Look for bioplastics such as polylactic acid (PLA) to make a strong run at polystyrene foam packaging in the next three years. The major reason is significant technology development in screw design that brings productivity rates for PLA foaming more in line with polystyrene systems. David Fogarty, president, Plastic Engineering Associates (PEA) of Boca Raton, FL says he has developed new screw designs that have now been licensed to three companies.
Ability to maintain melt temperature is critical because of the low glass transition temperature of PLA. PEA supplies 4.50″ x 6.00″ (120mm x 150mm) and 6.00″ x 8.00″ (150mm x 200mm) sized Turbo-Screws specifically designed for the bioplastic, and has worked in tandem with PLA Supplier NatureWorks. Output rates are said to be in the 75 percent to 85 percent range of polystyrene output.
This slideshow includes several versions of multi-materials machines, two different composites processes including one at microscale, and two vastly different metals processes. Potential game-changers down the line include three microscale processes.
UL is partnering with metals additive manufacturing (AM) supplier EOS to provide AM training to EOS's customers. It's designed to promote correct usage of AM technologies by OEMs and others in manufacturing.
To commemorate Earth Day, we take a look at the state of ocean plastic. If things don't change, by 2050 the oceans will contain more plastic than fish by weight. Here are the problems, as well as some solutions.
