Abstract

La présente invention concerne un matériau pour noyaux de fonderie destinés à la fabrication de pièces coulées présentant des espaces creux très fermés, par exemple les canaux de refroidissement des pistons de moteurs à explosion, ce matériau contenant un certain pourcentage de sel soluble dans l'eau et un certain pourcentage de résine synthétique Ce matériau est caractérisé par le fait qu'il contient en plus un granulat métallique. Application à la fabrication de pièces coulées.The present invention relates to a material for foundry cores intended for the manufacture of castings having very closed hollow spaces, for example the cooling channels of the pistons of internal combustion engines, this material containing a certain percentage of water soluble salt. and a certain percentage of synthetic resin This material is characterized by the fact that it additionally contains a metallic granulate. Application to the manufacture of castings.
