The global new energy vehicle industry expands rapidly, and automotive component factories have purchased a large number of upgraded Single-Wall Corrugated Pipe Equipment to produce flexible threading conduits for wiring harnesses, household appliances and cable protection systems. Market data shows that the compound growth rate of automotive wiring harness conduit market reaches 6.8%, pushing machinery suppliers to improve the automation and energy-saving performance of the production line to adapt to mass vehicle manufacturing.
The extrusion line supports three interchangeable raw materials: PP, PE and PVC, and is equipped with high-efficiency electromagnetic heating components, which reduce heating power consumption by up to 60% compared with traditional resistance heating devices. The multi-channel corrugator mold realizes simultaneous forming of multiple pipes, and the production speed can reach 8–12 meters per minute. The finished single-wall corrugated pipe has excellent flexibility, high temperature resistance and wear resistance, and can be freely bent to adapt to the complex internal wiring layout of passenger cars, heavy trucks and household electrical equipment.
The complete unit is composed of spiral automatic feeder, single-screw extruder, vacuum corrugated forming machine, crawler tractor and fast cutting machine, all controlled by Siemens PLC intelligent system, realizing one-click parameter switching. The quick-locking mold structure shortens the replacement time of pipe diameter specifications to 20 minutes, effectively reducing production downtime for manufacturers undertaking multi-specification orders. In addition to automotive wiring harnesses, the flexible conduits produced can also be used as chemical liquid delivery pipelines and vehicle brake oil pipes, expanding the application scope of the product to multiple industries.
The new generation of equipment adds online visual inspection function to automatically screen defective pipes with cracks and uneven corrugations, reducing the finished product rejection rate to less than 0.5%. Vehicle manufacturers prioritize suppliers equipped with high-speed automatic corrugated pipe lines, because stable conduit quality can reduce the assembly failure rate of wiring harnesses. Industry analysts predict that with the continuous release of new energy vehicle production capacity, the market demand for high temperature resistant single-wall corrugated pipe production machinery will surge sharply in the next three years, and electromagnetic energy-saving heating modules will become the standard configuration of all new production lines.
