Digital features of profile extrusion

ECO+ vacuum management

State-of-the-art vacuum management with control valves. Required vacuum volume can be provided by one (preferably, highest energy efficiency) or several FU-controlled vacuum pumps. The vacuum levels are set via control valves that draw the vacuum from a large vacuum reservoir – this means that there are no mutual influences.

Your advantage

  • Reduction in the number of vacuum pumps
  • Reduction of energy input into the cooling water
  • Reduction of power consumption through frequency control
  • Reduction of the reject rate by stabilising the professional quality and the production process

Annual savings potential*

€ 15.000 - 20.000.-

* Calculation basis: 1 line with 2 conventional vacuum pumps and 1 separation tank system

  • ECO energy efficieny

ECO vacuum FU-regulated

Vacuum supply in the dry area with frequency-controlled vacuum pumps, in the wet area with separating tank incl. Side channel compressor and water pump.

Cross Box

Vacuum management with one vacuum & water pump incl. Valve technology for extracting the calibrators and the vacuum/water tank

  • Crossbox

e:MAC – extrunet Multiple Air Control

Modern air management to influence profile sections. Matched to the profile geometry, reproducible

e:MAC-C: Air control on dry calibre with contour plate.

e:MAC-D: Air control in the die Influencing the melt flow by local cooling or heating

The air control unit can be a stand-alone unit or built into the calibration table.

Profile-related data recording in the central control.

Can be retrofitted to existing tools!

Your advantage

  • Longer production times due to less deposits
  • Reduction of the profile weight through extrusion in the lower tolerance range

Annual savings potential*

€ 25 - 30.000.-

*Calculation basis: 1 line with output 250kg/h and 1.5% weight reduction

e:MCC – extrunet Multiple Cooling Control

State-of-the-art cooling water management – digital control of the cooling water flows in the cooling calibres – influencing the profile geometry through local additional or reduced cooling.

Cooling problems can be recognised by the flow rate before any impairment occurs on the profile!

Different cooling water temperature levels for special cooling, cooling in dry calibres and cooling in the tool tanks can be realised. As a result, enormous savings can be achieved in cooling water circulation.

Cooling regime can be saved for each tool and is therefore reproducible. Early warnings in the event of malfunctions (cooling problems).

Your advantage

  • Reduction of machine downtimes
  • Reduction of capacity shortfalls
  • Reduction of the reject rate through stabilisation of the professional quality and production process
  • Reduction of cooling water consumption

Annual savings potential*

€ 20.000 - 25.000.-

*Calculation basis: 1 line with output 250kg/h and 0.5% scrap reduction

e:ASI – extrunet Air support internal profile chamber

Digitally adjustable air volume as supporting air for the interior of complex profiles (narrow hollow chambers, sealing profiles with hollow chambers).

e:PBD – extrunet Profile Breakage Detection

Early warning of profile breaks and partial profile breaks – optical, acoustic and digital – already within the dry calibration.

The automatic raising of the calibration table (increases the distance between the die and the calibration table) leads to relaxation and prevents material build-up between the die and the calibre.

Your benefit:

  • Reduction of machine downtimes
  • Reduction of capacity shortfalls

Annual savings potential*

up to € 10.000.-

Calculation basis: 1 line with output 250kg/h and 0.5 machine downtimes per week

e:PSC – extrunet Profile Slipage Control

Digital equipment to detect slippage on the profile with the initiation of countermeasures.

Only in conjunction with an external length measurement (measuring wheel).

Differential measurement between the encoder of the fume cupboard and the measuring wheel indicate slippage of the profile. The regulation influences the back pressure.

Your advantage

  • Reduction of machine downtimes
  • Reduction of capacity shortfalls

Annual savings potential*

up to € 10.000.-

*Calculation basis: 1 line with an output of 250 kg/h and 0.5 machine downtimes per week.

e:PWD – extrunet Profile Weight Detection

Digital recording of the actual profile weight on the tilting table.

Left/right discharge of the profiles (separation production/reject)

e:PMC – extrunet Profile Measurement Control

In conjunction with in-line profile measurement, the functions of e:MAC and e:MCC can be used to keep dimensions permanently within specified limits.

e:TPS – extrunet Table Positioning System

All axles motor driven

Measuring system on all axes

Profile-related data storage

Exact reproducibility

e:DIGI – extrunet data acquisition and data evaluation

extrunet systems are equipped with the digital data acquisition function.
The OPC-UA server integrated in the PLC makes the process data of the entire plant available.
The data transfer software “DATAFEED” retrieves this process data and transfers it to an SQL database.
All data are thus historically available and can be evaluated.

Scope of services:

  • Data acquisition of all relevant process data of the plant
  • Transfer of the data into an SQL database
  • 1x standard dashboard for the display of current production data via Grafana
  • 2x Standard reports
  • 2x e-mail notification
  • DATAFEED licence included

Licence SQL database not included
