Abstract (en)
[origin: WO2004053417A1] A punch (34) and a dice (35) are inserted for perforation in divided chambers (21, 22), respectively, where the chambers are arranged in parallel along a ventilation direction and the insertion is made from one side of openings open at ends in a length direction of the chambers. A thickness (T1) of a partition portion (20) is thinner than that of conventional partition portions, and, even if a fulcrum and a power point of the punch (34) and the dice (35) are not in the same axis in their operation directions, a mold is able to have higher fatigue strength so as to achieve a planned number of times of use. The thickness of the partition portion (20) is set to between 0.4 mm or more and 1.65 mm or less, which is a range to guarantee the strength of the partition portion to prevent its deformation. This enables that, when communication passages are formed in a post-process in a partition portion of a tank produced by extrusion forming, an optimum thickness of the partition portion to be obtained in order to form the communication passages.
