Attention Molders!
How do you know you're getting the best prices from your regrind or excess inventory? Why not place a listing for them in The Plastics Marketplace™? It allows you to quickly and easily list the resin items you want to sell at your asking price. An injection molder recently sold 60,000 pounds of ABS regrind within days. Best of all, it doesn't cost you anything to list your materials. Please contact Mike Kmetz directly to list your materials today!
Also, if you are looking for any materials, let us know and we'll get the word out to our network.
