摘要： PROBLEM TO BE SOLVED: To provide a method for manufacturing a molded product such as a core of a reactor having an excellent dispersion state of soft magnetic metal powder in resin, and a reactor.SOLUTION: Resin and soft magnetic metal powder are respectively input from a resin input port and a soft magnetic metal powder input port which are provided for an injection apparatus. The input resin is heated and melted in a heating cylinder, and a complex melt formed by mixing the resin with the input soft magnetic metal powder is prepared. The complex melt is injected into a metal mold to manufacture a molded product. In the present invention, the resin and the soft magnetic metal powder are not mixed in advance but supplied into the heating cylinder or immediately before inputting into the heating cylinder, so that sedimentation of the soft magnetic metal powder due to a difference of density, shape and size between the soft magnetic metal powder and the resin, which could occur by the time when both materials are input into the injection apparatus, can be suppressed, and a blending ratio of the molded product can be maintained, so that variation in the quality of the molded product can be reduced.
摘要翻译：要解决的问题：提供一种在树脂中具有优异的软磁性金属粉末的分散状态的反应器的核心的成型体的制造方法和反应器。溶液：树脂和软磁性金属粉末分别从设置在注射装置上的树脂输入口和软磁金属粉末输入口。输入树脂在加热筒中加热熔融，制备通过混合树脂与输入软磁金属粉末形成的复合熔体。将复合熔体注入金属模具中以制造模制产品。在本发明中，树脂和软磁性金属粉末预先不混合，供给到加热圆筒中，或者在输入加热圆筒之前即可，因此，由于密度，形状的差异，软磁性金属粉末的沉降并且可以抑制在两种材料被输入到注射装置中时可能发生的软磁性金属粉末和树脂之间的尺寸，并且可以保持模制产品的共混比，使得质量的变化的成型品可以减少。
