Meloon Foundries Inc. was approached by a plastic film manufacturer to mold 30 aluminum plenums. The plenums, which were made of SR319 aluminum, were no-bake molded on a continuous no-bake mixing production line, and then shot blasted.

Standard tolerances of +/- .030” were held. The plenums were .125″-.500″ thick, had an outside diameter of 48″ and were delivered ready for powder coating by the customer. Product ranges in size from 24″-60″.
