The working principle of the MH9548 high frequency splicing machine is to apply high frequency voltage to the joint surface of the workpiece, so that the molecules of the workpiece and the adhesive rotate and vibrate violently. Through intermolecular friction, the workpiece and the adhesive are heated from the inside, and the adhesive solidifies instantly. Since it is bonded by the workpiece itself, not by external heating, it is energy-saving and efficient. It is especially suitable for the combination of doors, windows and frames.
