Title (EN) DENSIFYING APPARATUS FOR PLASTICS MATERIAL
(FR) APPAREIL DE DENSIFICATION POUR MATERIAUX PLASTIQUES
Abstract:
(EN) An apparatus for densifying expanded plastics material or other plastics products comprises a chamber (10) having a wall (16) which is cast from metal and incorporates an e.g. electrical heating element (20) cast therein, and an outlet in the bottom of the chamber through which molten plastics material flows under gravity. The wall (16) is coated with a low friction polymeric material.
(FR) L'appareil décrit, qui sert à densifier des matériaux en plastique expansé ou d'autres produits en plastique, comprend une chambre (10) présentant une paroi (16) qui est moulée par coulage à partir d'un métal et dans lequel est incorporé par coulage un élément chauffant électrique (20), ainsi qu'une sortie qui est prévue dans le fond de la chambre et à travers laquelle le matériau plastique en fusion s'écoule par gravité. La paroi (16) est revêtue d'un matériau polymère à faible frottement.
