MCPowder – high precision gravimetric dosing system for non-free-flowing powders

Dosing powders is one of the most difficult challenges in the field of dosing. Especially when we talk about non-free-flowing powders at extreme low rates. Expensive powder additives with high impact to your process require the best in the field of accuracy and reliability.

Movacolor has, based on its proven gravimetric technology, developed a compact powder dosing unit to do just that. The unit can dose as low as 100 grams per hour, but at the same time up to 40 kg/hr. Double spiral or auger and hopper agitation ensures a trouble free dosing of the most difficult powders. And this in injection molding and extrusion application.

The unit operates as a single unit, but can also be integrated in our unique modular continuous blending system, allowing to add the most difficult powders to the blend of your extruder. A special hopper loader frame allows a wide variety of hopper loaders or screw conveyors to be installed. Operation of the loaders is integrated in our 8″ full color touch screen control.

A truly unique product in the market which will make you forget any dosing problems you might have with powders right now.
