EXTRUMATE

Product catalog summary

Product Overview: EXTRUMATE Yield Control is designed for mono and multi-layer extrusion lines, applicable to blown film, cast film, sheets, tubes, profiles, and cables. It ensures precise control of the weight per meter of the end product, maintaining tight tolerances despite variations in extruder throughput due to factors like filter clogging, melt temperature changes, polymer viscosity, and screw wear.

Key Benefits:

Reduces start-up and production change times.
Optimizes raw material consumption and minimizes waste.
Prevents out-of-tolerance production, ensuring consistent quality and repeatability.

Product Models and Capabilities: EXTRUMATE is available in models supporting throughputs from 150 to 2000 kg/h. It features easy installation with a weigh hopper that replaces the conventional feed hopper, and is prearranged for additional hopper or vacuum loader installation.

Setpoint Entry Options:

For multi-layer extrusion lines: Control extruder rate by weight, product weight per running length, or average thickness (requires film width and polymer density input).
For single-layer extrusion lines: Control total extrusion throughput rate by weight and percentage layer ratio, product weight per running length, or average total thickness (requires film width and polymer density input).

System Operation and Features: The system allows quick ingredient changes and thorough cleaning, with easy access to components. It uses a weigh hopper for continuous material weighing, turning the extruder into a gravimetric metering device. It can control extrusion throughput, line speed, or both, and maintains constant layer-to-layer percentage ratios in multi-layer lines.

FAST INGREDIENT CHANGE, QUICK AND THOROUGH CLEANING YIELD 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....
