FIELD: manufacture of building materials. SUBSTANCE: invention aims at improving quality of compacted bricks owing to imparting uniform density to crude bricks, increasing strength, decreasing size distribution, and eliminating breaking in brick structure. To that aim, method includes molding crude bricks in stationary press mold in two steps during one move of tool, in the first step within 60-70% of full move of compacting tool and 100% of two-side double application of full molding force. Stop of upper tool when press mold is closed is accomplished by stand of controllable effort. EFFECT: improved product quality. 2 cl, 12 dwg, 2 tbl
