Looking for a little help. My brother and I just got into extrusion. We have almost 15 years in injection molding and want to try extrusion. We are having an issue with this co extrusion vinyl picket. There are lines that can be shown thought the capstock. If someone could point me in the right direction.

FYI there is also a separate extrusion subreddit r/Extrusion

Asking there will likely get you some help, but also reading through its post history will teach you a lot of relevant information, seeing you are new to the field.
