Description

Technical Field

[0002] During the production of wire harnesses, thermoplastic processes are used to coat the ends and connections of the harness to prevent damage and improve durability. Current molding processes often utilize thermoplastic molding. High-temperature hot air is used to heat and purge the connector sleeve, causing it to shrink and tightly coat the ends and connections.

[0003] After testing, it was discovered that the main problem with current thermoplastic molding equipment is the cylindrical air outlet structure. This structure often requires adjusting the angle of the wire harness when heating the sleeve to ensure uniform heating and stable contraction in all directions, thereby ensuring a good seal. However, due to the excessive length of some wire harnesses and the high torsional stiffness of the outer material, rotation is difficult. This not only increases the operator's workload and affects the molding effect, but also requires a high level of operator experience. Incorrect operation often causes defects, affecting product quality, and cannot meet current production needs. Utility Model Content
