Re: Hot Runner-Nozzle Heater
Dear Rick,
Yes. That is actually what is happening. We are also looking for the possibility of suggesting to change the setting to increase the barrel temp instead of the runner heaters.
Yes. The temperature is in Celsius. The setting of coolant for the core and cavity is set at around 25~28 deg.C (chilled water). As for the heat transfer paste, I am not sure if they are using such but I am glad you mentioned it. I will take a sneak peak on their PM process to see if they do.The last time I checked the condition, we have seen no leaking water in anywhere that may close to the heater but we are looking for the possibility of moist (from air) that may develop as heat and very cold medium interacts. Do you think this is reasonable to consider?
Thank you very much!
Sammy
