How to Maintain Heaters, Thermocouples, Valve Gates and Controls

This article reviews proper procedures and advancements to streamline hot runner system maintenance. Hot runner maintenance has significantly improved with the introduction of threaded nozzles, reducing the risk of leaks and other issues. Although toolmakers initially found threaded systems harder to maintain due to thread damage, advancements in thread design and coatings have mitigated these concerns. Proper support for hot halves is crucial to prevent deflection under cavity pressure. Disassembling hot runners requires careful attention to avoid thread damage, especially for less experienced personnel. Thermocouples and heaters must be handled correctly, with proper labeling and monitoring to ensure accurate temperatures. Valve gates add complexity but can run efficiently with regular maintenance. Read the complete article online at: https://short.moldmakingtechnology.com/Maintaining-heaters
