The quality of the wire harness is an important consideration for equipment manufacturers when they are looking for suppliers. Choosing an excellent wire harness processing company requires not only the price but also the process of wire harness processing. Because the process is detailed or not, it is directly related to the quality of the wire harness.
The electronic wire harness manufacturer calls an excellent wire harness processing enterprise. The process of wire harness processing should be comprehensive and meticulous, with strict management to ensure excellent quality. As a leading domestic enterprise specializing in the production of complex medium and high-end wire harness products, Jiefuxin has a complete wire harness production process and a strict quality assurance system.
1. Acceptance of incoming materials: Environmental testing is carried out using ROHS instruments to test whether the incoming materials required for all wiring harnesses meet ROHS standards. Equipment required: OHS tester equipment. Process requirements: Lead materials (Pb), mercury (Hg), cadmium (Cd), brominated biphenyl (PBB) polybrominated diphenyl ether (PBDE) and other harmful substances are not allowed.
2. Wire feeding equipment: Put the required processing wire on the transfer wire rack. Required equipment: wire feeder. Process requirements: Be careful not to scratch the surface of the wire.
3. Feeding wire: Put the wire to the wire feeder to fix it. Required equipment: wire feeder. Process requirements: Be careful not to scratch the surface of the wire.
4. Cutting the line: use the cutting machine to cut the required length of the wire. Equipment required: computer cutting machine. Process requirements: Do not cut the surface of the wire; do not cut the copper wire; the length of the stripping error shall not exceed ±1mm.
5. Stripping of wires: Strip the insulation of the corresponding length of the wires at the joints according to SOP requirements. Equipment required: pneumatic peeling machine. Process requirements: The surface is not allowed to be crushed; the length of the stripping is not allowed to exceed ±1mm.
6. Twisted wire: Finish and twist the conductor at the joint. Required equipment: twisting machine. Process requirements: scratches are not allowed to scratch the surface of the wire; the copper wire must be tightened and no loose wire is allowed.
7. Riveted terminal: Rive the conductor and plug terminal at the joint. Equipment required: terminal machine. Process requirements: The terminal is not allowed to be deformed; it must meet the requirements of tension, riveting height and width.
8, the electronic wire harness manufacturers said the product assembly: assembly of plastic plug housing. Equipment required: electric screwdriver. Process requirements: the screws are not allowed to expose the surface of the rubber shell; the torque required by the product must be achieved.
9, continuity test: the instrument is used to conduct the wire harness test. Equipment required: Conduction tester. Process requirements: Short circuit, open circuit, incorrect wiring, poor contact, poor insulation, etc. are not allowed.
10. Packing and sealing: Pack the finished product of the wire harness with plastic bag and put it into the carton. Equipment required: sealing machine and baler. Process requirements: the sealing should be flat; the packing belt should be tightly wrapped in the carton and not allowed to fall off.
