The MCS Continuous Loss-in-Weight Blender is Movacolor’s gravimetric solution for continuously blending multiple materials with high precision in extrusion processes. It is designed for applications where throughput can fluctuate significantly over short periods of time, and where maintaining a stable mixing ratio and consistent product quality is essential. This makes the system particularly suitable for demanding processes such as filament yarn production, where melt pump interruptions and thread breaks frequently cause output variations.
All materials, including the main material, are dosed continuously and simultaneously into an weighing hopper. Inside this hopper, the materials are constantly monitored for weight. Because the system always knows the total hopper capacity and material level, each dosing unit can quickly adjust its output to match changes in extruder demand and maintain the correct mixing ratio at all times.
The fully gravimetric loss-in-weight control enables the system to immediately detect changes in extruder output or differences between the dosing units and extruder demand. Each dosing unit automatically corrects its output, ensuring a stable hopper level and a consistent, high-quality blend — even when production conditions are unstable.
The MCS Continuous Loss-in-Weight Blender is available with 2 to 6 ingredients and supports throughputs up to 1500 kg/h. Thanks to its modular design, additional dosing stations can be added after installation. The system is suitable for granules, regrind and free-flowing powders. High-temperature versions and dosing-stop options are available, making the system flexible and future ready for demanding materials and evolving production needs.
