A wiring harness is a wiring component connecting various electrical devices in a circuit, and is composed of an insulation sheath, a terminal, a wire, and an insulation banding material. When customizing the Customized Wire Harness processing factory, customers attach great importance to each process of wiring harness processing. Because the meticulous and comprehensive process is directly related to the quality of the wiring harness. Therefore, for an excellent wire harness company, the process of wire harness processing should be comprehensive and meticulous, with strict management to ensure excellent quality. Our company, as a leading domestic enterprise specializing in the production of complex middle- and high-end wire harness products, mainly includes the following processes:

1. Acceptance of incoming materials: Use ROHS instruments to carry out environmental protection tests to test whether all incoming materials required by the harness meet ROHS standards. Equipment required: OHS tester equipment. Process requirements: incoming materials must not contain harmful substances such as lead (Pb), mercury (Hg), cadmium (Cd), brominated biphenyl (PBB), polybrominated diphenyl ether (PBDE), and so on.

2. Line feeding equipment: Put the required processing wire on the transfer line rack. Equipment required: wire feeder. Process requirements: Be careful not to scratch the surface of the wire.

3. Feeding the wire: Put the wire in the wire feeder to fix it. Equipment required: wire feeder. Process requirements: Be careful not to scratch the surface of the wire.

4. Cutting line: Use a cutting machine to cut the wire to the required length. Equipment required: computer cutting machine. Process requirements: It is not allowed to cut the surface of the wire; it is not allowed to cut the copper wire; the error of the stripping length is not allowed to exceed ± 1mm.

5. Wire stripping: According to the requirements of SOP, strip the insulation of the corresponding length of the wire at the joint. Equipment required: Pneumatic peeling machine. Process requirements: It is not allowed to crush the surface; the error of the peeling length is not allowed to exceed ± 1mm.

6. Twisted wire: arrange and twist the conductor at the joint. Equipment required: twisting machine. Process requirements: Do not scratch or scratch the surface of the wire; you must twist the copper wire tightly to prevent loose wires from appearing.

7. Riveted terminal: riveting the conductor and plug terminal at the joint. Equipment required: terminal machine. Process requirements: The terminal is not allowed to deform; it must meet the requirements of tensile force, riveting height, and width.

8. Product assembly: Assemble the plastic plug shell. Equipment required: electric screwdriver. Process requirements: The screws must not be exposed on the surface of the plastic shell; the torque required by the product must be achieved.

9. Continuity test: Use the instrument to conduct the continuity test of the wiring harness. Equipment required: Continuity tester. Process requirements: No short circuit, open circuit, incorrect wiring, poor contact, poor insulation, etc. are allowed.

10. Packaging and sealing: Use plastic bags to seal the finished product of the wiring harness and put it into a carton. Equipment required: sealing machine and baler. Process requirements: The seal should be flat; the packing belt should be tightly packed in the carton, and it is not allowed to fall off.
