PURPOSE:To simultaneously produce moldings of different kinds and regulate the production quantity of each system independently so as to prevent the operation loss by dividing the base polymer flow into two or more sets of systems and performing on each system independently additive injection and extrusion molding. CONSTITUTION:A base polymer extrusion passage 2 of a large-sized extruding machine 1 for base polymer is divided into branched extrusion passages 21 and 22, which are provided with small-sized extruding machines 31 and 32 for additives, static mixers 41 and 42 and dies 61 and 62. The flow rate of base polymer, the kind and injection quantity of additives and the like in each of the branched passages 21 and 22 can be set by a regulating means such as a valve completely independently of each other. |
