HOT RUNNERS | MOULDS


the hot cavity plate into the gate area of the nozzles and prevents crosslinking of the LSR in the cold runner. The Coolshot system is delivered as a complete cold half with pre-installed cold runner system, cooling and complete electric wiring and can be easily integrated into the mould. Ewikon has also developed Smartcontrol, a compact process monitoring and diagnosis unit for hot runner moulds that monitors, analyses and logs all relevant process and system parameters over the entire life cycle of the mould. Data including running times and downtimes of the mould, nozzle and manifold temperatures of the hot runner system, as well as shot numbers, are collected and logged. When defined critical values are exceeded, a warning signal can be triggered. As an option, hot runner system pressures can be monitored as well. The Smartcontrol unit is attached to the outside of the mould or to the wiring box. All data can be exported by using WLAN, Bluetooth, Ethernet or USB. A browser-based user interface allows clear visualisation of the data and can be installed on mobile devices, as well as in company networks. In case of system errors, data can be transmitted to Ewikon for quick remote diagnosis. This allows an early initiation of specific maintenance activities and minimises downtime of the mould. All new hot halves can be equipped with Smartcontrol as an option. Retrofitting the unit to existing moulds is possible as well. SISE has added three new units to its GC range for sequential valve gate control. The entry-level GC Timer can control up to 16 pneumatic or hydraulic valve gates, with the GC Access up to 18, and the GC TECH up to 32 gates. Two are equipped with new colour touchscreens and they all include new functions such as end of stroke management, multi-material management, VNC link, curve displays and in particular the new program- ming mode. In addition, they offer traceabil- ity of parts produced with part counting, scrap detection and real-time data recording. For hot runner temperature control, SISE has also developed a new generation MV3, capable of regulating up to 336 zones. It will be deployed in early 2019 on six platforms (XXS, XS, S, M, L and XL) with four available power cards (2.5 A, 15A, 20A and 30A) to adapt the offer to various industries such as packaging, automobile, cosmetics, medical

and electrical engineering. It will be sold with 10 and 15 inch integrated touch panels and a Linux- based software program developed by SISE. Pivoting and detachable side panels facilitate easy access to power and thermocouple cards. This new model will include advanced functions such as four soft start modes, zone grouping, PTI function for thermocouple anomalies, Moldscan for hot runner system real-time diagnosis, as well as real-time material leak detection. The system is multilingual (up to 12 languages) with unlimited


backup of mould programs. Recording and monitoring temperatures in production,


and communicating via multiple protocols is fully in line with Industry 4.0. SISE has also updated its line of water tempera-


ture controllers with the launch of the 95 E9-45E (90°C). Units offer heating capacities ranging from 9-45 kW, four pump models – 130, 140, 200 and 320 l/min, heat plate exchangers from 60-180 kW and solid state relay as standard. Two heating rates can be used to control the rise in temperature, but also save energy during everyday use. Components are accessible and easy to replace. Other options include multi-protocol communication, tool bleeding, external probe, alarm report, Vortex flowmeter, pseudo-cascade control, external set-point, track measurements and direct cooling. I-mold has developed a range of space-saving tunnel gate inserts, fast high-precision servo motor drives for turntables and indexing plates as used in multi-component injection moulding, and particu- larly rugged hot runner nozzles. The company also offers system solutions for the manufacture and automation of injection moulds, including hot runner nozzles for tight cavity pitches, easy-to-install ‘Fast Half’ systems, and low-height linear actuators
