Abstract
The invention relates to a method for producing a plastic chain link, which has interspaced plates (10, 11) as well as lower and upper cross-connecting elements (15) that connect said plates, whereby at least one cross-connecting element is connected to one of the plates (10) in an articulated manner. According to the invention, at least one of the plates is firstly produced followed by the production of at least one of the cross-connecting elements while simultaneously forming a joint connection between one of the plates and one of the cross-connecting elements.
