Abstract

PURPOSE: To shorten the production process and to improve the product accuracy, by melting a powdered plastic in a rotating mold under heating, and by pressing the plastic by centrifugal force.
CONSTITUTION: A powdered plastic is fed from the inlet 7 to the molding chamber 5 of the rotating mold 4 connected to the rotating shaft 2 of the motor 1, and molded centrifugally while being molten by the heater 8. Uniform molding pressure prevents internal defects and strains. The higher number of revolutions of the mold 4 permits the molding of even a high-viscosity melt, and optional change in wall thickness of the molded article in the same mold is possible by a change in the plastic input.
