Additive Feeder

Hamilton’s Additive Feeders precisely add colorants/additives directly into injection, blowmolding machines and extruders. Hamilton’s self-contained, highly versatile metering system is perfect for precise introduction of free-flowing plastics colorants or additives to base resins as they flow into your processing machine throat. Designed to eliminate off-machine tumble mixing, spillage, waste and premixed inventories and provide an economical, reliable method to custom blend materials just before they are processed. Choose between a variable-speed D.C. or A.C. motor to power a selected metering auger that volumetrically feeds colorants or additives upon a signal from either the injection or blow molding machine cycle, or in conjunction with extruder speed.
