Abstract: Electrically conducting electrodes, are produced using an injection molding unit with a plastifying worm and a nozzle that delivers the material. <??>A process for producing electrically conducting electrodes, especially bipolar plates for fuel cells, comprises injection molding using a unit which has a plastifying worm (16). The material molded is a compound material which uses polymeric plastic as a binder, and more than 80wt% of a powdery electrically conducting material e.g. graphite etc as the filler material. The plastifier delivers the material via a nozzle which is less than 15mm in length. The injection molding unit flow path does not reduce in cross section from the supply point to the mould, by more than 10:1 especially 5:1. The compression ratio in the plastifier worm is no more than 1.6:1, and is between 1:1.2 and 1:1 for duroplasts. The electrodes are formed by injection stamping.

Abstract: The plastic material injection-moulding unit has a supply unit (granules hopper B), arranged on the supply block (10), for feeding the material to be processed via a chute (11) into the plasticising cylinder (15). The supply unit (B) is held by a carrier element (24).

The guide rail (18) is arranged along the and symmetrically to the vertical plane of symmetry of the injection-moulding unit. Such an arrangement achieves the effect that, with a substantially symmetrical construction, the centre of gravity of the supply unit in the emptying position lies in the vertical plane of symmetry of the injection-moulding unit or is in fact very close to it, it being possible for the transferring of the supply unit (B) into the emptying position to be performed approximately in the plane of symmetry.
