ABSTRACT:
A process for controlling the shrinkage behavior during the original shaping of plastics during the manufacture of a plastic shell, especially a bearing shell for a ball-and-socket joint, wherein liquefied plastic is introduced between an inner mold (3) and an outer mold (2) in order to be cured therein, wherein the plastic is partially fixed on the outer mold (2) during the curing. This process can be preferably used in a device for controlling the shrinkage behavior during the original shaping of plastics, which has a casting mold, which accommodates at least one outer mold (2) and an inner mold (3) inserted into same, wherein the liquefied plastic (1) to be molded can be introduced between the mold parts (2, 3), wherein means for fixing the liquid plastic (1) are formed on the outer mold (2).
