FIELD: foundry.
SUBSTANCE: method comprises steps of providing fluidized state of filler; spraying binder into upper layers of fluidized filer for cladding grains of filler with thin films of binder. Invention provides lowered consumption of binder by 25 - 30% and predetermined strength of sand.
EFFECT: target value of molding sand strength at lowered consumption of binder.
