Abstract

PURPOSE:To provide the injection molded goods of a composite material which are light in weight and are good in electrical characteristics, such as electrical conductivity, and the process for production of these molded goods. CONSTITUTION:The composite material 13 preblended with granules of metals or their alloy having a low m.p. as well as pellets of thermoplastics and additives is charged into a hopper 9. The composite material 13 in the hopper 9 is introduced by a feeder 10 into a cylinder barrel 2 heated by the prescribed amt. each by a heater 14 and while the material is transported forward by a rotating screw 1, the material is kneaded and melted. The molten metal or alloy is lower in viscosity and higher in boundary energy than the molten thermoplastics and, therefore, the state which exhibits a matrix structure and in which the thermoplastics are dispersed in the form of grains or trees is attained. This molten composite material is then injected and packed into a cavity 5A of metallic molds 5 clamped by a mold clamping device 15.
