Ningbo Yong Source Technology Co. Ltd.   

PVC sealing welding machine: high frequency / high frequency / plastic welding machine (also known as high frequency plastic welding machine), is the first choice of plastic heat sealing equipment, it is the use of high-frequency electric field inside the plastic part of oscillation energy and fusion of various types of products. Working principle: high frequency plastic welding equipment, which belongs to the high frequency dielectric heating equipment. The working principle of dielectric materials, molecular polarization occurs in high frequency electric field, and arranged according to the direction of the electric field, because of high frequency electric field, change direction at breakneck speed, will be due to the dielectric material, dielectric loss and heating. A high-frequency heat sealing machine / machine details are as follows: the full name of "high frequency machine high-frequency induction heating.
