With the GJ1 Gas Permeability Tester, you can reliably determine the gas permeability of green sand test specimens in accordance with VDG guidelines. Gas permeability is a key parameter in molding sand testing, as it indicates how effectively gases can escape from the mold during the casting process. This helps ensure stable molding conditions and supports consistent casting quality.
