Abstract

PURPOSE:To endure that only the screw part which requires cooling is effectively cooled while retaining satisfactory extruding properties, by a method wherein a double-wall pipe for cooling and the inside wall of a screw are contacted to each other only at required parts, and other parts are thermally insulated. CONSTITUTION:In the double-wall cooling pipe consisting of an inner pipe 2 and an outer pipe 3, the outer pipe 3 is expanded 4 at the parts where cooling is required (e.g., bent parts) to contact the pipe 3 and the inside wall of the screw 1 at said parts, while at the other parts, the pipe 3 is thermally insulated from the inside the pipe 3 does not contact with the inside wall of the screw. Since only the required parts are cooled, the screw can be cooled effectively without causing any detrimental effect to the resin discharging capability or the like. In addition, the cooled parts can be changed freely and easily by simply replacing the double-wall pipe.
