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.
A new compression molding compound material combines the light weight, strength, and rigidity of carbon fibers with the flexibility and lower cost of glass materials in a composite compatible with automotive production.
Plastic bearings are real and millions of them are in use doing heavy-duty jobs we used to think only metals could do. Some of Germany-based igus's bearings are traveling around the world as functional parts in a car to demonstrate what they can do.
Baxter showed off his 2.0-derived moves at ATX West this year. The big red guy still looks pretty much the same, but has some new abilities, mostly due to software. The research robot version is now being used in corporate R&D departments as a design platform.
End-production using 3D printing, including objects made of multiple materials in one pass, is getting closer to reality as we saw on the exhibit floor at the recent Pacific Design & Manufacturing Show.
