    • PROBLEM TO BE SOLVED: To provide a manufacturing method of a resin molded article capable of more uniformizing the mutual mixed state of resins by the combination of the specific resins and a plasticizer. SOLUTION: After a composition comprising a first resin becoming a main component, the second resin mixed with it and the plasticizer capable of swelling at least the second resin is kneaded under heating, the kneaded composition is extruded into a predetermined cross-sectional shape to obtain an extrusion molded article. In this manufacturing method of the resin molded article, the prescribed swelling time of the second resin calculated on the basis of pulse NMR when the second resin is swollen at 30°C using the plasticizer is set to 25 min or below.

    • PURPOSE:To mold a film with projection in good efficiency, by forming the film from the molten resin extruded into the conical gap provided to the inside of a die while instantaneously emitting the molten resin flowed into a manifold through branched orifices from said gap by applying high pressure to said resin. CONSTITUTION:A film is formed to the outside of a rod shaped object moving toward a resin outlet 10 from the insert orifice 4 of a mandrel 2 by the molten resin emitted from the resin outlet 10 of a die lip 9. In this case, when the plunger 22 of an emission pressure imparting mechanism 20 is advanced to impart high pressure to the molten resin accumulated in the manifold, the molten resin within the manifold 12 is instantaneously ejected through the resin outlet of the die lip 9 and expanded out along the opening edge of the resin outlet 10 and projections 32 can be formed to a resin film 31.
    • 目的:通过将熔融树脂的熔融树脂成形为设置在模具内部的锥形间隙中,同时通过施加从所述间隙的分支孔流出的歧管瞬时发射熔融树脂, 对所述树脂的高压。 构成:通过从模唇9的树脂出口10排出的熔融树脂,从芯棒2的插入孔4朝向树脂出口10移动的棒状物体的外部形成膜。在这种情况下, 排出压力赋予机构20的柱塞22前进,对积聚在歧管中的熔融树脂施加高压,歧管12内的熔融树脂通过模唇9的树脂出口被瞬间喷射,并沿着开口 树脂出口10的边缘和突起32可以形成在树脂膜31上。
