I.Principle of HF welding machine:
High frequency welding machine
adopts high frequency heating method. High frequency heating can be divided into high frequency induction heating, high frequency medium heating, high frequency plasma heating and microwave heating according to different frequency range. Its working principle is: wood, rubber, synthetic resins and other materials are with high electrical impedance of alternating and direct currents, and their thickness within 0.08-2mm. When they are under the action of high frequency electromagnetic field and certain external pressure, the molecular structure of the material is rapidly destroyed, making the molecules move at high speed and instantly generate heat and weld together. The heating speed is proportional to the high frequency.
II. The application range of hf welding machine is mainly divided into the following categories according to industry:
