The porous structure of polymer and gypsum molds is analyzed. Models of their structure are proposed on the basis of the model of chaotically located spheres and the theory of percolation. The calculation expressions for evaluating the parameters of the porous structure are refined and the obtained structural parameters of the polymer and gypsum molds are given. Calculation results are presented.
