Hi all,

New day with new injection molding problem. The issue this time is nozzle plugging, we face this problem during the start-up and sometimes when the machine works in automatic. We have a valve gate hot runner and the material is PA66GF30, for the temperature I work with 290 °C as a maximum in the hot runner system. Yesterday with a mold of 4 cavities and after 4 cycles of production one of the cavities was blocked.
If there are Any suggestions that can help us to avoid this issue, I will be grateful. Thank you!!
