Depending on the grade, barrel heater temperatures went up to 420°C on some of the Teflon plastic injection mold manufacturers' parts, while the tool itself was always at about 160° to 180°C, often using oil temperature controllers.

If you are trying to mould colored parts and are having problems with contamination, you might want to check the hopper and barrel feeder zones. With these temperatures, granules of plastic tend to stick to the hot metal and leave black spots in your parts.

If you still can't get clean parts, it's probably time to pull out the screw and clean it both it and the inside of the barrel with a wire brush while they are still hot of course.

We also mold a really small part with threads at the end of fill which is molded in an insert. Partly because of bad venting and partly because the glass-filled PEEK just doesn't want to fill out those little threads we get shorts that I don't think you'd get with any other material. Also doesn't help that the insert needs sprayed with mold release every few shots or the threaded part will break and stick in the insert.
