Plastic Injection Mold Classification

When deciding what tooling source to use for your plastic injection molding project it is very important to figure out the mold class you are being quoted.  Mold classes offer a variety of different advantages. Some of the variables that can change with different mold classifications are: pricing, mold life, cycle times, and lead times. The chart below helps illustrate different characteristics of each mold class. If you have any questions give us a call today!
