FIELD: castings. SUBSTANCE: rarefication is created on side of a model in applying it with synthetic film. Passages for flowing-off are made by inserting pipes in loose material (filler) at setting it on the model. Passages for flowing-off and stand are made of synthetic film of the shell welded hermetically and used for vacuum-film moulding. Compressed air is fed into the shells. When rarefication is created in the mould the shells of the passages for flowing-off is depressurized. Films of the shell made of welded hermetically synthetic film are secured to the model with holders-sucking disks. EFFECT: enhanced efficiency of working by hand. 2 cl, 3 dwg
