VT800ST - Digital Station 4.0
For the production of "density index" samples
With acquisition of the sample creation parameters


The device has been developed specifically for the requirements of Foundry 4.0. The IDECO VAC-Test & Density Index device is a system for simple determination of the pore potential of liquid aluminium alloys. In order to determine the actual pore potential, a sample is taken from the melt to be tested using a sampling ladle. After casting in two special sample crucibles, one sample solidifies at atmospheric pressure and one at 80 mbar absolute pressure.

Once the samples have cooled down, the density index is determined on the Density Index Analysis System according to Archimedes' principle. The density index represents the percentage density difference of the two samples created.

Thanks to the integrated microprocessor control, the sample creation particulars (e.g. date / time / duration / vacuum / casting line / furnace, etc.) can be recorded and exported together with a sample identification for other systems. The sampling process becomes transparent, traceable and can be digitally further evaluated as defined by Foundry 4.0.

  • Quick and easy determination of the melt quality by the caster
  • The sample crucibles are reusable.
  • Fan cooling of the sample crucibles to room temperature guarantees consistent testing success
  • Infinitely variable working vacuum for precise vacuum setting.
  • The vacuum technology is calibrated by IDECO as standard with a certificate and seal.
  • Stationary device.
  • Integrated vacuum monitoring
  • The device is network-compatible as standard and therefore offers every possibility for individual integration into the in-house QA system and for further processing of the captured sample creation parameters (e.g. in conjunction with a Density Index Analysis device with PC system).
