Extrusion International 5-2022

22 Extrusion International 5/2022 INDUSTRY NEWS NewChoices of Gravimetric Feeders  With over 30 years of experience in gravimetric blending and dosing technology, Maguire is pleased to introduce a new feeder line that can be configured in any optimal way to accommodate various processing requirements. The new feeder models allow for up to 4 different size auger feeders, all located on one mount- ing 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 bolding and extrusion control applications. Since 1980, Maguire feeders have helped processors save tens of thousands of dollars per year thru accurate dispensing of color and additives. The standard MGF line provides robust hardware, integrated with industry leading software, to provide consistent control and ac- curacy that is intelligent and easy to use. This standard Maguire Gravimetric Feeder (offered in 3 auger sizes: 3/8”, ½” and 1”) have historically included an analog or touchscreen control, along with different mounting frame options and high temp configurations. The series offer twin load cell technology with a dosing accuracy of ± 0.2%. These new available options allow processers much more flexibility and increased performance for all types of molding & extrusion processes. 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 (4) differ- ent size auger feeders on one mounting frame all using a common touch screen control. This allows the flexibil - ity to dispense multiple additives/materials within one frame and one controller. The center hopper dispens- es the virgin material. For each unique feeder the dis- pensed 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 (4) 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 com- ponent, 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 pack - age, 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 ap - plications 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 per hour and/or weight per length. 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 utiliz- es a simple (digital push button) setpoint control and a stepper motor to provide consistent letdown ratio with- out any use of load cells. Conversion kits are available for upgrade to full gravimetric capability. All Maguire Gravimetric and Volumetric Feeders are backed by an industry leading 5-year Warranty.
