Abstract: front page image
(EN)Disclosed is a method for producing a perforated hollow tube having a plurality of through holes extending from the outer peripheral surface to the inner peripheral surface, wherein a resin is injected into a mold form comprising a core die for forming an inner space of the perforated hollow tube, and a main die comprising a reference surface for forming the outer peripheral surface and projections for forming the plurality of through holes, the main die being constituted with a plurality of main parts so as to be dividable, and after the resin is cured, the main die and the core die are removed in this order.
(FR)L'invention concerne un procédé de production d'un tube perforé comportant une pluralité de trous traversants, qui se déplient depuis la surface périphérique extérieure vers la surface périphérique intérieure. Le procédé comprend les étapes consistant à : injecter une résine dans un moule comprenant une matrice de noyau pour former l'espace intérieur du tube creux perforé, et une matrice principale comprenant une surface de référence pour former la surface périphérique extérieure et des éléments saillants pour former la pluralité des trous traversants, la matrice principale étant constituée d'une pluralité de parties principales afin de pouvoir être divisée ; après durcissement de la résine, enlever la matrice principale et la matrice de noyau, dans cet ordre.
(JA) 本発明は、外周面から内周面につながる複数の貫通孔を有する有孔中空管の製造方法において、前記有孔中空管の内部空間を形成する中子型と、前記有孔中空管の外周面を形成する基準面および前記複数の貫通孔を形成する凸部を有する、複数の主パーツによって分割可能に構成された主型と、を含む型枠内に樹脂を注入し、この樹脂を硬化した後、主型、中子型をこの順で取り外すことを特徴とする。
