FIELD: wood-working industry; applicable in deformation of semifinished products of wood-fiber boards for manufacture of shaped products. SUBSTANCE: method includes heating of semifinished product to softening temperature to make it plastically deformable. Subject to heating is, at least, one of upper semimold and lower semimold, and semifinished product is pressed in cavity of mold during pressing cycle. Pressing cycle includes, at least, one period of gradual progressive deformation, then, at least, one period of letting it stand with heating. Use is made of mold with, at least, one narrowing in closed position designed for restriction of extruded side flow of softened material of semifinished product. Narrowing is located so as to prevent defects of shaped product. EFFECT: provided formation of complicated profiles whose radius of bending below board thickness. 26 cl, 16 dwg
