FIELD: technological processes.
SUBSTANCE: invention relates to foundry. Model equipment is assembled. Models are installed on a submodel slab. On the surface of the cast model, on which, during molding or pouring, the synthetic film is subjected to destructive effects, the reinforcing elements are fixed to adhere to the synthetic film to form a single reinforced structure. Synthetic film is put on the model rig with subsequent heating. For the fitting of the model equipment it is vacuumed with a synthetic film. Non-stick coating is applied to the synthetic film. Molding is placed on the molded plate. Mold is filled with loose filler and compact with subsequent removal of the mold. Second mold is made. Half molds are connected and filled with metal.
EFFECT: improved casting quality is provided.
