Maguire MGF Gravimetric Feeders
Maguire Gravimetric Feeders (MGF) offer precision dosing solutions that drastically reduce raw material waste and operational costs, making them an essential tool for manufacturers, especially when raw materials account for up to 70% of annual production expenses.
By automating material handling and eliminating manual mixing, MGF feeders ensure accuracy and efficiency with dosing rates up to 18 kg/hr for injection and 55 kg/hr for extrusion.
Selecting the right feeder can lead to substantial long-term savings and enhanced production flexibility, helping businesses maximise cost control and future-proof their operations.
Return on Investment
- MGF software and hardware significantly reduce wastage of colourants and additives.
- Maguire Gravimetric Feeders eliminate manual handling and mixing, lowering operational costs.
- Typically save 30% on masterbatch costs compared to manual or volumetric dosing.
Twin Load Cells
- A lightweight aluminium hopper mounted on two load cells measures the weight of the hopper and material only.
- It continuously monitors the loss-in-weight as material is dosed, automatically adjusting the flow rate.
- By only weighing the hopper and masterbatch, finer resolution load cells can be used, as opposed to weighing the entire feeder assembly and motor. This ensures maximum precision and control.
Accuracy of ±0.2%
- The system automatically and continuously updates flow rate calibration throughout the production process.
- A stepper motor provides high-resolution control to dose masterbatch with an accuracy of ±0.2%.
- The combination of dosing screws and software control offers industry-leading precision.
PRIME Calibration
- Fast-track calibration at startup, fully automatic and ready within seconds.
- The system primes the screw and barrel with material, preparing it for immediate production.
- This results in faster startups and reduced scrap rates.
100% Injection Colouring
- Ideal for critical additives, masterbatches, and tints.
All material in the injection moulding machine barrel is now coloured, eliminating gaps and waste. - Perfect for fast cycling and small shot weight applications.
