Abstract

PURPOSE:To provide a molded product which contains no bubbles and has high quality, by moving heated and softened tablets to the pot of a mold without deforming the tablets in a molding machine which is used to manufacture a resin-molded semiconductor device or the like. CONSTITUTION:After columnar resin tablets 1 are heated on a pair of roller electrodes 8, the tablets are caused to slide on the roller electrodes into a cylindrical housing guide 20 provided with a shutter 21 at one end. The guide 20 is turned by 90 deg. so that it is vertically erected. In that state, the axes of the columnar tablets 1 are vertical just like that of the pot 6 of a mold 5. A cylinder 14 is moved straight to a moving plate 15 and stops in a prescribed position. Another cylinder 23 is actuated to position the tablets with regard to the pot 6. The shutter 21 is opened so that the heated tablets 1 contained in the housing guide 20 gravitate into the pot 6.
