FIELD: investment casting with crystallization under pressure. SUBSTANCE: apparatus includes metal receiver and container with shell mold. Metal receiver includes base 1 with heat insulation layer 3 and changeable nozzle whose lateral wall are lined and whose bottom is made of liquid glass mixture. Container is connectable one, it has body 6 and cover 7 with mouth 8. Parting of container passes along base of mouth 8. Usage of mouth 8 allows to provide predetermined geometry size of cavity of metal receiver. Heat insulation layer 3 provides higher temperature of metal before filling mold 11, favorable condition for feeding castings and reduced remainder of billet. EFFECT: improved design. 3 cl, 1 dwg,
