要約
(EN)
This method for producing a foam-molded member comprises: a first step for arranging a foam-molded first part (11) and a rigid member (3) inside a second-part-molding mold (20), and pressing and fixing the rigid member (3) against the second-part-molding mold (20); and a second step for pouring a second-part synthetic resin material (U) into the second-part-molding mold (20), and foaming and molding a second part (12) that envelops at least a portion of the rigid member (3) and that is integrated with the first part (11).
(FR)
La présente invention concerne un procédé pour produire un élément en mousse moulé, comprenant : une première étape consistant à disposer une première partie (11) moulée en mousse et un élément rigide (3) à l'intérieur d'un moule (20) de moulage d'une seconde partie, et à appuyer et fixer l'élément rigide (3) contre le moule (20) de moulage d'une seconde partie ; et une deuxième étape consistant à verser un matériau (U) de résine synthétique pour seconde partie dans le moule (20) de moulage de seconde partie, et à faire mousser et mouler une seconde partie (12) qui enveloppe une partie au moins de l'élément rigide (3) et qui forme partie intégrante avec la première partie (11).
(JA)
 発泡成形された第1部分(11)と剛性部材(3)とを第2部分成形用金型(20)内に配置し、剛性部材(3)を第2部分成形要金型(20)に押付けて固定する第1工程と、第2部分成形用金型(20)内に第2部分用合成樹脂原料(U)を注入し、剛性部材(3)の少なくとも一部を包み込み第1部分(11)と一体となる第2部分(12)を発泡成形する第2工程と、を有する発泡成形部材の製造方法。
