Volumetric powder dosing solutions<\/span><\/b><\/h3>\n

Dosing powders in injection molding and extrusion presents significant challenges. Free-flowing powder is often difficult to dose consistently due to variations in composition, density, and flow properties, which can lead to waste and unstable production. A reliable volumetric powder dosing solution is essential for precision and efficiency.<\/span>\u00a0<\/span><\/p>\n

At Movacolor, we address these demands by integrating advanced hardware and software into our volumetric powder dosing systems. This enables plastics producers to save up to fifty percent on powder additives while ensuring stable, accurate dosing. Our systems minimize waste and streamline production, making volumetric powder dosing efficient and reliable, even with free-flowing powders.<\/span>\u00a0<\/span><\/p>\n

Powder dosing with a gravimetric or volumetric dosing feeder\u00a0<\/span><\/b><\/h3>\n

Free-flowing can be accurately dosed with either a gravimetric or volumetric Movacolor feeder. When deciding which type of feeder to use, consider whether you prefer a lower initial investment with a volumetric feeder or seek long-term savings and precision with a gravimetric feeder.<\/span>\u00a0<\/span><\/p>\n

Volumetric powder dosing is a straightforward approach where a set volume of material is dispensed based on predefined settings. Volumetric feeders typically require manual calibration, meaning they rely on the operator to adjust settings to match the desired output rate. The MDS Volumetric Feeder is an advanced option among volumetric feeders, featuring pre-calibration to enable dosing at specific percentage rates, reducing some manual intervention.<\/span>\u00a0<\/span><\/p>\n

Gravimetric powder dosing, on the other hand, is an advanced, highly accurate method that uses closed-loop control and loss-in-weight technology to continuously measure and adjust the dosing process. This type of feeder automatically calibrates itself, ensuring optimal precision and efficiency by maintaining a consistent dosing rate.Movacolor\u2019s gravimetric feeders offer significant long-term cost savings due to their accuracy, which minimizes material waste.<\/span><\/p>\n

Powder dosing system with a modular design<\/span><\/b>\u00a0<\/span><\/h3>\n

All dosing\u202fproducts\u202fof Movacolor are built on a modular design, allowing flexible combinations and adjustments to meet the specific requirements of injection molding or extrusion application. \u00a0This is interesting for plastic producers who use multiple powders or a mixture of powders, granulates and liquids at the same time. They can opt for a multi-component Movacolor dosing system. One multi-component dosing system can dose up to six different additives, allowing to optimize the recipe of the feed and eliminating pre-blending requirements.<\/span>\u00a0<\/span><\/p>\n<\/div><\/div><\/div><\/div><\/div><\/div><\/div><\/section>\n","protected":false},"excerpt":{"rendered":"Volumetric powder dosing solutions Dosing powders in injection molding and extrusion presents significant challenges.
