The molding plant (1) consists of a main carousel (2) with a vertical rotating shaft (3) with a number of radial arms that turn about their own axes and have molding shells (5) on their free ends, and a secondary carousel (6) turning about a vertical shaft (7) and having at least two radial containers (8) of powder for transferring to the shells. The plant incorporates a system for reducing the generation of fumes by acting on the gas composition at least in the vicinity of the powder application post. The system for connects the volume between the shell and powder container to a tank containing a gas such as nitrogen for modifying the atmosphere within the volume by partially replacing the atmospheric air. The gas is injected, for instance, via a cloche that covers the assembled shell and powder container. |
