Способ относится к порошковой металлургии, в частности к производству изделий из металлических порошков. Предлагаемый способ изготовления изделий включает загрузку в эластичную оболочку порошка, его уплотнение, герметизацию оболочки, ее гидростатическое прессование и спекание заготовки. Новым в способе является то, что осущестляют предварительное гидростатическое прессование эластичной оболочки с дополнительной досыпкой в нее порошка и с величиной давления, составляющей 16 - 22% величины давления основного гидростатического прессования. Изобретение позволяет повысить качество изделий, преимущественно толстостенных, и тем самым снизить брак изделий и увеличить выход годного.The method relates to powder metallurgy, in particular to the production of products from metal powders. The proposed method of manufacturing products includes loading into the elastic shell of the powder, its compaction, sealing the shell, its hydrostatic pressing and sintering the workpiece. A new method is that they carry out preliminary hydrostatic pressing of an elastic shell with an additional filling of powder into it and with a pressure of 16-22% of the pressure of the main hydrostatic pressing. The invention allows to improve the quality of products, mainly thick-walled, and thereby reduce the scrap products and increase the yield.
