Abstract

EQUIPEMENT DE MOULAGE PAR INJECTION D’ARTICLES EN MATIERE PLASTIQUE A PAROI MINCE AVEC UNE EPAISSEUR REDUITE LOCALEMENT L’invention concerne un équipement de moulage par injection d’articles (C) en matière plastique à paroi mince avec une épaisseur réduite localement (A), comprenant un moule (1), un injecteur (5) pour injecter la matière plastique dans la cavité (4) du moule (1) afin de former l'article (C) à paroi mince et un insert annulaire (7) pouvant être, après l'injection, déplacé dans la partie fixe (2) du moule (1) suivant l’axe de l’injecteur (5) entre une position en retrait inopérante et une position avancée pour appliquer une pression de compactage à une zone annulaire (A) de l'article (C).
