TECHNOLOGY | HOT RUNNERS
created nozzles for a 45-degree gate to produce conical parts as well as multi-tip nozzles for small parts that are gated with several gating points. Thermoplay sees 3D printing as an option for fast delivery times and is introducing a new multi-noz- zle with an additively manufactured collar. Gammaflux offers hot runner temperature
control technology and has developed Triangu- lated Control Technology for up to 192 zones, with the G24 being the most popular temperature controller.

hot runner system, which enables the use of smaller injection moulding machines, fits a maxi- mum plate thickness of 240 mm. This allows perfectly symmetrical systems with up to 8 plus 8 drops to be supplied, with a minimum pitch between cavities of 65 mm and between nozzle and inlet of 120 mm. Companies in the Molding Solutions business
unit of Barnes Group have announced various product developments. Synventive has developed a new electric valve gate, the compact eGate Sync, which will complement the legacy eGate system. The company says that the cost-effective eGate Sync has plug-and-play installation and a simple user interface. Quality is improved by increasing shot-to-shot consistency. New hot runner and control technologies for multi-cavity applications are now available from Männer, which is expanding its Packaging and Slimline product ranges with additional valve gate nozzles. The Packaging range for high-speed moulds is complemented by the MCN-EP, with a small diameter and permanently centred valve gate pin. The design of the nozzle tip facilitates high- precision gating and enables the correction of tip protrusion without reworking. Like the proven MCN 8 and MCN 6.5, the new MCN 5 valve gate nozzle from the Slimline series is ideal for tight installation conditions in high-cavity moulds. The company says that it not only has the nozzle in mind, but also the optimisation of the manifold. A 3D printed manifold designed using artificial intelligence can show how the design of flow bore helps a non-symmetrical 6-drop hot runner system achieve perfect balancing. Thermoplay has added two nozzles to its TFS series – the open nozzle series for side injection – for larger part volumes. The company is also targeting special applications. For example, it has

Molding Solutions says that adding digital intelligence to high-precision mechanics is a high priority. When processing PCR and bio-based materials, injection moulders struggle with material fluctuations, which makes process-reliable produc- tion difficult. The Fillcontrol process monitoring system from Priamus identifies and corrects material fluctuations that contribute to decreased quality through dynamic process control by adjusting the manipulated variables of pressure and temperature signals. The development of Foboha’s 48-cavity mould
was the result of focused efforts to produce the best design of a high-cavity hot runner system in terms of balancing and energy efficiency. Each cavity has been equipped with a Priamus sensor to offer complete system monitoring and optimised use of the Priamus process control system. Finally, Molding Solutions has established the
hotrunner.shop, offering 3D data within minutes. With the new hot runner configurator, 3D data of 2-, 4-, or 8-drop hot runner systems with nozzles from Männer and Synventive can be created within minutes. The step-by-step configuration can draw on a material database of more than 12,000 resins. Customers can generate customised 3D data easily and quickly through the application check, which includes a follow-up with an application engineer for applications outside of guidelines. Synventive and Männer configurators are currently available, with Thermoplay to be added shortly.
