Test Lab for Moulding Materials

A special role is attributed to the ÖGI in the field of moulding materials. Numerous publications, scientific papers, lecture activities and close cooperation with project partners and the foundry industry are examples of the importance and high status of the moulding materials department. Not only forward-looking new developments, but also traditional sand systems are examined and tested using the latest technology. The high accuracy and precise digital recording of our measuring equipment create new possibilities for data evaluation and quality assurance of moulding materials.

The moulding sand is on its way from an auxiliary to a material.

Test Spektrum

Quality assessment of basic mould materials and mould materials mixtures

Continuous process monitoring of batch mixes from customers (e. g. weekly parameter assessment)

Support and monitoring of process optimisation 

Applications

Possibilities for the production and testing of sample series from wet-cast sands and cores (cold-box and hot-box).
Testing options:

  • Screen analysis
  • Annealing loss
  • Residual moisture
  • Core breakdown
