Right: Mastip’s Open Valve Tip range has been extended and rede- signed to enable insulator caps to clip on while provid- ing precise valve pin guidance to reduce wear and tear at the gate. Tips in G1 and G5 range will have an identifiable groove at the tip end to retain the cap. A new range of Guided Valve (GV) tips, the GVG5, has been developed for precise valve pin alignment to extend production life of the gate
heaters can heat up the nozzle instantly, and Seidel says they use around 60% less power than normal heaters.
Controller evolution Ewikon had several new developments to talk about at the show. Among these is Smart Control, a process monitoring and diagnosis unit that collects temperature data from all areas of the mould, analyses it and logs it. When critical values are exceeded, it triggers a warning signal. It provides improved transparency in moulding operations, since, for example, it can monitor the heat of the hot runners. It has multiple data transfer options over Ethernet of a WLAN, enabling remote diag- nostics. Smart Control fits into the mould hot half. The company also showed its new HPS III-MV multi-tip nozzle, suitable for commodity and engineering thermoplastics. Ewikon says the nozzle, which can be configured with up to six tips, “has been designed as a flexible standardised modular concept.” There are various nozzle body diameters available, as well as different tip insert sizes and nozzle lengths, as well as configuration- specific flow channel diameters. Ewikon has also upgraded its Pro Control hot runner controller, which can control up to 120 zones, depending on configuration. It has an improved touch screen. All controllers feature integrated communication interfaces for easy connection to the injection moulding machine and comprehensive support and error detection functions. The latest update for PSG’s ProfiTemp+ hot runner controller includes a Setup Assistant. This guides the user step by step through the process of setting up the hot runner controller and helps to determine the optimum setting parameters for the new hot runner to be set up quickly. It identifies and analyses the zones of the hot runner in just a few steps and makes suggestions to less experi- enced operators for correct setting parameters,

which they can supplement with their own specifications. For example, says PSG, the Setup Assistant supports zone identifica- tion (manifold/nozzle recogni- tion) and group formation, the operator can define the heating method, and can also define zone names, setpoint values and limit values. At the end, a complete check of the electrical condition of the hot runner as well as the wiring, can be performed and documented, and the
setting parameters saved to the device. PSG is being integrated into Meusburger, which
acquired the company in 2016. But the PSG processes and contacts will not change and it will continue operations at its two Germany facilities. Incoe presented Direct-Flo nozzles with Multip-
ower heating. They have two heating zones but one cable exit under the manifold. New to the range is the DF 18, the largest so far, with a length of 180mm. The smallest is the DF8 and Inco also has a medium-sized DF12. Slim-Flo nozzles, for tight fits in multi-cavity
moulds, are also new. They are based on DF3, 5 and 8 nozzles. Versions based on the DF5 and 8 use special SBH heaters to minimise their outer diameter. Gianpietro Santoiemma, the company’s sales engineer in Italy, says Incoe is looking to expand more into multi-cavity applications; currently, its main emphasis is in automotive. Incoe is also introducing I-Series and I-Series Pro
controllers to the European market. These are already available in the US and in Asia. The larger I-Series Pro, which has a touchscreen interface, handles up to 96 zones.
