AF Series
AF Series Volumetric Additive Feeders
AF Series Volumetric Additive Feeders have set the industry standard for accuracy and dependability in precision metering of color concentrate, regrind, and other additives. Proven mechanical features include modular design for one or two materials, low-profile throat section, and an easy-to-clean, interchangeable stainless steel auger assembly.
With a constant flow of primary materials flowing into a machine feed throat, the AF Series feeder meters a free-flowing additive directly into the center of this flow in a consistent and uniform pattern, resulting in the ideal blend of materials. The AF Series Feeders can be used in virtually any injection or extrusion process. The AF-1 and AF-200 can also be used to starve feed an extruder. All of this makes the AF Series Feeder a superb value for your money.
REQUEST A QUOTE Find a rep- The AF Series is designed for injection molding and extrusion applications that require accurate metering of color concentrates, regrind, and other free-flowing additives. Select models can also be used to starve-feeding extruders.
- The AF Series meter additives directly into the center of the primary material flow in a consistent and uniform pattern. This helps achieve accurate additive distribution and blend consistency throughout the process.
- The AF Series combines proven volumetric feeding technology with a modular design, low-profile throat section, interchangeable stainless steel augers, and easy-clean components. This design provides flexibility, reliability, and simplified maintenance.
- Yes. An optional extruder tracking control is available, allowing the feeder to adjust output based on extruder speed for improved additive consistency during extrusion processes.
- Yes. Multiple options are available, including larger additive hoppers, injection calibration timers, extruder tracking controls, regrind auger inserts, alternate voltages, and specialized mounting configurations to support a variety of processing requirements.
- Additive feeders help meter color concentrates at controlled rates into the primary material stream, supporting consistent color distribution and reducing variation between production runs.
