Plastic molding process and its preparation

The invention relates to a method for producing a molded part, in particular container, from plastic by rotational molding, wherein a starting material (6) in the form of a plastic or plastic precursor in a rotational molding mold (1) are introduced and rotation of the rotating fusion mold (1) is formed, wherein the rotating fusion mold (1) with at least one magnet member (4, 13) is provided. The starting material (6) and the magnetic element (4, 13) are formed such that the starting material (6) and the magnetic element (4, 13) enter into magnetic interaction and a part of the starting material (6) during molding (of the magnetic element 4, 13 is tightened), and recorded. The invention further relates to a correspondingly produced molded plastic part.
