NPE 2009 Wrap-Up: New Machinery for Thermoforming
NPE had its share of innovations in thermoforming, notably a new machine that opens the small-bottle market to thermoformers. New trim stations offer more in the way of output and versatility. And more machines are now outfitted with off-the-shelf controls to facilitate servicing. A line of formers from Australia also arrived in the U.S. (Note: additional NPE thermoforming news appeared in May and June—see Learn More box.)

Plastics Technology, Refocused
What’s new?

Servo Robots Show More Speed, Muscle & Brains
The recent NPE 2009 show in Chicago saw the debut of dozens of new and enhanced robots for injection molding. The vast majority of the new models were all-servo types, though some economized by mixing servo and pneumatic axes. These new robots emphasized higher speeds, heavier payload capacity, longer reach, and more intelligent controllers that make programming and troubleshooting easier than ever. Telescoping arms and dual arms were very common among the new entries, as well.
