Tooling innovations at NPE focused primarily on multi-cavity closure and medical applications, though there was also a substantial emphasis on large automotive and appliance parts.
Most of the emphasis is on valve gating and on doing more in less space. Other highlights include standardized mold components, some impressive feats of moldmaking creativity, and advances in mold simulation.
At the world’s largest plastics show in Dusseldorf last fall, hot-runner and controller manufacturers introduced a flood of new developments in speed, size, accuracy, and reliability.
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.
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.
A new modular hot-runner system has a main feed bar that delivers melt to removable and interchangeable sprue and nozzle carrier bars.
The diversity of electric machines will be on display at this year’s show, with several new all-electric versions in direct-drive and belt-driven versions.
