Abstract
The pattern is surrounded by packed unbound molding medium within a container. The gaseous material resulting from the evaporation of the pattern is removed from within the container as the gaseous material permeates through the packed unbound molding medium. The outflow of the gaseous material is regulated to control the rate of displacement of the pattern by the molten metal. The removed gaseous material is cleaned and cooled, thereby forming condensate and detoxified gas. Thereafter the condensate, and detoxified gas are discharged.
