Conair MedLine® TF1

Gravimetric Feeding; Calibrated to Medical ISO Standards

Optimize your feeding process with the Conair MedLine TrueFeed gravimetric feeder. Units are simple to install and use, extremely accurate and economical. These color and additive feeders deliver accurate feeding rates on the basis of continuous loss-in-weight metering technology with closed-loop control of the feeding speed. This MedLine version of Conair’s popular TF Feeders is calibrated to ISO standards and features RAL 9003 paint.

The MedLine TrueFeed can be used in injection molding, extrusion and blow molding processes. All models operate with the same bi-lingual, user-friendly touch screen control.

Reduce your material costs

The consistency of this feeder ensures that every pellet counts. Absolutely no material waste. Unique dispensing cylinder eliminates pulsing outputs of auger and pocket type feeders.

Increased productivity

The TrueFeed™ does not require time-consuming color calibration when materials are changed. Eliminates machine downtime associated with conventional volumetric feeders.

Unbeatable accuracy

The dispensing cylinder is driven by a stepper motor for consistent speed. The design ensures that the colorant is dispensed evenly, extremely accurately, and without any pulsation from the cylinder into the plastic, giving you maximum control of the process and the end product.


No tools required for material and color changes.
The unit is easy to disassemble. Simply release the knob holding the deeder to the scale, remove the feeder, pull back on the slide gate to drain the material from the hopper, then release the motor clamps and remove the motor and dispense cylinder.
