Whether you’re producing complex automotive components, precise medical devices, or everyday consumer goods, the consistency and quality of your materials directly impact the final product. One of the most crucial elements in this process is dosing accuracy.
At Movacolor, we understand that achieving the highest-quality output requires dosing solutions that deliver precision, consistency, and reliability. Our expertise in gravimetric dosing with balance technology sets us apart.
The Power of Gravimetric Dosing
Gravimetric dosing systems are the highest standard for accuracy in the plastics industry. Unlike volumetric systems that dispense material based on volume, gravimetric systems measure the actual weight of the dosed material. This method ensures that the exact amount of material is delivered every time, regardless of variations in bulk density.
Understanding Loss-in-Weight Systems
At the heart of our gravimetric technology is the loss-in-weight principle. In a loss-in-weight system, the dosing unit continuously measures the decrease in weight of the material hopper as the volume goes down. By monitoring this weight loss in real time, the system calculates the actual mass flow rate of the material. This feedback allows for automatic adjustments to the dosing speed.
The loss-in-weight method provides unparalleled dosing accuracy based on the actual weight of the material delivered, not just an estimated volume. This precision is crucial when working with expensive colourants or additives, where minor deviations can lead to significant cost increases or product inconsistencies.
Balance Technology in Dosing
The essence of Balance Technology lies in its adaptive nature to fluctuations in material weight. The load cell, continuously gauging material weight in the hopper, dynamically adjusts the feeding rate to maintain alignment with the set point. This real-time adjustment is key to achieving dosing precision of up to 0.05%, resulting in a finely tuned dosing process that optimizes material dispersion while minimizing waste and enhancing overall production efficiency.
Why Dosing Accuracy Matters
Accurate dosing is integral to achieving the highest product consistency and quality levels. Manufacturers ensure that every part meets stringent specifications by precisely controlling the amount of additive used.
- Consistency: Dosing accuracy guarantees uniform colour and material composition across all products, reducing the likelihood of rejects and rework.
- Cost-efficiency: Using the exact amount of material required minimizes the overuse of expensive additives or colourants, saving significant production costs over time.
- Quality Assurance: Precise dosing maintains the integrity of the product, which is essential for applications with strict regulatory standards, such as medical devices or food packaging.
- Reduced Downtime: With accurate dosing systems, there’s less need for recalibration and fewer production interruptions due to incorrect material feed.
The Movacolor Advantage
Movacolor’s dosing systems are designed to address the challenges faced by plastics manufacturers—our gravimetric solutions include the MDS Balance, MCS Regrind, and MCS Off-line dosing.
- MDS Balance: Equipped with advanced dosing software and a centred load cell, the MDS Balance can accurately measure the ‘loss-in-weight’ of the material in the hopper, regardless of possible deviations caused by vibrations of the production machine. Our Balance technology software automatically adjusts the feeding rate to stay as close as possible to the set point, resulting in dosing accuracy of up to 0.05%.
- MCS Regrind: The MCS Regrind is an advanced closed-loop dosing system that simultaneously doses regrind material—such as rejects and sprues—and additives like colourants into the production process. Using Movacolor’s gravimetric dosing technology, it features a dual-unit configuration where one unit doses regrind and the other doses additives. This setup ensures continuous loss-in-weight measurement and automatic adjustment of dosing rates, optimizing material usage while maintaining consistent product quality.
- MCS Off-line dosing: The MCS Off-line dosing system is an innovative floor-level dosing solution that achieves high dosing accuracy and blend homogeneity independent of machine vibrations. In addition, access to the dosing equipment is not hampered by hazardous climbing on ladders or stairs.
