Claims (1)

Способ изготовления заготовок деталей путевой техники с использованием мембранобарической стабилизации задействуемых литейно-формовых фрагментов, включающий отбор требуемого полостеоблицовочного мембраноматериала, составление полостеформовочной композиции, компонование с ее использованием рабочей отливочной полости в мембранобарически стабилизированном формообъеме, формирование в скомпонованной полости несущего тела необходимой заготовки и изъятия сформированного тела из выработанной полости для преобразования его в регламентированные технологические пределы, отличающийся тем, что формирование полости несущего тела необходимой заготовки осуществляют при ведении принудительного электрозаземления его массы, и это электрозаземление инициируют отведением от массы электрических зарядов при микропотенциалах 0,1 - 5,0 В, причем отбор требуемого полостеоблицовочного мембраноматериала ведет из ряда пленочно-полимерных материалов, у которых образуемые жидкие и твердые конденсанты летучих и твердых продуктов пиролизола не нарушают резисторную изотропность составленной полосте формовочной композиции, в частности берут пленочно-полимерный материал этиленвинилацетатного происхождения.A method of manufacturing blanks of railway equipment parts using membrane-pressure stabilization of the casting molds involved, including selecting the required cavity-facing membrane material, composing a cavity-molding composition, composing with it a working casting cavity in a membrane-pressure-stabilized molding volume, forming the necessary body in the assembled cavity of the carrier body and removing it from the developed cavity for converting it into regulations centered technological limits, characterized in that the formation of the cavity of the supporting body of the necessary workpiece is carried out when conducting forced electrical grounding of its mass, and this electrical grounding is initiated by the removal of electric charges from the mass at micro potentials of 0.1 - 5.0 V, and the selection of the required cavity-facing membrane material leads from a number film-polymer materials in which the formed liquid and solid condensers of volatile and solid pyrolysol products do not violate the resistor isotropy of the ION cavity molding compositions, in particular taking film-polymeric material is ethylene vinyl acetate origin.
