Abstract

In this work using of self-hardening mixtures to manufacture castings is studied. The information about appliance of different sand mixtures in the world foundry industry is given. Different kinds of resins, advantages and disadvantages of mixtures made with these resins are discussed. Affecting on friability factors are studied. Casting defects caused by increased friability of the mold are analyzed. Optimal values of friability necessary to obtain qualitative forms are given.
