Abstract
It is known that most casting molds are made using a binder. To exhibit its effect, the binder additive must initially be in the liquid state, then form a film on the surface of the solid phase, develop a cuff around the contact points between the grains, and solidify, thereby turning the bulk mixture into a monolithic medium. Sand-resin mixtures meet all these requirements. Casting molds made from such mixtures enable the production of high-quality castings from a wide range of alloys. However, their widespread industrial application is hindered by the relatively high cost of the binder, pulverbakelite. Therefore, research aimed at improving the manufacturing processes of durable sand-resin molds while reducing the content in the mixture, without compromising other parameters, is highly relevant.
