The inventive method for producing a metal-plastic or biplastic article, mainly a bottle capsule, involves placing a metal or plastic blank of an article outer shell into a mould and introducing a die into said blank in such a way that a gap clearance is formed between the die surface and the inner surface of the blank. Then, a melt plastic material is introduced into the thus formed gap clearance so that it is fully filled and the blank is pressed against the mould inner surface. Furthermore, simultaneously, the metal or plastic outer shell of the article is formed, an internal plastic element is produced, placed in the thus formed outer shell of the article and is fixed therein.
Linvention concerne un procédé de fabrication dun article métalloplastique ou biplastique, principalement dun capuchon de bouchage destiné à une bouteille, qui consiste à placer une ébauche en métal ou en plastique de lenveloppe externe de larticle dans un moule de pressage, à introduire dans cette ébauche un poinçon de manière à laisser un espace entre la surface du poinçon et la surface interne de lébauche, puis à injecter dans cet espace du plastique en fusion, à remplir tout lespace avec de plastique et à presser lébauche contre la surface interne du moule de pressage. On forme simultanément une enveloppe externe métallique ou plastique de larticle, et on crée un élément plastique interne que lon dispose et que lon fixe dans lenveloppe extérieure de larticle ainsi formée.
