摘要

Rotational molding device comprising a first turret 11 carries - molds, and a second turret 12 supporting the trays to plastic powder. The powdering station 13, a powder trough of the second turret 12 is coupled to a frame 22 of the reception of the mold of the turret 11, and the assembly is driven in rotation about a longitudinal axis 23, so as to distribute the powder in the mold has been heated beforehand. A bearing 24 is mounted to pivot between an inactive position, and an active position in which it cooperates with an end-piece 27 of the frame 22 in order to straighten out independently of the sag due to the assembly carries - to - false. The percussion means 35 are able to transmit a multitude of mechanical shocks on the frame 22 of the mold during the rotation with the tank to a powder, and in the active position of the bearing 24.application: molding of plastic parts with thin walls.
