Paper present results of moulds properties as follow: permeability and shell Module of Rupture (MOR). Measurement and tests have been made on moulds from two different mould systems: water and alcohol. Mechanical properties measurement was made on standard samples. Permeability measurements required preparing special shape samples [4]. All scope of tests have been realized in WSK ”PZL-Rzeszów” S.A. Results showing permeability and mechanical properties of two mould systems in function of quantity layers.
