Function principle of the HPS I system

In contrast to externally heated systems where the heat required in the hotrunner is introduced indirectly from the outside the EWIKON HPS I system works with direct heating located in the melt flow. The system operates on 5 V. Depending on the current, the heater rod in the center of the hotrunner  heats up continuously over the complete length. Around the heater rod the plastic melts and freezes again at the wall of the channel thus insulating and sealing the system. As this frozen plastic layer has excellent insulating properties, the manifold plate hardly heats up, the temperature stays at around 40 ° to 60 °C above the mould temperature. Therefore the EWIKON HPS I system is designated "cold" hotrunner system. This principle of conductive heating is applied in all components of the hotrunner system. Therefore the heat is generated continuously from the connecting nozzle to the injection point.
