Plastic industires(PI Custom Molding) makes all kinds of great plastic stuff! Like polymer rifle stocks, pet safe doggy doors, swimming pool kits, chicken coops, plastic boxes… all kinds of crazy stuff all made out of plastic. It’s about 5 minutes off of interstate 75 and about 45 minutes south of Knoxville and 45 minutes north of Chattanooga… its right in between the two cities in Athens. If you need something a plastic injection product then I’d let these guys quote for sure.
