Abstract

El objeto de la invención es una formulación, así como un procedimiento de fabricación, de un macho para moldeo en fundición que tiene características térmicas tales que permiten prescindir del manguito aislante y/o exotérmico. Estos machos son térmicamente aislantes y/o exotérmicos y su formulación incluye una mezcla de arena y material aislante y/o exotérmico en forma de microesferas, estando comprendido el porcentaje de material aislante y/o exotérmico en la mezcla entre un 25% y un 75% en volumen, y un ligante.
