摘要： Disclosed is a process for the preparation of a thickness-reduced deep-draw-formed can, which comprises the steps of (i) coating a crystalline thermoplastic resin on a metal plate, (ii) heating the coated metal plate at a temperature higher than the glass transition point (Tg) of the thermoplastic resin and draw-forming the coated metal plated, and (iii) heating the obtained preliminarily drawn cup at a temperature higher than the glass transition temperature (Tg) of the thermoplastic resin and redrawing the cup at a bend-pulling speed of at least 1 m/min. According to this process, damage of the coating layer can be drastically moderated, and a deep-draw-formed can having prominently improved corrosion resistance and heat resistance can be obtained.

摘要： An improvement in a method for producing a welded metallic can body. The method involves holding and pressing a lap portion of the side marginal portions of a can body-like structure, which has been formed by bending a metal blank into a cylindrical shape, along its entire length between a pair of opposing parallel wire electrodes placed on the opposing surfaces of parallel electrodes, and passing an electric current across the parallel electrodes for a predetermined period of time during the pressing to subject the lap portion to resistance welding. At least one of the parallel electrodes is divided longitudinally into two or more portions electrically insulated from each other, and an electric current is passed through at least one of them independently from the other portions so that the temperature rise in the lap portion of the can body-like structure becomes uniform. Also disclosed is an apparatus for producing a welded metallic can body in accordance with the aforesaid method.
