Control and drive system upgrades

Modern production machines only can fulfil the high expectations of customers, if they can be operated and controlled in an easy and efficient way. With the MEAF control system, with its user-friendly features and many diagnostic tools, we can make life easier for operators and maintenance personnel on existing extrusion lines.

MEAF'S in-house developped control system ExtruSol is operated by means of a touch screen and can be set for different levels of access. The combination of the control system with the SpeedAdjust handwheels gives the operator the possibility to quickly, simultaneously and accurately change of the speeds main extruder screw motor, gear pump motor, polishing cooling roller motors and the co-extruder screw motor.

Advantages of implementing a control system upgrade:

  • Additional communication ports such as Ethernet and USB can be used;
  • Long term availability of spare parts is ensured;
  • The new PLC can be used for remote assistance and Industry 4.0 solution



Besides implementing a more user friendlier operating system, there is the possibility of retrofitting outdated analogue DC-drives with new digital AC-frequency drives. This might be required if existing units can no longer be repaired, are time-consuming or spare parts are no longer available due to discontinuation by the supplier.

Advantages are:

  • Increased energy savings
  • Reduced wear on machinery
  • Improved PF (Power Factor)

As processes are becoming more and more complex, the requirement for accurate data-analysis is becoming a vital part in the production sequence. With the integration of the ExtruSol control system, the possibility of storage of process data on a compact flash card or USB stick at a variable time interval (i.e. 10 seconds) is possible. This includes all extruder parameters (output, speed, temperature, pressure, etc.). The logged file can be used as a diagnostic tool in order to filter out material discrepancies or extruder performance.


When it is paramount after data review or during the extrusion process that an error has occurred, the remote assistance possibilities, which come with the control system upgrade, allow MEAF’s service engineer to review the errors and provide analysis from MEAF’s factory. This saves time-consuming visits to analyze the error


When the control/drive system upgrade has been done it:
  • will ensure long term availability of spare parts due to the standardization of the new system;
  • improves process controls;
  • makes the machine ready for remote assistance and Industry 4.0
