BFS/BFH Metering Feeders
At the Throat Models
Conair feeders provide injection molders and extruders with a versatile, economical way to volumetrically meter colorants or other additives into the flow of virgin material directly at the throat of the processing machine.
By metering additives directly at the throat, greater savings in material inventory and colorant can be achieved over traditional pre-colored or centrally blended material schemes.
- Model for low/high throughput
- Injection or extrusion control
- Easy, no-tools cleanout
- Digital setpoint accuracy
- Optional low level alarm
