PURPOSE:To enable to precisely extrude resin, with which powder such as ceramic, metal or the like is mixed, by a method wherein an extrusion nozzle having a structure to form a space, through which hot air or vapor is freely circulated in the interior of the extrusion nozzle, is employed. CONSTITUTION:A space 2, which stands close to the respective portions 11, 12 and 13 of an extrusion nozzle 2, is constituted in the extrusion nozzle 2 and communicates through a circulating port 5 with a tank 3, in the interior of which vapor 4 is introduced. Because the tank 3, which houses fluid such as vapor or the like as heating medium, is directly connected to the extrusion nozzle 1 as mentioned above, the extrusion nozzle 1 can be heated up to a proper temperature and no waste of heat action exists. |
