A Gravimetric Dosing unit is a specialised device used primarily in the plastics industry for the measurement and dispensation of materials based on their weight. Our systems operate on a ‘loss-in-weight’ technology, a mechanism that continuously monitors the storage and mass of a particular substance, dispensing it with an exceptional degree of accuracy.
The advantage of Gravimetric Dosers over other methods like Volumetric Dosing, which measure solely on volume, is its ability to offer superior control and precision.
Inaccurate material mixing can lead to inconsistent product quality and increased wastage. In preventing this, the Gravimetric Dosing Unit is crucial in environments where precise blending and exact proportions of materials are required.
Summit Plastics Automation provides a variety of dosing units, including Gravimetric and Volumetric Dosers, suitable for a variety of different applications.
The right system for you will depend on your unique needs. For help choosing, we recommend talking with our expert team. As a starting point, things to consider include:
Once your Gravimetric Doser is installed, we provide a variety of after-sales services, for peace of mind and to ensure your system is operating efficiently for years to come.
For older equipment, we offer refurbishment and repair services. Our committed service engineers strive to restore your equipment as quickly as possible and to the highest standards to reduce your downtime – either on-site or at our workshop in Tamworth. In addition, our engineers provide preventative maintenance visits to help optimise your machinery. These visits are intended to prolong the life of your equipment and minimise the risk of unforeseen failure.

Here at Summit Plastics Automation, we provide a range of dosers to meet all applications. For Gravimetric applications, we also provide the Gravimetric Feeder MGF by Maguire.
Beyond this, our offering also includes:
Gravimetric and Volumetric Systems differ in their methods of measurement and calibration. Gravimetric Units dose based on weight, using a load cell for measurement and a self-calibrating dosing system. This ensures control over product quality and cost savings in the long run, despite a higher initial investment.
Volumetric Units, on the other hand, supply material based on volume within a set timeframe. They require manual calibration and selection of dosing speed, making them more suitable for smaller production processes. They offer a lower immediate investment but have a less precise feeding process and limited control over product quality.
In many instances, a Gravimetric Doser is not necessarily faster than a Volumetric doser. The speed of dosing depends on your specific machine, materials, and processing conditions. However, these systems are often more accurate than their Volumetric counterparts, as they measure the actual weight of the material being dosed, eliminating variables like density or ambient conditions which can affect Volumetric measurements.
This precision may result in a slightly slower process, but the trade-off is the increased accuracy and consistency, which are critical in many industries. Therefore, while a Gravimetric Doser might not be faster, it could be more efficient in the long run.
