ABSTRACT:
This invention relates to an improvement in the method of manufacturing alate medical needles. The base part of a needle is inserted into a thermoplastic resin tube and the inserted portion is set in a wing-forming mold. The thermoplastic resin is heated to mold wings integral with the tube. Since the molding of the wings and their connection to the tube can be accomplished simultaneously, this method enables high-speed continuous manufacture which is impossible with conventional methods. Heating of the thermoplastic resin is preferably conducted by high-frequency dielectric heating.
