MOLTEN RESIN SUPPLY METHOD AND MOLTEN RESIN SUPPLY DEVICE

Title:

MOLTEN RESIN SUPPLY METHOD AND MOLTEN RESIN SUPPLY DEVICE

Document Type and Number:

WIPO Patent Application WO/2007/105464

Kind Code:

A1

Abstract:

It is possible to stably operate a molten resin supply device for a long time without causing adhesion of a volatile component of the molten resin to convey means. An extrusion unit (4) of an extruder of the molten resin supply device of a compression molding device discharges the molten resin (11) from an extrusion opening (35c) of an extrusion nozzle (30). An air injection nozzle (35) for injecting a cooling gas is arranged on an outer circumference of the extrusion nozzle (30). The air injection nozzle (35) is directed toward the surface of the molten resin (11) extruded from the extrusion opening (35c) so as to cool the surface of the molten resin (11) by the cooling gas.
