Key Points for Quality Control in the Stranding Process of Wire and Cable Manufacturing

Those in the wire and cable industry are well aware that the manufacturing process involves numerous steps, but what key points should be noted in each stage? Below are the precautions for the cable stranding process compiled by our team for your reference.

1. Conduct single-wire diameter inspection before commissioning, ensuring the deviation falls within the specified process range;

2. Inspect the single wire for surface quality, ensuring it is smooth, free of oil stains, and free from severe mechanical damage, with no significant oxidation on the copper wire;

3. Inspect the selected press roller, wooden mold, and steel mold to ensure they comply with the process requirements;

4. Inspect the number of strands, arrangement, pitch, and direction of the twisted single wires to ensure compliance with the process specifications;

5. Check the geometric dimensions of the compacted stranded conductor, which shall comply with the specified process requirements;

6. Inspect the appearance quality of the core wire to ensure it is compact and round, free from burrs or sharp edges that could damage the insulation layer, as well as any protrusions or broken single wires;

7. Inspect the single-line connector, which must be welded, and ensure the distance between two connectors is no less than 300mm;

8. Inspect the wiring quality, ensuring it is flat, free of crossings, and without overlapping.
