Hot buttons at the show will be multi-component molding, in-mold labeling/decorating (IML/IMD), in-mold assembly, medical molding, liquid silicone rubber (LSR), micro-molding, and high-speed packaging.

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.

The accepted ground rule for balancing melt flow in multi-cavity injection molds is to achieve equal flow distance from the injection point to each cavity.

A new source of internally heated hot-runner nozzles that eliminate the risk of external heater-wire damage is Melt Design Inc., St.

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.

From complete hot halves to individual nozzles, a host of new products promise smaller gate vestiges, less maintenance, better temperature control, and lower cost.
