FIELD: technological processes.
SUBSTANCE: head comprises body with mandrel installed in it, channels of profile section with supplying channel and magnetostrictive radiator. Mandrel is arranged as knocked-down, of rectangular shape, with cooling system. Between mandrel and rectangular sections of body there are shaping channels of profile section arranged with trapezoidal front surface. On upper and lower plane of head body there are magnetostrictive radiators of ultrasonic oscillations installed.
EFFECT: provision of possibility to increase efficiency and quality of lining wall panels due to even penetration of ultrasonic oscillations directly to the whole mass of polymer.
