High frequency welding and blanking machines are suitable for the working of material from sheet as PVC-PU, synthetic materials and coupled leathers. Thanks to their high precision on working plane positioning, we can weld and/or emboss and also cut with already screen-printed materials. They are equipped with a discharge protection circuit at high sensitivity and protection devices against radio frequency electronic fields. Our machines are available with movables planes or rotating table with various stations, with an electrodes-holder plane predisposed for connection to the cooling unit, and preheater optional.
