PLASTIC MOLDED PART AND METHOD FOR ITS PRODUCTION

摘要

A method for the production of a molded part made of plastic by rotational molding includes providing an insert element made of at least one of an absorbent and saturable material in a rotational melt mold. The rotational melt mold has at least one of a constriction and a wall that projects, in an area of an inner radius, into an interior of the rotational melt mold. A plastic precursor of the plastic intended for the plastic molded part is provided in the rotational melt mold. The plastic precursor is present as a melt in the rotational melt mold. The rotational melt mold is rotated so that the melt polymerizes and is simultaneously shaped, so that part of the melt is picked up by the insert element, and so that a wall thickness of the molded part in a finished form is increased in an area where the insert element is arranged.

1. A method for the production of a molded part made of plastic by rotational molding, the method comprising:
providing an insert element made of at least one of an absorbent and saturable material in a rotational melt mold, the rotational melt mold having at least one of a constriction and a wall that projects, in an area of an inner radius, into an interior of the rotational melt mold; providing a plastic precursor of the plastic intended for the plastic molded part in the rotational melt mold, wherein the plastic precursor is present as a melt in the rotational melt mold; and rotating the rotational melt mold so that the melt polymerizes and is simultaneously shaped, so that part of the melt is picked up by the insert element, and so that a wall thickness of the molded part in a finished form is increased in an area where the insert element is arranged.
