30KW /400KHz or 800KHz Ultra-High Frequency Induction Heating Hardening Machine adopts inverter technology, with German IGBT as the power driving parts, three circuit oscillating current, the output frequency of the device can reach 400Khz or even can higher to 800khz with high power output rate and stable performance. Because of Its very high output frequency, 30KW /400KHz or 800KHz Ultra-High Frequency Induction Heating Hardening Machine can heat very small fine metals size same as hairs or thin as 0.1mm to achieve rapid surface temperature rising and fast heating, and get the good uniformity and less oxide layer. It is suitable for processes with high requirements such as fine metal quenching like watches, jewelries and glasses frames etc.
