Manual turntable pneumatic welding machine mainly used for blister packing or high-frequency embossing. Radio-frequency (RF) welding or dielectric welding uses high frequency 27.12MHz electromagnetic energy to generate heat in polar materials, achieving fusing and weld formation after pressuring and cooling. The upper electrode is the welding shape of products, the lower electrode could be the shape of welding products or just a plate. Materials for this high frequency are still PVC or any other materials contains more than 30% of PVC on its surface. Easy to operate,labor-saving and high efficiency.
