Based on your previous inquiry about quickly adjusting parameters for hot runner drooling and stringing, the resolution time depends on the severity of the problem. In typical scenarios, it can be resolved quickly:
Minor drooling and stringing: Caused only by slight deviations in temperature and extraction parameters. After following the previous parameter adjustment steps, it can be completely eliminated within 10-20 trial production cycles, taking only a few minutes.
Moderate drooling and stringing: Accompanied by valve needle timing misalignment and uneven localized temperatures. After recalibrating the valve needle closing timing and fine-tuning the temperatures in each temperature zone, it can be stably resolved within 30-50 cycles, taking approximately 15-30 minutes.
Severe drooling and stringing: Caused by hot runner nozzle wear and internal runner pressure imbalance. It requires disassembling and repairing the hot runner or re-optimizing the runner pressure distribution. Repair and elimination can be completed within 1-2 hours.
In most typical debugging scenarios, drooling and stringing can be resolved quickly within half an hour, without prolonged downtime.
