Frequently Asked Questions

A gravimetric blender controller manages and monitors the dosing process within a gravimetric blender, ensuring each material component is weighed accurately before blending. By controlling material ratios in real time, gravimetric blender controllers help improve product consistency, reduce material waste and maintain precise recipe control for injection moulding, extrusion and blow moulding applications.

Modern gravimetric blender controllers can typically achieve dosing accuracies of ±0.1% to ±0.5%, depending on the material and system configuration. High-accuracy controllers continuously measure material weight and automatically adjust dosing rates to maintain the correct blend ratio, helping manufacturers improve quality control and reduce costly overuse of additives, colourants and virgin materials.

Yes. Many advanced gravimetric blender controllers offer connectivity through Ethernet, OPC UA, Modbus or other industrial communication protocols. This allows manufacturers to integrate blending data with factory monitoring, MES and Industry 4.0 systems, providing real-time production visibility, recipe traceability, material consumption reporting and improved process control.
