Abstract

Die Erfindung betrifft ein Verfahren zum Herstellen eines Gegenstandes durch Rotationsguss, bei dem eine Rotationsgussform rotiert wird, um ein Anlagern von zuvor in den Innenraum der Rotationsgussform eingefülltem Rohmaterial an der Innenwandung der Rotationsgussform zu bewirken. Das Verfahren zeichnet sich dadurch aus, dass der Innenraum der Rotationsgussform mittels einer Trennvorrichtung in wenigstens einen ersten Teilinnenraum, der einen ersten Innenwandungsanteil der Innenwandung aufweist, und einen zweiten Teilinnenraum, der einen zweiten Innenwandungsanteil der Innenwandung aufweist, unterteilt wird, und dass an den ersten Innenwandungsanteil und an den zweiten Innenwandungsanteil durch wenigstens einen Rotationsvorgang, insbesondere unterschiedliches, Rohmaterial angelagert wird.The invention relates to a method for producing an object by rotational casting, in which a rotational casting mold is rotated in order to cause raw material previously filled into the interior of the rotational casting mold to accumulate on the inner wall of the rotational casting mold. The method is characterized in that the interior of the rotational mold is divided by means of a separating device into at least a first partial interior, which has a first inner wall portion of the inner wall, and a second partial interior, which has a second inner wall portion of the inner wall, and that at the first Inner wall portion and is attached to the second inner wall portion by at least one rotation process, in particular different raw material.
