The invention relates to a method for producing molded parts, wherein semifinished product is heated in a heating device and is subsequently fed to a shaping machine. The heating device has a closed housing having a door or has a separately closable opening. The heating device optionally has a dividable housing, in the case of which the housing components can be moved away from each other in orderto form an opening and can be moved toward each other in order to form a closed housing. One or more radiant heaters, in particular infrared radiant heaters, are provided in the interior of the housing. Semifinished product is introduced into the interior of the housing and radiant heat produced by the radiant heaters is applied thereto, said semifinished product is heated, and said semifinishedproduct is subsequently removed from the housing. Thermal convection, which is directed substantially upward in the housing, is produced in the interior of the housing. According to the invention, anair flow counteracting the
