Wiring Harness Quality

This is a quality control process during the wiring harness assembly process, so I simply ensure that the branch and cable tie dimensions for each harness are correct. Based on the drawings, JinHai has six inspectors: one for incoming material inspection, three internal inspectors for production steps, and two inspectors for the final product. All incoming raw materials, including terminals, connectors, and wires, are inspected according to international standards of AQL 6.5. Every step, including plugging, cable tie attachment, and branch attachment, is thoroughly inspected. The dimensions of each harness are 100% checked. Monthly quality review meetings are also held to identify issues and develop plans, using tools like 8D reports, PDCA, and FEMA.

This is the quality control process for raw materials. We must ensure that each material is correct and the dimensions are correct. We use micrometers, calipers, and 2D projectors to ensure the dimensions are correct according to the raw material drawings. Therefore, during the raw material inspection process, we use a variety of inspection tools to measure and record the raw materials.

This is quality control during the crimping process. Our workers ensure that the dimensions and angles of the crimped terminals are correct. This quality control process is crucial before assembly. We ensure that every step is correct and every detail adheres to your drawings. This quality control process takes place before assembly. For subsequent assembly, we ensure that each terminal and wire are crimped according to the drawings. All semi-finished products are stored on-site, with the terminals protected by dedicated terminal cups. This is quality control during assembly. Our workers place the crimped wires on a dedicated mobile tooling board. The drawings on the board are compared 1:1 with the actual product to ensure no deviations. Every branch size and cable tie positioning are 100% verified upon completion to ensure that every dimension meets the drawing requirements.

This is the quality control process for the final product. This process is very important before the order is packed, so we only need to ensure that every detail, including branch size, wire sequence, terminal plug-in status, drawings, material usage and the entire size are 100% based on the drawings. We also make a quality control report for each batch of wire harnesses, so we only need to confirm the size and material, function, size and requirements of all accessories are in line with your order.
