Embossed PVC sealer: 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. The PVC and other plastic, placed between the electrodes, and exert a certain pressure, when heated to form after a period of time, and then cooling, it can maintain the plastic deformation, using this characteristic, can realize high frequency or high frequency embossing molding. If two or more than two of the plastic is heated to melt state, after cooling and firmly bonded together, use the
