AI Technical Summary

Technical Problem

Existing nylon tubing is prone to softening and strength reduction under high-temperature conditions, leading to bulging and cracking of the tubing, posing safety hazards. Furthermore, traditional equipment is difficult to meet the performance requirements of high-voltage electric drive systems and battery cooling systems in new energy vehicles.

Method used

The system employs structural components with automatic heating adjustment and feedback mechanisms to detect the viscosity of the nylon raw material and automatically control the heating, ensuring uniform material delivery. Multiple temperature control boxes are used to adjust the fit of various components, achieving precise molding of the nylon tube and preventing collapse. Pressurized nozzles and torsion threaded rods within the gas-filled pipe increase the internal toughness of the nylon tube, ensuring uniform molding.

Benefits of technology

This improved the temperature resistance of the nylon tube, prevented cracking, ensured the uniform thickness of the nylon tube and its stability under high pressure, and enhanced product precision and safety.
