FIELD: process engineering.
SUBSTANCE: invention relates to production electrical carbon articles. Compaction of articles composed of electrical machine brushes and current collector inserts comprises mixing of graphite filler with binder and their filling inside the die. Said mix is compacted by horizontal male die at female die top open and, then, compacted by vertical male die. Powder mix is compacted at horizontal male die displacement rate of (0.2-0.0004 m) mm/s where m is powder mix bulk, g.
EFFECT: higher density and electrical conductivity of the obtained products.
