Abstract
Before generated air bubbles grow, only the edge of a portion where strength is not to be reduced is locally cooled and solidified to form a wall of fluid. After that, a pin () or the like is pressed into a molten resin portion inside the edge to reduce the volume of a cavity (), thereby reducing the size of generated bubbles. Alternatively, foaming gas is absorbed into resin so as to reduce the volume of generated air bubbles. Thus, a reduction in strength is suppressed.
