Abstract

Produit de moulage extrudé à partir de matières pulvérulentes, de section dro te solide ou creuse. Le produit de moulage est obtenu en préparant un pré-moulage constitué par les matières pulvérulentes et ayant un revêtement qui forme ultérieurement la couche interne et/ou externe et qui fond dans un procédé de frittage ultérieur en pénétrant partiellement dans les pores de la zone superficielle du pré-moulage et se soude à celui-ci et en extrudant hydrostatiquement ce pré-moulage après le procédé de frittage.
