Abstract

PURPOSE:To obtain such molding as is less in defect of cavity, crack, etc. and not to damage an insert member by incorporating a pressure gauge in a metallic mold, thereby controlling a pouring pressure to molding. CONSTITUTION:A pressure gauge is incorporated in a metallic mold, pressure in the mold is thus measured without changing composition in a thermosetting resin, a pouring pressure is subjected to control for molding, thus obtaining a thermosetting resin composition. A molding with the pouring pressure stepped up gradually is available to preventing a failure of an insert and also an occurrence of cavity and crack. An example is illustrated. In the drawing, 1 indicates a pressure gauge, 2 a molding, 3 a controlling device, 4 a metallic mold, 5 a pouring port of thermosetting resin, 6 a sealing element; a strain-resistance sensitive wire pressure gauge or a transistorized pressure gauge is employed for the pressure gauge.
