Patent

CA 2181327

A foundry mold member made from a plurality of sand particles bound together with a binder which is concentrated at the contact points between contiguous sand particles and consists essentially of gelatins having a Bloom rating less than about 175 Bloom grams. The sand particles are first coated with a sol of the gelatin, cooled to ambient temperature and conditioned to a prescribed water content necessary to effect migration of the gelatin to the interparticle contact points upon heating of the coated particles in a pattern mold.

Composante de moule de fonderie, obtenue à partir de particules de sable agglomérées à l'aide d'un liant, lequel est concentré aux points de contact entre des particules contiguës et est surtout constitué de gélatines de moins de 175 degrés Bloom. Les particules de sable sont d'abord revêtues d'un sol de la gélatine, refroidies à la température ambiante et conditionnées jusqu'à la teneur prescrite en eau, nécessaire pour permettre la migration de la gélatine vers les points de contact inter-particules par chauffage des particules enrobées dans un moule à motif.
