Flexible Feeder Line Suited for All Processes
New feeder models are said to offer the ultimate in flexibility for injection molding, extrusion, blow molding and extrusion control applications.
Maguire Products has introduced a feeder line that can be configured in any optimal way to accommodate various processing requirements. The new feeder models allow for up to four different size auger feeders, all located on one mounting frame, using a single common touch screen control. In addition, the company is introducing a volumetric feeder (MVF) option. These new feeder models provide ultimate flexibility for injection molding, extrusion, blow molding and extrusion control applications.
The new line gives processors much more flexibility and increased performance. These options can all be retrofittable in the field with current Maguire feeder equipment.
The new Maguire MGF+ line incorporates the standard gravimetric feeder options and includes up to four different size auger feeders on one mounting frame all using a common touch screen control. This allows the flexibility to dispense multiple additives/materials within one frame and one controller. The center hopper dispenses the virgin material. For each unique feeder the dispensed material is measured precisely and accurately to maintain the correct desired percentage – all controlled by one touch screen controller.
The new Maguire MGF+ 100L incorporates up to four different size auger feeders, and includes a virgin hopper that is on a pair of load cells so that the material within this hopper is also being weighed and controlled (by the same controller). All materials are 100% weighed and the additive components are ratioed to the primary component, regardless of changing throughput. This option is ideally used for extrusion applications.

The Maguire MGF+ 100X takes the process control one step further by including an extrusion control package, where the extruder drive control is managed with the same touch screen controller as the hopper and the feeders. This model used exclusively for extrusion applications streamlines the entire process and includes the center loss-in-weight (LIW) hopper along with up to four auger feeders. The LIW controller monitors the actual throughput of the line. The target throughput is set on the controller and when the operator switches to automatic mode, the controller will adjust the extruder drive to maintain target weight/hr and/or weight/length.
The MGF+ 100B is ideally used in injection molding applications. This model has no center hopper so that all materials must run through the feeders. This model includes a material collection bin with a level sensor that maintains material level by activating the dispense of the materials on demand.
Processors can also now choose from Maguire’s latest, most economical version of their volumetric feeder, the MVF. The MVF is designed for simple volumetric dosing of color concentrate and/or additive material. It utilizes a simple (digital push button) setpoint control and a stepper motor to provide consistent letdown ratio without any use of load cells. Conversion kits are available for upgrade to full gravimetric capability.
All Maguire feeders are backed by a 5-yr warranty.
