Feeders are auxiliary equipment that dispense a measured amount of an ingredient—a resin, a colorant, or an additive—into resin entering a processing machine. The term "volumetric" refers to one way that a feeder measures and dispenses an ingredient. The other way is called "gravimetric.". Let's briefly look at both.
