For the personnel related to the production of automobile wire harness industry, they must know the difference between the production process of automobile wire harness and that of ordinary wire harness. Then, for those who have just come into contact with this industry, they may still not understand it. Now, let's take you to understand the difference

1、 Various raw materials

The materials required for general terminal harnesses are only wire rods, terminals and rubber housings. Sometimes there are heat shrinkable tubes, yellow wax tubes and other raw materials. However, there are more raw materials required for automobile harnesses, ranging from dozens to hundreds. In addition to the above, there are also corrugated pipes, black tape, terminal blocks, fuses and other materials. At the same time, there must be some difficulties in processing and assembly

The terminal parts of automobile wires and ordinary wires are also different, so the selection and purchase of their materials should be more strict than that of ordinary harness raw materials

2、 Complex processing procedure

The general processing flow of terminal harness is: wire cutting and head stripping - terminal pressing - tin bonding - rubber housing penetration and other processes. The complexity of the automobile harness production process can be seen from the variety of raw materials. The harness branch becomes the vehicle harness after continuous processing and assembly

3、 Strength of harness manufacturers

The manufacturer of automobile wire harness needs the cooperation of all departments of the manufacturer in the production, and whether it can quickly respond to the customer's urgent needs and meet the customer's requirements. This needs to test the coordination ability and production explosive power of the manufacturer

4、 Technical personnel and R&D capability

When the automobile harness is still in the proofing stage, it is definitely necessary for the automobile harness manufacturer and the automobile manufacturer to continuously conduct debugging and testing until it meets the requirements, and the engineering department and the automobile manufacturer need to constantly communicate. The general terminal harness does not need to be so time-consuming and energy consuming

5、 Certificate Requirements

The system of manufacturing automobile wire harness can be roughly divided into two categories: European and American countries, including China: TS16949 system is used to control the manufacturing process; Mainly Japan: Toyota and Honda have their own systems to control the manufacturing process. There are many manufacturers of automobile wire harness, and it is difficult for many purchasers to distinguish between them. Therefore, TS16949 certification is a good screening method. General terminal harness manufacturers can have UL certification and ISO certification.. VI The production of quality controlled automobile wire harnesses also has very strict requirements on materials, including their electrical performance, material emission, temperature resistance, etc., which are higher than those of general wire harnesses, especially those involving safety, such as the direction control system, brake, and other important components. The general terminal harness must have quality control, but compared with the terminal harness, the quality control of automobile harness production is more strict
