Abstract (en)

[origin: DE10144391C1] Production of molded parts comprises pouring a molding material (F) containing an inorganic binder into a hollow chamber (12) of a molding tool (10) determining the molded part (K) to be produced in a mold blasting machine (1) with the aid of filling elements such as nozzles (8); adding heat to solidify the molding material by removing moisture; and temporarily passing hot gas (L) through the hollow chamber and removing the gas charged with moisture. An Independent claim is also included for a mold blasting machine. Preferred Features: The gas is introduced via the charge opening (11) of the molding tool and removed via the ventilation openings (14) of the tool.
