Spirit level

Cost-effective, traceable production of complex parts

The example of the spirit level shows how 100 percent traceability and cost-efficient production can be achieved. Thanks to the ARBURG Turnkey Control Module (ATCM) SCADA system fitted in the turnkey system, all the relevant process and quality data for each individual component can be traced at any time.

In the system, the two halves of the injection-moulded housing are assembled with three bubble tubes after demoulding to form the ready-to-use part. Each part is marked with a QR code following an optical quality inspection. The data can then be retrieved at any time on a part-specific website. In practice, this forms the basis for big data analyses and 100 percent traceability.


  • "Ready-to-use" complex parts: fully automated production, assembly and testing
  • Digital transformation: important data can be retrieved and analysed any time on a part-specific basis
  • Plant-specific SCADA system: relevant process and quality data can be saved and merged
  • Efficient automation: handling of parts with MULTILIFT V featuring additional A axis


Basic specifications

Spirit level
Cavities: 1+1
Part weight: 35.7 g
Material: ABS
Cycle time: 50 s


The centrepiece of the system is an electric ALLROUNDER 470 A with OPC UA interface. The 1+1 cavity family mould is used to produce two housing parts (lower shell and cover) in a cycle time of about 50 seconds.

Robotic system
A MULTILIFT V 15 linear robotic system removes the housing sections. An additional A-axis is used to set down the cover and lower shell directly into an assembly station without requiring an additional turning station and three bubble tubes are inserted to produce the ready-to-use spirit level.

ARBURG Turnkey Control Module (ATCM)
The ATCM stores data from the injection moulding process for each component and combines this with the results of the camera-based functional test. If required, the ATCM can start non-cyclical production processes, for example the removal of parts for quality control purposes.
to digital transformation


The top priority is the common goal of always finding the most cost-effective solution. This calls for interdisciplinary expertise. As a technology and systems partner we cover a particularly broad spectrum and can offer you expert support for the implementation of your requirements.

Technical injection moulding
For large unit volumes it is worthwhile to integrate sequences into the production process through automation in order to produce ready-to-use articles in a single step. The spirit level example shows how a turnkey system makes it possible to meet a zero-fault production target individually and with traceability at all times.
