Hey new to the business and using a 90ton Toshiba 85x . Shooting ultem material. We’ll long story short Iv been having some issues with the sprue sticking and driving me nuts. Iv tried coming up and down with nozzle temp and the same with the “a” side of the mold. The runner and part are pretty small the runner keeps breaking at the sprue as the mold opens. Job ran fine for two days but today just wouldn’t run: I also thought to purge the barrel incase there was a lot of idle time the material was in the barrel like to much melt time so to speak. Thoughts? Side note can’t use mold release as we are making med device thanks.
