What are the different processes involved in automotive wire harness manufacturing, and which one is the best?

The second workstation after wire stripping is the crimping process. Crimping parameters are confirmed based on the terminal type specified in the drawings, and crimping operation instructions are created. Special requirements should be noted in the process documents and operators should be trained. For example: some wires need to be inserted through the sheath before crimping; they need to be pre-installed and then returned from the pre-installation station for crimping; piercing crimping uses special crimping tools, and this crimping method has excellent electrical contact function.

Next is the pre-installation process. First, pre-installation process operation instructions must be prepared. In order to improve the overall assembly efficiency, pre-installation workstations are set up for complex harnesses. The rationality of the pre-installation process directly affects the overall assembly efficiency and reflects the technical level of the process personnel. If the pre-installed parts are too few or the wiring path is unreasonable, it will increase the workload of the overall installation personnel and slow down the assembly line speed, so process personnel must frequently stay on-site and continuously summarize.

Automotive Wire Harness Factory The final step is the overall assembly process. Assembly jigs can be designed based on the assembly panels designed by the product development department, along with tooling and material box standards. The numbers of all installed sheaths and accessories are affixed to the material boxes to improve installation efficiency. The installation content and requirements of each workstation are compiled, and the entire assembly workstation is balanced to prevent a situation where the workload of one point is too large, slowing down the entire assembly line speed. To achieve workstation balance, process personnel must be familiar with each operation and calculate the working hours on-site, adjusting the installation process as needed.

Wire Harness Production mainly uses two methods: terminal pressing (crimping) and forming. There is no single 'best' method; it depends on Wire Harness the functional requirements.
