Abstract

A method for production of a molded part made of plastic by rotational molding includes placing a starting material in a form of at least one of a plastic or a plastic precursor into a rotational melt mold that is fitted with at least one magnetic element. The rotational melt mold is rotated and, while the rotational melt mold is rotating, the starting material is shaped. The at least one magnetic element rotates together with the rotational melt mold while the starting material is being shaped. The starting material and the at least one magnetic element are configured in such a way that the starting material and the at least one magnetic element interact magnetically such that a portion of the starting material is attracted and held in place by the at least one magnetic element while the starting material is being shaped.
