Heat shrink tubing. Before assembling the connector, first insert the heat-shrinkable tube with glue into the end of the wire harness. After the connector is assembled, the heat-shrinkable tube fixes the corrugated tube and the tail of the connector without exposed wires and has a waterproof effect.
Process requirements: When heating the heat-shrinkable tube with glue, the electric heating equipment should be adjusted to 250-350°C, and the processed product should be heated evenly, moving slowly, and should not stay in one place for more than 10s; the heat-shrinkable tube without glue should be baked When heating, the heat gun should be adjusted to 150-250°C, and the processed product should be heated evenly, moving slowly, and not staying in one place for more than 2 seconds. After the heat shrinking is completed, the surface of the heat shrinkable tube is clean, smooth, and free from damage, cracks, wrinkles, bulging, and edge warping at both ends. Pull one end by hand without displacement, disengagement, and exposed terminal crimping parts.
Make labels. Paste a PET self-adhesive name label on the end of the wire harness; paste a paper label on the plastic bag and carton after the wire harness assembly is packaged; print the two types of labels with a printer and paste them.
Process requirements: When pasting, the wide edge of the label is parallel to the wire harness, and the label is not skewed. Overlapping label edges are aligned and the label is flat. The pasting action is completed at one time, so as to avoid uncovering and pasting again if the position is found to be improper during the pasting process. The surface of the label is flat, without wrinkles, warping, etc.
