an insert body part having an outer shape adapted for insertion into an insert cavity arranged in the injection molding tool;
wherein the insert body part comprises at least two different polymer materials having different physical characteristics and being distributed within the insert body so that one or more first volumes of the insert body comprises a higher concentration of a first one of the two different polymer materials than in remaining parts of the insert body;
wherein one or more second volumes of the insert body comprises a higher concentration of the second one of the two different polymer materials than in the remaining parts of the insert body part; and
wherein the one or more first or second volumes define rounded, localized shapes, and the other of the one or more first or second volumes is disposed around the rounded, localized shapes.
