PURPOSE:To provide a superior durability and an enhanced working efficiency without impairing the beauty of a product by a method wherein in integrally producing a light-weight decorative panel made of a surface decorative layer, an adhesive layer, and a light-weight panel substrate using a table vibrator, the panel is vibration formed at a prescribed vibration acceleration. CONSTITUTION:A three-layer light-weight decorative panel made of a surface decorative layer 2, an adhesive layer 3, and a light-weight panel substrate 4 is integrally produced using a table vibrator in which pedestals 8 with motors 7 fixed and a frame 6 are vibrated by rotating weights fixed to a shaft of the motor 7 at its both ends. In this invention, firstly the frame 6 is set on the pedestals 8 of the table vibrator, the light-weight panel substrate 4 is temporarily set on the frame 6, and the table vibrator is adjusted so that the frame can be vibrated at an acceleration of 0.5-5g and a frequency of 6000-9000rpm. In this manner, in producing a three-layer light-weight decorative panel, the panel is vibration formed at a vibration acceleration of 0.5-5g. |
