FIELD: plastic metal working, possibly forming-drawing parts of high-melting materials such as molybdenum and its alloys. SUBSTANCE: disc blanks are lubricated and hot formed in die set with gap between punch and die provided while taking into account material thickness and allowance for thickened portion of material extension. At first blanks are sorted to groups with minus and plus allowance values. Then value of thickened portion for material extension is experimentally determined for each group. Two die sets with different gap values are used. Blanks with plus allowance are formed in die set with larger gap and blanks with minus gap are formed in die set with smaller gap. EFFECT: significantly lowered number of rejects caused by metal fractures, stratification. 2 dwg
