Jan Schroers, a Yale University materials scientist, is touting a breakthrough that can help metal compete with plastic -- the ability to blow mold metal. The blow molding process has some technological advantages for economically making complex, hollow shapes. Until now, blow molding has been pretty much limited to thermoplastics, because of the unique properties (viscocity, flow strength, etc.) of the material. Schroers, in an article in the journal Materials Today, explains the conditions necessary for blow molding some metals. Registration is required for the article, but for more information I recommend listening to this podcast interview with Schroers, or reading this news release from Yale on his research.
