Ultra-Long Flexible Induction Coil - High Power Heating Solution from China Suppliers & Factory
Application Scope
Use for large and long metal tube/rod heating process, with multiple winding tubular induction coils to get constant and balanced heating effect.
This ultra-long flexible induction heating coil responds best to huge solid bar stocks and big hollow tubes; moreover, it matches well with irregular shape workpieces. Its flexible property enables its universality, allowing operators to avoid frequently changing coils when processing different shapes of components, which saves time and improves work efficiency.
It saves space in storage and conveyance of the flexible induction coil. Compared to fixed rigid copper tube coils, the flexible coil can match the workpiece with a relatively narrow gap, and the precisely controlled gap can also bestow a better heating performance.
