Extrumate – Gravimetric hopper and extrusion control

Suitable for mono and multi-layer extrusion lines, for blown film, cast film, sheets, and for the production of tubes, profiles and cables. Controls the weight per meter of end product reaching and maintaining tighter tolerances, regardless of changes in extruder throughput commonly caused by:

progressive clogging of the filter
variations in melt temperature
variations in polymer viscosity or bulk density
plasticizing screw wear.

Reduces start-up and production change.
Optimizes consumption of raw materials and cuts down on waste.
Prevents out-of-tolerance production.
Ensures constant quality and repeatability.

MORE INFORMATION

EXTRUMATE is available in various models to meet mono and co-extrusion process requirements. Throughputs of 150, 300, 600, 1000 up to 2000 kg/h.

Easy installation of the weigh hopper directly on the extruder throat replacing the conventional feed hopper.

Self-supporting structure suitable for pre-storage hopper and/or vacuum loader installation without additional supports.

The on-board control box does not require any floor space.

All parts that come into contact with the ingredients are made of satin stainless steel, or of food-grade materials or finishes.

Practical and easy access to all components.

Feed hoppers with sight glass for visual level control and quick-release ring clamp for easycover removal.

Reduced installation costs. Complete wiring of the dosing unit is carried out by the manufacturer.
Dedicated standard weights kit for load cells calibration.

Easy installation of the weigh hopper directly on the extruder throat replacing the conventional feed hopper.

Integrated loading system control (SmartConvey)

Fully automated loading system control, easy operated by the same interface used for gravimetric blenders. One or more vacuum pumps to serve more than one receivers whose association can be set through configuration. All receivers linked to the same pump are served in turn, according to a priority sequence automatically assigned. Loading active control to reduce ingredient at minimum on changeover
