INJECTION MOLDING INSTALLATION AND INJECTION MOLDING INSTALLATION EQUIPPED WITH A MULTIPLE-SCREW EXTRUDER, PARTICULARLY A RING EXTRUDER

摘要

The invention relates to a method and installation for carefully producinginjection molded parts made of thermoplastic materials at high rates. Theinvention also relates to a method and installation for carefully producinginjection molded parts made of thermoplastic materials while involving thesimultaneous homogeneous incorporation of additives or the compounding ofplastic mixtures. Finally, the invention relates to an installation thatenables the continuously running plasticizing step in a multiple-screwextruder (11; 31) to be economically combined with the intermittently runninginjection molding process.
