Materials Handling: New Equipment Emphasizes Efficiency & Value
Visitors to the recent NPE 2009 show in Chicago were looking for materials handling equipment that could do more than dry, blend, or convey resins. It had to do those things while saving energy, providing faster and easier maintenance, speeding product changeovers, reducing labor cost, minimizing waste, and providing better value for money. The new products cited below addressed those needs and more.

Getting Down to the Nitty-Gritty
Last month in this space I outlined in broad terms the changes we planned for Plastics Technology beginning in November.

Testing & Measuring Instruments: More Versatile, Compact, Affordable
From polymer characterization to on-line bottle or preform inspection, coordinate measuring, and color sensing, new testing and measuring instruments at the NPE show in Chicago were easier to use and more compact, yet often packed higher performance than earlier versions—and sometimes with a more attractive price tag.
