I. Core Mechanism of Crosstalk Generation Leakage Current Path Coupling: After the heater insulation is damaged, 220V high voltage leaks through the damaged insulation layer to the metal nozzle/runner

I. Safety Preparations Before Testing: Completely disconnect the 220V high-voltage power supply circuit to the hot runner heater, leaving only the low-voltage temperature measurement circuit of the se

I. Minor Leakage (Insulation Resistance 0.5MΩ~5MΩ, Insulation Deterioration Warning) Drying and Dehumidification: Remove the leaking heater from the hot runner and place it in a 150℃ const

I. Prevention During Installation and Assembly Enhanced Insulation: Install a 99.5% high-purity alumina insulating bushing between the heater and the hot runner metal housing to completely block the d
