Online monitoring of existing systems and configuration and ordering of new molds were featured at K 2019, as were numerous advances in valve-gate controls.
By doubling as a locating ring and housing all the mechanics internally, a new valve-gate system greatly reduces mold-height requirements.
Hot runner system’s nozzles promise a consistent thermal profile and wide molding window without the risk of polymer leakage or accidental cold condition starting.
Automotive was a key focus for hot-runner developments. 3D-printed plastic prototype tools were another highlight.
INJECTION MOLDING AT NPE: Molding Exhibits Show Off Cell Integration with Multiple Processes & OperationsBy: Matthew Naitove - Plastics Technology
If you’re interested in lightweight composites, IML, LSR, multi-shot, inmold assembly, barrier coinjection, micromolding, variotherm molding, foams, energy-saving presses, robots, hot runners, and tooling—they’re all here in force.
Molds that break speed records for specific applications; hot runners for medical, packaging, and automotive parts; temperature and valve-gate controllers; and standardized mold components constitute a large grab-bag of news in the tooling category for injection molding at the Dusseldorf show.
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.
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.
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.
