Abstract
Un método de hacer moldes, que incluye las operaciones de obtener arena y otro material en partículas a partir de moldes utilizados formados a base de la arena u otro material en partículas, hacer pasar la arena, u otro material en partículas, a un puesto en el que se forman moldes (o partes de los mismos) a partir de ella, y vigilar la temperatura de la arena, u otro material en partículas, en el puesto citado o en su camino hasta el puesto, caracterizado porque se hace que un gas permanente en estado líquido o sólido se evaporice aguas arriba de una región de refrigeración o en la misma, intercambiándose el calor del vapor así formado con la arena, u otro material de partículas, en la región de refrigeración, en su camino hacia el puesto, controlándose el intercambio de calor a fin de mantener la temperatura vigilada de la arena u otro material en partículas a una temperatura máxima elegida es de 40ºC.
