Cut corrugated tubing, heat shrink tubing, heat shrink tubing with adhesive. The bellows are cut with scissors according to the specifications and lengths required by the process. Heat-shrinkable tubes and glued heat-shrinkable tubes are cut according to the specifications and lengths required by the process, and are cut using a fully automatic computerized tube cutting machine.
Process requirements: Bellows, heat-shrinkable tubes, and glued heat-shrinkable tubes are cut according to the specified size, and the cuts should be neat and smooth without burrs or cracks.

Assemble the harness. Combine the wires according to the drawings and process requirements to separate the first branch wire harness, and then put on a closed corrugated tube (braided mesh) and heat shrinkable tube with glue for wire harness protection, and wrap the branch with tape to fix it; separate each branch wire harness in turn, And wear a closed corrugated tube (braided mesh) and a heat-shrinkable tube with glue to protect the wire harness. The branch is first wrapped and fixed with tape, and finally a wire harness combining the trunk and the branch is formed.
Process requirements: The cutting size of the bellows is the size required by the drawing + the length of the heat shrinkable tube at the branch/2; after the closed bellows at the branch are fixed, the size of the branch point and the size of the wire harness meet the requirements of the drawing.
