Anyone seeking to master quality in injection molding production must focus on the hot runner system. Unwanted process variability can be avoided by combining geometrically, thermally balanced systems with high-performance temperature controllers and reliable needle-stem control. 

Multi-Cavity Molds: Hot Runner Technology for Optimal Part-to-Part Consistency 

At this year's Moulding Expo in Stuttgart, Germany, Italian hot runner specialist HRSflow, San Polo di Piave, presented a new family of hot runner solutions for multi-cavity molds. The multicavity series is suitable for the large-scale production of injection molded products wherever short cycle times and high surface quality are specified, for example in medical applications, cosmetic articles, caps and closures, and packaging.

The fully assembled and wired hot runner systems H4016 complete the range of ready-to-install systems and hot halves from Hasco Hasenclever GmbH + Co KG, Lüdenscheid, Germany. They constitute an attractive solution, specially tailored to the market, with all the system components screwed together already.

New Hot Runner Systems Complete the Program 

In cooperation with two new subsidiaries, the Haidlmair Group, Nussbach, Austria, is showing several innovations in the field of hot-runner technology, mold monitoring and lifetime management. FDU Hotrunner GmbH, Frankenthal, Germany, markets the FDU (flat die unit) launched by Haidlmair in 2016, which, according to the manufacturer, is particularly characterized by the fact that, in comparison to circular nozzles, it introduces less shear-induced heat into the melt, shortens the cycle time and reduces the required injection pressure and energy consumption.

For the production of a container for a disinfectant gel precision mold maker Matrix developed a complex 6+6+6-fold 3-component mold. Two single parts are manufactured in one step and sealed in the tool by overmolding with a third component. The demanding mold design which uses two rotating index plates required a tailored hot runner solution which was supplied by Ewikon.

Due to its ability to produce high-precision plastic components, electrically driven pin actuation is increasingly being used in medical, pharmaceutical, and technical fields. For devices that need to be medically certified, component stability and accuracy are particularly crucial to ensuring the safety of drug delivery.

Flexibilization of production, lightweight design, functional surfaces, increasing product customization, consistently low reject rates etc. ¿ the OEM wish list is becoming longer and longer. While the OEMs are the main drivers in the injection molding segment, their mounting demands are challenging Tier 1 suppliers, mold makers and systems suppliers alike. For an interview, we met with specialists from GKTool and HRSflow, for whom the search for new solutions is daily routine. The topic is integration ¿ of ideas, processes and system partners.

"With System Integration,  Fewer Errors Occur" 

Moldmaster uses thermoanalysis to identify melt leakage in the manifold outlet.

A special feature of its TempMaster temperature control units is the innovation presented by Mold-Masters. According to Hans Hagelstein, President Europe, Middle East, Africa and India Mold Masters, the globally active supplier of hot runner systems, controllers, add-on injection units and co-injection systems is the first company in the industry to use thermoanalysis to identify melt leakage in the manifold outlet.

“This innovation saves injection molders considerable repair costs and downtimes,” says Hagelstein. To activate this monitoring function, thermocouples are installed at various points in the manifold. According to Hagelstein, “The size of the manifold determines how many thermocouples are required for identification, and the position of the individual thermocouples determines how quickly the leakage is recognized. In internal tests on this function, leakages were quickly and reliably identified before damage could occur.” The manifold leakage detection is optionally available for all hot runner temperature controllers TempMaster M2+ and M3. The original function for rapid detection of leakages within the nozzle recesses is standard for all M2+ and M3 controllers.

The M3 has additional appeal thanks to the so-called TC-Connect technology. “On the mold, we mount an eBox, which is connected to the M3 control unit with a single data cable. In this way, the demand for conventional TC cables for the individual thermocouples is completely eliminated,” explains Hagelstein. A considerable proportion of costs can thus be saved and the injection molding cell made tidier, since these cables make up about half of the mold wiring. The wiring of the hot runner system remains unchanged.

In addition, Mold-Masters has long been concentrating on increasing production efficiency and part quality in PET preform production. The company is introducing its iFlow distribution technology. For this, the company introduces its iFlow manifold technology. iFlow manifolds consist of two steel-block halves, which are brazed together after the melt channels have been CNC-milled and polished in both parts – with a material-friendly geometry that is optimized to the application. “For this purpose, we have introduced a new PET nozzle series with improved thermal profile and locally exchangeable heating sleeve. These nozzles are also equipped with the MasterShield technology, which ensures better leakage protection between the nozzle and the manifold even with a cold start,” adds Hagelstein.

The hot runner system is marketed under the name PET series. According to the manufacturer, it should be possible to produce preforms with lower wall thickness, save material due to better hot runner balancing and lower fluctuations of the part weight, and shorten the cycle time with a faster filling phase and a wider process window – the latter resulting in a reduction of the acetaldehyde (AA) content.

It sounds a bit like an all-singing, all-dancing solution – but the many examples in this text bear witness to this: customers expect nothing less from their hot runner suppliers.
