Abstract

PURPOSE:A plurality of couples of cathode and anode are equipped on the inner surface of cylinder in the plastic molding machine having a screw in opposite positions to each other to measure the changes in dielectric constant of molding material, thereby tracing continuously the degree of mixing and melt viscosity. CONSTITUTION:A molding material such as powder of vinyl chloride resin is charged from hopper 7 and molten and mixed under heating by using screw 1 and cylinder 2 and then extruded from die 11, wherein the dielectric constant of the molding material is measured by using a plurality of couples of anode and cthode equipped on the inner surface of the cylinder 2 and a dielectric constant detector connected with these electrodes.
