Show goers will see an electric injection machine in nearly every press maker’s booth this year, and electric/hydraulic hybrids in several.

Although we previewed a number of new developments in hot-runners at NPE 2009 in our May and June issues, the big show in Chicago served up still more new offerings for PET preforms, medical parts, caps and closures, and more.

If a better machine can help your company beat challenging economic conditions, you’ll probably find it at NPE. And finding it will be easier, thanks to our editors’ efforts to sift out of some 2000 exhibits the most significant news in injection and blow molding, extrusion, compounding, and thermoforming.

Yudo Inc., a Korean-based supplier of hot-runner systems, has moved its U.S. headquarters from Newbury Park, Calif., to Columbus, Ohio.

Electrically driven valve pins, a low-cost alternative to valve-gating, mold-mounted temperature controllers, and new components for fast color changes are some of a host of new components and systems unveiled at the giant NPE 2006 show in Chicago this past June. (Some brand-new introductions since the show are also included in this report.) The news includes runnerless products aimed at everything from micromolding to shot weights up to 17.4 lb.

Thermal and mechanical testers, color and appearance sensors, vision inspection devices and CMMs—the NPE had them all in more compact, economical, and easy-to-use models.

Energy-saving all-electric machines will continue to be a big draw at NPE, where new designs or upgraded models will be found in virtually every press maker’s booth.

Closer cavity spacing, in-press serviceability, improved valve gates, smarter controls, quick-ship standard manifolds, and Internet e-commerce were leading themes in hot runners at the big show in Chicago.Hot-runner components were one of the largest categories of injection molding products exhibited at the triennial NPE show in June.
