The invention relates to a method and installation for carefully producing injection molded parts made of thermoplastic materials at high rates. The invention also relates to a method and installation for carefully producing injection molded parts made of thermoplastic materials while involving the simultaneous homogeneous incorporation of additives or the compounding of plastic mixtures. Finally, the invention relates to an installation that enables the continuously running plasticizing step in a multiple-screw extruder (11; 31) to be economically combined with the intermittently running injection molding process.
L'invention concerne un procédé et une installation permettant la production soigneuse de pièces moulées par injection, à base de matières thermoplastiques, dans des rendements élevés. L'invention concerne également un procédé et une installation permettant la production soigneuse de pièces moulées par injection, à base de matières thermoplastiques, avec l'incorporation régulière simultanée d'additifs ou le compoundage de mélanges de matières plastiques. L'invention concerne en outre une installation qui permet de combiner l'étape de plastification en déroulement continu, dans une extrudeuse à arbres multiples (11 ; 31), de manière économique, à l'aide du processus de moulage par injection intermittent.
