powder metallurgy, namely press-molds for pressing articles such as sleeves of powder materials. SUBSTANCE: press-mold includes holder, elastic die, elastic separating sleeve and elastic insert, upper punch, lower punch and base. Upper punch is builtup one; it has outer and inner cylindrical lids mounted with possibility of axial motion one relative to another. In cavity of inner lid there are elastic compensating member and cylinder that may perform axial motion. Outer lid is provided with fixing member. Invention allows to make thin-wall dead-bottom round and non-round articles of different powder materials in condition of automated production process. EFFECT: enhanced quality of products. 1 dwg
