Requirement:
Enhancing Production Data
In today’s industrial context, companies aim to leverage data to improve efficiency, prevent failures, and reduce energy consumption.
Requirement:
Control of the extrusion process
Synchronous and centralised regulation of critical parameters (speed and synchronisation with the other motors of the screw line, temperatures, melt pressure) to guarantee process stability, the rheological quality of the product and operational efficiency.
Solution:
Requirement:
Temperature control
Thermal stability of the molten polymer in every heating zone to ensure constant viscosity, dimensional consistency and surface quality.
Requirement:
Melt temperature measurement
Accurate monitoring of the temperature of the molten polymer before forming to ensure correct viscosity and process stability.
Solution:
Requirement:
Flow control through the melt pump
Adjustment of the flow rate of the molten polymer downstream of the extruder to obtain dimensional consistency of the product and constant quality.
Solution:
Requirement:
Dirty filter detection
Upstream/downstream pressure monitoring of the extruder filter to control the pressure on the device, in order to define manual or automated cleaning interventions.
