FIELD: manufacture of pressed articles from multiphase materials such as all-wood, fibrous and powder materials of various nature, etc. SUBSTANCE: method includes action of quasistatic force of pressing on material placed into mold. In so doing, ultrasonic vibration is excited in material by action on material with wideband acoustic signal. Excited in material is multidimensional field of ultrasonic vibrations. EFFECT: high degree of compaction and equicompactness of molded material including manufacture of articles whose linear dimensions in longitudinal and transverse sections strongly differing from each other. 1 cl, 4 dwg, 3 ex
