Abstract

Punch tool mfr. in which one or more punch knives are bent to a required pattern. The knives, made from magnetic steel strip, have flanged edges which are placed on magnetic table base which is energised so that flanges are drawn to the table along their entire periphery. Non-shrinking epoxy resin is then moulded to a predetermined distance from the knife cutting edges. The strongly adhering resin hardens while the energising magnetic field of the table base is maintained.
