Making its European début on the exhibition stand of Gammaflux Europe GmbH, Wiesbaden/Germany, at Fakuma (Friedrichshafen, 16th to 20th October 2012, Stand 7311, Hall A7) will be the new G24 temperature control system. This high-performance control system unites the compact dimensions of Gammaflux’s LEC controllers with the performance attributes of the TTC models. The G24 controllers also use the Triangulated Control Technology® developed by Gammaflux, a technology that in practical terms means: temperature sensing in 50 ms cycles, temperature evaluation with the self-adapting PID² control algorithm and actuation with phase angle firing control. Further innovations make the G24
· Simpler – the operator can familiarize himself with the working and programming of the G24 controller in just a few minutes; when set to automatic operation, the controller operates in accordance with best industrial practice.
· Less expensive – through the use of fewer electronic components and optimum exploitation of the global supply chain for these components.
· Smaller – each control module is rated for 15 A and up to 24 zones can be accommodated in one single control block. By comparison with the TTC controller, a G24 controller with 128 zones takes up 48% less floor space.
· Faster – the industrial duty USB interface to the screen ensures an update rate of 0.1 sec.
· More flexible – the standard module is equipped with two 15 A outputs which can be used for both hot runner tip and manifold zone control.
Input/output (I/O) interfaces to the injection moulding machine ensure that no reject mouldings are produced and no serious damage can occur to the mould. Thanks to its screen input facility, the G24 software simplifies the interlock between the mould and the machine and also interlock simulation during machine set-up prior to commencement of production. It goes without saying that the new control system features the tried and tested “Mold Doctor® ” functions for mould troubleshooting and for “Performance Monitoring”, the latter serving as a means of detecting leakages and faults in the hot runner system. Every G24 controller comes with a full 5-year Gammaflux warranty.
Application: process temperature control in all areas of plastics processing
For the past 30 years or so, temperature control systems from Gammaflux have been proving themselves in the control and monitoring of hot runner systems in injection moulds. Meanwhile they are also being used in the plastics industry more widely and frequently for the feedback control of process temperatures, typical examples being thermoset moulding, reaction injection moulding (RIM), the processing of liquid silicone rubber (LSR), blow moulding, thermoforming and profile and flat film extrusion. Benno Kippes, Managing Director of Gammaflux Europe, explains: “Just like a hot runner system, each one of these processes requires reliable temperature control. Faults in temperature control can lead to rejects and/or interruptions in production. It is not least for this reason that processors make sure their control systems come from a supplier distinguished by the quality, accuracy and reliability of his products.”
