Shanghai QIPANG’s inductive cable preheater machine (industrial frequency preheater) is a professional online heating solution tailored for industrial wire and cable production enterprises. Built on advanced induction heating technology, this equipment is designed for online annealing and preheating of various metal conductors, and can be seamlessly linked with extruders and complete production lines. It effectively solves common pain points in cable extrusion, such as poor adhesion between outer sheaths and conductors, surface gloss defects, air bubbles in insulation layers, and conductor moisture. With CE, SGS and ISO certifications, our industrial frequency wire preheater delivers stable performance in continuous production, making it core equipment for global cable manufacturing facilities.
Adopting the induction heating principle, our cable preheater machine saves more than 60% of electricity compared with traditional oven heating tube equipment. It achieves dynamic preheating temperatures of 0-200℃ and static temperatures of 0-400℃, which can fully dry moisture on the conductor surface, activate the molecular structure of the material, and soften the conductor to optimize subsequent extrusion processing.
The equipment automatically tracks line speed to adjust preheating output, ensuring consistent temperature stability even at different wire running speeds. It causes minimal electrical spark damage to the wire, has low resistance to the preheated conductor, and avoids unwanted stretching of the material during high-speed production, greatly improving the finished product qualification rate.
With precision machining and a compact structure, the preheater is easy to operate and maintain. It supports a wide range of conductor specifications, from 0.3mm iron wire to 5mm stranded copper wire, with multiple models available to match different production needs. It supports 24/7 continuous operation in environments up to 45℃, adapting to the high-intensity production rhythm of industrial factories.
