Why would I go ask Dave D when I have worked in a frisbee factory. Plastic shrinkage has NO effect on how well the mold is packed out though.

HAHAHAHAHAHA...

I think the issue is your assumption on your terminology. With discs, not being packed out would be dips and dents anywhere as well as some curvature on the inside rim wall. But post production cooling (Either table or fixture) has nothing to do with being a whole part.

Again, technically this is the flight plate coming off the shoulder. The rim is technically the wing, which is below the parting line
I mean no disrespect in my comments, just confused on what you are basing your oppinions on. Mine are based on first hand expirience.

No prob.
This is what I am trying to say...
1. Plastics shrink at some point after molding if not in the mold itself.
2. Some plastics retain the shape of the mold better than others.
3. Some plastics retain the shape of the mold nearly exactly, and others do not. Typically, the more premium the plastic the more defined the disc is after molding.
4. Premium plastics discs are so much more defined after molding that they have features (sharp edges, angles, etc) that create more drag than their D/DX counterparts.
5. MANY OF THE MOLDS FOR DISCS IN USE TODAY WERE DESIGNED TO BE USED WITH PLASTICS THAT SHRINK AND DO NOT RETAIN THEIR SHAPE. That is why many of the discs that fly so well in DX/D do not fly nearly the same in the new plastics until they are substantially worn (if ever).
