Ningbo Yong Source Technology Co. Ltd.   

Plastic sealing edge welding machine: plastic welding machine is the first choice of plastic heat sealing equipment. The main principle of electron tube by self oscillation high frequency electromagnetic field, processed in the upper and lower plastic electrode between the high frequency electromagnetic field under the action of the internal molecular polarization phenomenon, and strenuous exercise to make the plastic self generation of heat, to weld shape in the mold under pressure, the melting temperature is in uniform. Plastic sheet 10% of any PVC content ', no matter how hard it was available, high frequency plastic welding machine heat sealing. High frequency plastic welding equipment, which belongs to the high frequency dielectric heating equipment. The working principle of dielectric materials, in the high frequency electric field
