METHOD AND APPARATUS FOR EXTRUDING RESIN COMPOSITION

摘要

PROBLEM TO BE SOLVED: To reduce die refuse without generating the shape inferiority such as deformation of a molded product in the extrusion of a resin compsn. SOLUTION: In the extrusion of a resin compsn., a heater 4 is embedded in an extrusion molding die in the vicinity of the leading end part thereof and the leading end part of the die 1 is heated to heat the outer surface of the extruded resin layer 3 passing through the die to temp. higher than that of the resin in an extruder and the extruded resin layer 3.
