What is the difference between the production process of automotive wiring harnesses and ordinary terminal wiring harnesses?

For those involved in the production of automotive wiring harness industry, they must understand the difference between the production process of automotive wiring harness and ordinary wiring harness, so those who are new to this industry may still not understand it. Let's take you to understand the difference.

------------------------------------------------------------------------------------------------------

1. There are many raw materials. Generally, the only materials required for terminal wiring harnesses are wires, terminals, plastic shells, and sometimes there are raw materials such as heat shrinkable tubes and yellow wax tubes. However, the raw materials required for automotive wiring harnesses are much more, ranging from dozens to hundreds of kinds. In addition to the above, there are bellows, black tape, terminal blocks, fuses and other materials. At the same time, there must be some difficulties in processing and assembly. Automobile wires and ordinary wires are also different from the terminal parts used, so the selection of materials is stricter than that of ordinary wiring harness raw materials. 2. Complex processing procedures. The general terminal wire harness processing procedures are: wire cutting and stripping-terminal pressing-tin gluing-plastic shell penetration and other processes. However, the complexity of the automobile wiring harness production process can be seen from the wide variety of raw materials, and the wiring harness branches become the whole vehicle wiring harness after being continuously processed and assembled. 3. Strength of wiring harness manufacturers Automotive wiring harness manufacturers need the collaboration of various departments of the manufacturer in production, and whether they can respond quickly in the market where customers are in urgent need of goods to meet customer requirements. This requires testing the coordination ability and production explosive power of manufacturers. IV. Technical personnel and R&D capabilities When the automotive wiring harness is still in the proofing stage, it is definitely necessary for the automotive wiring harness manufacturers and automotive manufacturers to continuously reconcile and test until the requirements are met, and the engineering department and automotive manufacturers need to communicate continuously. The general terminal wiring harness doesn't have to be so time-consuming and energy-consuming. 5. The certificate requires that the systems for manufacturing automotive wiring harnesses can be roughly divided into two categories: divided by European and American countries, including China: using the TS16949 system to control the manufacturing process; Mainly Japan: such as Toyota and Honda, they have their own systems to control the manufacturing process. There are many manufacturers of automobile wiring harnesses, and it is difficult for many buyers to distinguish how to choose from them, so TS16949 certification is a good screening method. Generally, terminal wiring harness manufacturers have UL certification and ISO certification. VI. Quality Control Automotive wiring harness production also has very strict requirements for materials: including its electrical properties, material emission, temperature resistance, etc., which are higher than those of general wiring harnesses, especially those involving safety: such as direction The wiring harnesses of important components such as control systems and brakes have stricter requirements. General terminal wiring harnesses will definitely have quality control, but compared with terminal wiring harnesses, the production quality control of automotive wiring harnesses is stricter.
