High-Performance, Cost-Effective Volumetric Feeder

Movacolor’s MDS Volumetric Feeder has been developed for plastic processors that require a high-performing dosing unit at a cost-effective price. The unit is said to offer reliable dosing with the capability to handle a wide variety of materials, from granular to microgranulate and free-flowing powder up to 70°C. It proves its value in easy operation, minimizing overdosing and as a result saving on material and process costs.

The feeder comes with an efficient and reliable stepper motor, a rigid dosing house, a stainless-steel hopper and a robust neckpiece. Optimal blend homogeneity is accomplished through inline dosing using a centralized insert within the neckpiece.

All the dosing tools from Movacolor’s MDS Balance product range will also be available for the MDS Volumetric Feeder, providing users with the flexibility to choose the most suitable dosing tool for their specific process. The stepper motor and selection of dosing tools offer an rpm range from 0.1 to 200 in 0.1 rpm increments, and the capacity to dose up to 72 kg (about 159 lbs/hr.

The feeder enables a swift 60-sec. cleaning and material change through a discharge valve and easy motor, hopper and dosing tool release. As a result, downtime and changeover time can be minimized.

The feeder comes with a newly developed 4.3-inch VoluTouch controller. This capacitive touchscreen controller can manage up to two units and is equipped with intuitive functionalities such as easy recipe management. A wireless web interface enables data and recipe transfer. The VoluTouch controller can seamlessly connect with an extruder's tacho signal, initiate the injection molding machine in timer mode and features a relay mode. This ensures smooth integration with any production line.

The MDS Volumetric Feeder is part of Movacolor's modular dosing concept and can be combined with other units and/or specifically tailored to fit the requirements of the user’s production process.
