Injection Molding of a Plastic Tray for a Sporting Goods Application

A client in the sporting goods industry approached CNR Group, LLC to mold a large number of trays to be used by sportsmen who reload their own ammunition. These trays are designed to hold the priming charge throughout a reloading process. The 3.9" long, 3.720" wide, and 1.87" high pieces were molded with a Sumitomo SE100DUZ, 110-ton fully electric injection molding machine. Each of the trays weighed 46.5 grams and we were able to hold tightest tolerances of ±.005" throughout the entire molding process.
