Static Mixers Extrusion

Melt homogeneity pays off!

Insufficient surface quality, long cooling times, uneven thickness tolerances or other quality problems often limit maximum production output. Promix melt blenders eliminate these limitations sustainably and lead to significant cost savings.

Melt blenders for extrusion – melt homogeneity pays off!

Would you like to optimize your extrusion process? Improved melt homogeneity and a more uniform melt temperature create tighter thickness tolerances and better surface quality. And quite often, it can also increase production throughput. Promix offers you highly effective static mixers and melt blenders at low
investment costs.

They are supplied ready for installation, including heater bands and holes for pressure and temperature sensors. The melt blenders are usually installed downstream of the screen changer & gear pump, and upstream of the die. The very short installation length allows easy retrofitting in existing extrusion lines.

Installation principle: the melt blender is installed downstream of the extruder and the melt pump upstream of the die

Minimal maintenance and quick product changeover

The Promix melt blenders are characterized by a unique self-cleaning behavior. Thanks to the optimized mixer structure, the melt flows very evenly through the mixer and does not form any dead zones. As a result, Promix melt blenders are maintenance-free in most cases. The very short product or color change times also avoid unnecessary production waste.
