Title (EN) INFLATION MOLDING EQUIPMENT FOR PRODUCING CYLINDRICAL FILM
(FR) ÉQUIPEMENT DE MOULAGE PAR GONFLAGE POUR PRODUIRE UN FILM CYLINDRIQUE
Abstract:
(EN) Inflation molding equipment and a process for producing a cylindrical film are disclosed. The inflation molding equipment comprises an extruder for melt extruding a stock material, a single-layer or multi-layer cylindrical die attached to a discharge port of the extruder, and an air ring device for cooling a cylindrical film extruded from the cylindrical die, wherein the cylindrical die has an annular discharge port having an outer diameter of D1, the air ring de-vice is attached on the cylindrical die, and the air ring device has at least one cooling gas outlet port, the cooling gas outlet port having a cooling gas channel defined by an outer circumferential wall having a height of H and an inner circumferential wall having a height; lower than the outer circumferential wall, and D1 and H satisfy a relationship of Q. 5xD1≤H≤1. 5xD1.
(FR) La présente invention concerne un équipement de moulage par gonflage et un procédé pour produire un film cylindrique. L'équipement de moulage par gonflage comprend une extrudeuse pour extruder en fusion un matériau de stock, une filière cylindrique monocouche ou multicouche fixée à un orifice d'évacuation de l'extrudeuse, et un dispositif annulaire pneumatique pour refroidir un film cylindrique extrudé de la filière cylindrique, la filière cylindrique possédant un orifice d'évacuation annulaire qui présente un diamètre extérieur D1, le dispositif annulaire pneumatique étant fixé sur la filière cylindrique, et le dispositif annulaire pneumatique possédant au moins un orifice de sortie de gaz de refroidissement, l'orifice de sortie de gaz de refroidissement comportant un conduit de gaz de refroidissement défini par une paroi circonférentielle extérieure qui présente une hauteur H et une paroi circonférentielle intérieure qui présente une hauteur inférieure à celle de la paroi périphérique extérieure, et D1 et H satisfaisant à la relation 0,5xD1≤H≤1,5xD1.
