<p>PURPOSE:To form a profile diameter section such as fine diameter section or the like in a tube and manufacture medical containers of desired shape efficiently in mass production by extruding molten resin out of a mold lip opening to the outside of a mold as tubes and clamping the same by means of a core bar and pressing components and cooling the tubes while the same slide on the surface of the core bar. CONSTITUTION:Resin melted in an extrusion molding machine 11 and a mold 2 is extruded from a mold lip opening 9 to the outside of the mold 2 as tubes 8. The tubes 8 are clamped among the three point of a core bar 3 and pressing components 18, 18 and cooled while being slid on the surface of the core bar 3 and molded as a given molded product 7 with a fine diameter section 19. The fine diameter section 19 of the molded product 7 is cut by a cutter 6 to form molded products 7a having openings 20, 20. An opening component 21 is inserted into one of the openings 20 of the molded product 7a and welded by a high frequency welder or the like to form a welded section 22, while an end section having the other opening 20 is welded by the high frequency welder or the like to form a welded section 23, and lastly a hanger hole 24 is formed on the welded section 23.</p> |
