The improved design not only boosts the efficiency of the machinery, it also enhances the forming method to an unprecedented degree. The increased number of rollers with new break-through friction-free Flowforming method (REPKON patented) has monumental advantages over conventional machines. This revolutionary "Free" Flowforming technology yields free flow of material. INTRODUCING THE NEXT GENERATION FLOWFORMER The six-roller RFFM series flowforming machine can be used as a three roller for small diameter work-pieces as depicted on the table. Alternatively, the fixed roller housing of the...
