Characterization of molding and casting materials

In sand and gravity die casting, the correct selection of molding and casting materials ultimately determines the properties and quality of the finished castings to a large extent. A detailed characterization of these materials is therefore of great importance. It also enables a better understanding of the relevant influencing variables between material use and casting process.

At the Fraunhofer IGCV we have access to high-quality testing methods:

Characterization of casting materials:

• Qualitative and quantitative microstructure characterization
• Reflected light microscopy with phase analysis, particle analysis, phase classification, phase counting
• Scanning electron microscopy (SEM) and X-ray microanalysis (EDX)
• Tensile and compression testing
• Micro- and macrohardness testing
  
  

Characterization of molding materials:

• Surface roughness measurement
• Particle image analysis
• Flexural strength
• Gas permeability test
