Re: “Splay” issue on PA66 GF30% with UV stabiliser.
So your 'splay', should be the UV stabilizer being damaged or consumed in the barrel due to the high barrel temps, mold temps, and residence time. I've seen this many times when running UV or FR resins. As long as you can fill the parts, you need to start working the temperatures down until the issue goes away. Either that or run a reverse barrel heat profile. Lastly, get a press with a smaller screw diameter.
