A method of manufacturing a chain link (8) of an abrasion cutting chain comprises: providing a metal blank with outer contours of the chain link (8) and rivet holes (14); and providing a ring (15) of a seal material by injection-molding of seal material around at least one rivet hole (14). The method further comprises providing a transfer channel (16) in the metal blank adjacent to at least one of the rivet holes (14). The seal material flows via the transfer channel (16) into at least one cavity portion of an injection mold assembly to form at least one rings (15) of seal material. An abrasion chain link comprises at least one rivet hole (14). A transfer channel (16) is provided next to the rivet hole (14).

The present disclosure provides a winding device for producing a fiber composite loop chain and a winding method, and belongs to the field of production equipment. The problem that an existing composite loop chain forming technology has tension defects is solved. The winding device includes a main shaft assembly, a clamp pushing-in mechanism, travel switch assemblies, a mold pushing mechanism, a clamp pulling-out mechanism, a positioning and clamping mechanism and a tension control mechanism which are fixedly connected to a rack. The main shaft assembly includes a driving mechanism, a bearing pedestal, a rotating main shaft, clamp sliding shafts and a supporting block. The driving mechanism is connected with one end of the rotating main shaft, and the other end of the rotating main shaft is connected with the supporting block. The rotating main shaft is connected with the bearing pedestal through a bearing, and the bearing pedestal is fixed to the rack. Two clamp sliding shafts are provided. The two clamp sliding shafts are symmetrically arranged along the rotating main shaft and are in sliding connection with the supporting block, and clamps are installed on the clamp sliding shafts. The winding device and the winding method are mainly used for producing the fiber composite loop chain.

An injection-moulded plastic part for a cable carrier, particularly a side part of a chain link produced in an injection moulding process. The injection moulded part has a visible, identifiable marking on a first side, particularly the outside. The at least one marking comprises a data code marking having a 2D code for data encoding which is introduced into the plastic body directly in the injection moulding process so that said marking is provided on the first side to be machine-readable. The invention likewise relates to a corresponding injection moulding tool having a number of first symbol regions and second symbol regions for producing the data code marking in the injection moulding process.
