they have their own systems to control the manufacturing process. There are many manufacturers of automotive wiring harnesses, and it is difficult for many buyers to distinguish between them. Therefore, TS16949 certification is a good screening method. General terminal harness manufacturers have UL certification and ISO certification. Click to view the honor certificate of Jiuwang.
Quality control
Automotive wiring harness production also has very strict requirements on materials: including its electrical properties, material emission, temperature resistance, etc., all have higher requirements than general wiring harnesses, especially when it comes to safety: such as direction control systems, brakes, etc. Harnesses for important components are more stringent. The general terminal wiring harness will definitely have quality control, but compared to the terminal wiring harness, the quality control of the automotive wiring harness production is more stringent.
Having said so much, I believe everyone will also have a general understanding of the production process of automotive wiring harnesses. Only by grasping the differences can we better understand the product.
