Abstract

L'invention concerne le moulage d'articles en plastique au moyen d'un moule présentant des régions à parois relativement minces et définissant les surfaces du moule. L'invention concerne également les régions à parois minces en métal en feuille. Les moules peuvent être utilisés dans un procédé de moulage par impression électrique permettant de mouler des produits comprenant un noyau en plastique expansé pris en sandwich entre deux peaux de matériau plastique ou dans des procédés dans lesquels qu'il y a un matériau unique ou un mélange dans la section transversale. Dans un procédé, les articles moulés sont libérés des moules après le moulage mais dans un autre procédé les régions à parois minces sont retenues sur le produit fini, de manière à servir de faces liées d'une seule pièce au matériau plastique sous-jacent.
