Abstract
A method for producing plastic compound comprises pressure-feeding a resin and an additive therefor into a barrel, and applying compressive force and shearing force on the resin and the additive in the barrel at a predetermined temperature in such a manner that the position of the minimum clearance defined between a bore of the barrel and the maximally diametered portion of a rotor continuously changes with respect to the whole circumferences of the barrel and the rotor, whereby the resin and the additive are uniformly kneaded.
