Gemini Plastics, Inc.: We have more whitening, only around the sprue area of our part, when molding PET bottle grade virgin. The rest of the part looks great but the area of about 1-2" diameter around the single center sprue has blush/whiteness. I know PET has to cool quickly to stay clear and the water is at 50F so we have the cooling in line.
Any suggestions would be welcome from anyone who runs bottle grade PET. Thanks.
