Based on your previous questions regarding the severity of hot runner drooling and stringing and the relevant background on handling solutions for different scenarios, the resolution time depends entirely on the severity of the drooling and stringing:
Mild drooling and stringing: Caused only by slight deviations in temperature and extraction parameters. After adjusting the parameters, it can be 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 temperature issues. After calibrating the valve needle timing and fine-tuning the 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 runner carbon buildup. It requires disassembly and repair of the hot runner. Repair and complete elimination of the problem can be completed within 1-2 hours.
In most routine debugging scenarios, drooling and stringing can be quickly resolved within half an hour, without prolonged downtime.
