Shanghai QIPANG induction cable preheater, also known as industrial frequency preheater, provides professional online heating solutions customized for wire and cable manufacturers.
Adopting mature induction heating technology, this machine is applied to online preheating and annealing of all kinds of metal conductors. It can be perfectly connected with extruders and full cable production lines for synchronous operation.
This preheater efficiently addresses typical extrusion defects, including weak bonding between conductor and outer sheath, dull surface finish, insulation bubbles and damp conductor issues.
Certified with CE, SGS and ISO standards, our industrial frequency wire preheater maintains steady performance during long-term continuous production, serving as essential supporting machinery for cable factories worldwide.
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.
