FIELD: process engineering.
SUBSTANCE: invention relates to casting. Proposed method comprises forming spherical perform with through bore that corresponds to plug bore and forming axles. Casting has ball shape that smoothly goes into truncated cone with its top base making the base of discard head. In casting, through bore lengthwise axis is arranged in horizontal plane of mould along mould break, While plug axles are arranged along vertical axis inside casing sphere. Tolerance for machining of spherical surface is set increased towards discard head located at casing top part.
EFFECT: higher quality of performs.
