Thermoplay hot-runner systems include hot-runner nozzles, manifolds, hot sprues, temperature controllers with sequential valve/gate control, and complete bolt-on hot sides.
F series nozzle features patented heater design that uniformly distributes heat to the entire nozzle surface. Heater design and selected materials reduce coefficients of thermal expansion between the different metals, which results in 30% less heat required and allows up to 60% energy savings, and better heat profiles.
Standard single-drop nozzles in three styles: Type-1 nozzles used where gate vestige is critical to appearance, or to minimize stringing or drooling; Type-2 nozzles for viscous materials when gate vestige is not critical, or when gating into a runner; and Type-3 valve gate nozzles for highly cosmetic gates, or when higher flow rates are needed. Also offers multigated nozzles (up to eight gates) and hot-edge gated nozzles.
D series nozzles offer beryllium copper cores for heat transfer with a steel tube through the center for wear resistance, while the KS series offers replaceable tips and faster color changes.
TG series temperature controllers offer individual microprocessor control of each zone and come standard with higher amperage for high-load manifold applications.

More productivity with less energy consumption and capital investment; more operations in the machine or manufacturing cell with less time, labor, energy, and capital—these were the common themes of injection molding exhibits at October’s K 2013 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.
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.
There were new presses of all stripes aplenty at K 2010, but the “wow” factor was supplied by automated work cells and integrated manu-facturing systems performing multiple operations before, during, and after molding.
Several new developments include a brand-new compression blow process, the first foamed PET bottles, and a preform decontamination approach for aseptically filled products sold at ambient temperature. Attendees also saw a new stack-mold Multi-Parting Line concept that doubles bottle output within the same machine footprint. (Additional NPE blow molding news appeared in May and June—see Learn More box.)
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 LSR model of Babyplast hydraulic tabletop injection press comes from Cronoplast S.L. of Spain, represented here by Alba Enterprises Inc., Rancho Cucamonga, Calif.
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 high-temperature lubricant for liquid silicone rubber or other thermoset molds, and a new solvent for cleaning between lubrication cycles, come from Alba Enterprises Inc., Rancho Cucamonga, Calif.
Liquid silicone rubber is breaking out of its niche into a broader array of applications, helped by new developments in materials, machinery, and processing. Larger parts, micro-parts, foams, and multi-color or multi-material combinations are key areas of innovation.
A new hot-runner sprue-tip design featuring a single heater rather than a more complex dual heater is new from Alba Enterprises, Rancho Cucamonga, Calif.
What hot runners are to thermoplastics, cold runners are to thermosets like liquid silicone rubber (LSR). Two cold-runner systems for LSR were introduced at this year's NPE show in Chicago.
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.
