Abstract

Un método de fabricación de moldes de fundición o partes de ellos a base de arena refractaria, que comprende hacer pasar arena refractaria, un aglomerante de resina y un catalizador a una mezcladora para formar una mezcla de los mismos que fluya libremente, y formar moldes o partes de moldes de la mezcla, en cuyo método la arena refractaria, mientras se está moviendo desde el recipiente a la mezcladora, por contacto con un medio refrigerante que está a una temperatura de menos de 20ºC o inferior, de modo que se mantenga la temperatura de la arena, al entrar ésta en la mezcladora, por debajo de un valor elegido, en el que el medio refrigerante es un gas licuado, un gas solidificado o el vapor de tal gas.
