| 摘要 |
An extrusion molding apparatus (1) for a resin tube capable of increasing the accuracy of the dimensions of the tube molded thereby, allowing the simplification of the structure thereof capable of molding the accurate tube, and allowing the easy molding of the accurate tube, comprising extruders (6, 7) thermally-melting resins (3, 4) to allow extrusion and a die (11) having tube molding passages (9, 10) allowing the molding of the tube (2) by moving forward the resins (3, 4) extruded from the extruders (6, 7) and allowing the resins to pass therethrough. The apparatus also comprises flow control valves (34, 35) capable of regulating the flow rates per unit time of the resins (3, 4) extruded from the extruders (6, 7) to the tube molding passages (9, 10). |
