What is the process flow of wire harness production

The first workstation for wire harness production is the wire opening process. The accuracy of the production process is directly related to the entire production progress. Once errors occur, especially when the production size is too short, it will lead to rework at all workstations, which is time-consuming and labor-intensive and affects production efficiency. The second station after starting the line is the crimping process. The crimping parameters shall be determined according to the terminal types required by the drawings, and the crimping operation instructions shall be prepared. If there are special requirements, the operators shall be noted on the process documents and trained.

Next is the pre assembly process. Firstly, a pre assembly process operation manual needs to be prepared. In order to improve the overall assembly efficiency, complex wiring harnesses need to be equipped with pre assembly stations. If there are too few pre assembled parts or the assembly wire path is unreasonable, it will increase the workload of the overall assembly personnel.

The final step is the final assembly process. According to the assembly platform designed by the product development department, design tooling equipment, material box specifications and dimensions, and label all assembly sheaths and accessories on the material box to improve assembly efficiency. The electronic technology content and quality of electric vehicle wiring harnesses have gradually become an important indicator for evaluating the performance of electric vehicles. Electric vehicle manufacturers also attach great importance to the selection of wiring harnesses, so it is necessary to understand the process and production of electric vehicle wiring harnesses.
