High Frequency induction Pipe Bending Machine is professionaled deisgned and made for the big diameter and big thickness tube. High requency induction pipe bending machine is a kind of hot bending. high frequency Induction heating is the process of heating an electrically conducting object (usually a metal) by electromagnetic induction, through heat generated in the object by eddy currents. An induction heater consists of an electromagnet, and an electronic oscillator that passes a high-frequency alternating current (AC) through the electromagnet. The tube go through the electromagnet to have high temperature, then an hydraulic arm will press the tube to an certain location, final the tube is bent as required shape.
