In most cases, 40% rib to wall is a challenge to improving sink when the gates are very far. You can go as low as 26% with a lot care about thin steel condition. Starting at 2/3 rib to wall will cost you some cash as tuning cost, tryout cost, and time. Use proper mold flow analysis is best starting point.
I have to be very critical of videos such as this. The information is very misleading and shallow. Rib geometry is driven by function, period. Tool and processing design can do wonder to reduce or eliminate see through. Material also is a critical player. The issue with the first demonstration part is that those parts are poorly processed on purpose to highlight issues. So, without clarity this can be very misleading.
This is such a fascinating video, its hard to find good injection molding content on youtube. Hope you release more videos.

Where can we find your guide part that seen on video? Very good opportunity to see all these things.
nice one
I think the topic at the beginning is the thickness of the ribs, not draft angles, I guess it’s a slip of tongue.
great
Thank you!!
