Abstract

PURPOSE:To permit molding by extruder satisfactorily while keeping the temperature of resin uniform by providing a given melting acceleration part, a given mixing part, and a given melting end part between a supply part beginning with the material charge port of an extruder screw and a final weighing part. CONSTITUTION:The particles group of nonmolten resin 1 which is not destructed in a melting acceleration part A and has a temperature higher than the secondary transition point but just below melting point is flowed into a mixing part B, where it is uniformly dispersed and mixed in a great amount of melt by means of an auxiliary stirring mixer, e.g., beat, pin, etc., and its partial surface layer enters each inflow side groove of a melting end part C. The resin flow coming to the flow path C reaches through a comparatively narrow aperture delta to a neighboring flow path f. Since, in the process, a temporary but effective shearing force is produced only in nonmolten resin having a considerably great visco-elasticity, particles are deformed and stretched thinly and at the same time are exposed to a frictional heat produced, whereupon its melting point is exceeded at one time to complete melting.
