Title (EN) EXTRUSION MOLDING EQUIPMENT AND PROCESS FOR PRODUCING CYLINDRICAL FILM
(FR) ÉQUIPEMENT DE MOULAGE PAR EXTRUSION ET PROCÉDÉ DE PRODUCTION DE FILM CYLINDRIQUE
Abstract:
(EN) Extrusion molding equipment produces a cylindrical film comprising (A) an extruder for melt extruding stock material having a cylinder and a discharge port and (B) a single-layer or multilayer cylindrical spiral die attached to port, wherein the die comprises an outer body, mandrel, outer lip, inner lip, and annular discharge port formed between the outer and inner lips, a target value diameter of the cylindrical film of D1, inner diameter of the outer lip of D2, outer diameter of the mandrel of D3, and inner diameter of a cylinder of the extruder (A) of D4, wherein D1, D2, D3 and D4 satisfy the following formulas (1) to (4): D1 = m x D2 wherein "m" is a value in the range of from 1 to 2.9 (1 ) D2 - D3 = 0 to 76.2 (2) D3≥25.1 mm (3) D3 - D4 = 0 to 50.8 mm (4).
(FR) La présente invention concerne un équipement de moulage par extrusion qui produit un film cylindrique comprenant (A) une extrudeuse pour extruder à l’état fondu une matière première comportant un cylindre et un orifice d’évacuation et (B) une filière en spirale cylindrique monocouche ou multicouche fixée à l’orifice, la filière comprenant un corps externe, un mandrin, une lèvre externe, une lèvre interne, et un orifice d’évacuation annulaire formé entre les lèvres externe et interne, un diamètre de valeur cible du film cylindrique de D1, un diamètre interne de la lèvre externe de D2, un diamètre externe du mandrin de D3, et un diamètre interne d’un cylindre de l’extrudeuse (A) de D4, où D1, D2, D3 et D4 satisfont aux formules suivantes (1) à (4) : D1 = m x D2 où "m" est une valeur dans la plage de 1 à 2,9 (1) D2 - D3 = 0 à 76,2 (2) D3 ≥ 25,1 mm (3) D3 - D4 = 0 à 50,8 mm (4).
