Manufactures advanced technology hot-runner systems specifically for processing engineered materials for automotive, medical and electronics markets. Specializes in micro molding, two-shot, valve-gated and insert molding systems. Direct gating of engineered materials with part weights as little as 0.02 g.
Mighty Tight micro-molding nozzles with pitch centers as little as 7 mm can be valve gated to 9 mm pitch centers. Units feature "no cold slug" edge gated nozzles for medical and automotive applications and mold up to four parts per nozzle with exceptional cosmetics and imperceptible vestige.
Valve-gate systems feature Gate Guardian valve pin guide inserts, which is an extension of the nozzle tip and is the actual gate in the tool that eliminates all wear in the tool. Nozzle inserts can be easily replaced upon wear. Valve pins are adjustable in the hot half.
Novelties included variable-pitch manifolds, mold servo controls, 3D printed plastic mold inserts, and flexible/formable cooling channels.
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.
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.
A new line of hot-runner valve-gate systems designed for high-pressure processes comes from Gunther Hot Runner Systems Inc., W.
A ready-to-go line of hot halves that are fully tested, wired, and ready to bolt onto the mold is new from Gunther Hot Runner Systems Inc., West Chicago, Ill.
As a sign of a growing trend, Gunther Hot Runner Systems, West Chicago, Ill., added to its website (www. gunther-usa.com) a Hot Runner Design Configurator that guides the user through building a virtual hotrunner system online.
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.
The internet is redefining the tool-design process. Some mold designers are finding that using the Web to manage a tool project can shorten lead times, cut costs, and make sure vital data get to all participants in a project.
Ultimate Control for the Toughest Molding Jobs
From complete hot halves to individual nozzles, a host of new products promise smaller gate vestiges, less maintenance, better temperature control, and lower cost.
