Abstract

THE PRESENT INVENTION IS TO PROVIDE A TECHNOLOGY, FOR MANUFACTURING RESIN PRODUCTS USING A UNIDIRECTIONAL COMPLETELY ENGAGING MULTI-AXIS EXTRUDER, THAT CAN SUPPRESS DETERIORATION OF QUALITY OF THE RESIN PRODUCTS DUE TO THE DECOMPOSITION OF RESIN BY WAY OF SUPPRESSING THE TEMPERATURE INCREASE OF THE RESIN DURING OF MELTING, AND MIXING AND KNEADING, AND CAN ALSO PROMOTE REACTION OF THE RESIN IN THE EXTRUDER. A SCREW ELEMENT PIECE IS USED, THE SCREW ELEMENT PIECE BEING FOR A SCREW-TYPE EXTRUDER HAVING AT LEAST TWO AXES PROVIDED WITH N THREADS OF SCREWS MUTUALLY ROTATING AND ENGAGING, IN WHICH, IN AN AXIAL CROSS-SECTIONAL VIEW, A APEX OF AT LEAST ONE FLIGHT PORTION PROVIDED WITH N THREADS OF SCREW IS AN ARC HAVING A PREDETERMINED RADIUS OF CURVATURE, AND THE PREDETERMINED RADIUS OF CURVATURE IS DESIGNED SO AS TO BECOME SMALLER THAN A RADIUS OF CURVATURE OF AN INNER WALL OPPOSING TO THE APEX OF THE FLIGHT PORTION IN THE CYLINDER FOR ARRANGING THE SCREW, AND SO AS TO FORM A GAP BETWEEN THE APEX OF THE FLIGHT PORTION AND THE INNER WALL.
