Abstract
Since the cross-sectional area of the plastic deforming portion of the extrusion die gradually decreases from the starting end portion toward the terminal end portion, the pressure applied to the molded body in hot deforming is not loosened, hence, the occurrence of cracks can be effectively suppressed.
