Injection Molding Shrinkage Rate

I measured some parts with similar dimensions to ours and here is a summary of their shrinkage rate.

Mold 1: Pi	Diameter Shrinkage	1.22%	Thickness Shrinkage	3.09%
	Mold Diameter  (in)	Part Diameter  (in)	Mold Thickness  (in)	Part Thickness  (in)
Average	1.997	1.9726	0.09975	0.096666667

Mold 2: Bowl	Diameter Shrinkage	1.99%	Thickness Shrinkage	-3.69%	Support Shrinkage	1.22%
	Mold Outer D (in)	Part Outer D (in)	Mold Inner D (in)	Part Thickness (in)	Mold Support (in)	Part Support (in)
Average	2.48625	2.436692308	2.29975	0.09669231	0.14975	0.147923

Note: Diameter is the outer diameter; Thickness is the thickness at the bowl opening; Support is the distance between the bowl opening and the extruded platform beneath the opening.
Note 2: The thickness varies A LOT around the circle; it could go from ~0.85-1.22in even on the same part
