A method for producing a filter element provided with a sealing part in which the sealing material is introduced into a casting chamber between two tundish parts when in the non-cured state, and a compensation space connected to the casting chamber for the expansion of the sealing material. 1. A method for molding a sealing part directly onto a filter element using a mold casting apparatus , comprising the steps of:{'b': '5', 'providing the filter element () of a filter media having a flow face and an adjacent lateral side, the flow face is an inflow face or an outflow face;'}{'b': '1', 'claim-text': [{'b': 2', '2, 'a first tundish part () of the mold casting apparatus, the first tundish part () arranged at or proximate to the filter media on the lateral side of the filter element during molding and having a tip portion projecting towards the flow face of the filter element and spaced outwardly away from the lateral side of the filter element forming an open gap therebetween;'}, {'b': 3', '3', '7, 'a second tundish part () of the mold casting apparatus, the second tundish part received directly against the filter media at the flow face of the filter element during molding, the second tundish part () spaced away from the first tundish part and spaced away from the lateral side of the filter element, wherein the flow face and sidewall of the filter element together with the spaced apart first and second tundish parts form a casting chamber () for receiving a sealing material;;'}], 'providing the mold casting apparatus () including{'b': 7', '2', '3', '5', '7, 'wherein the filter element is placed such that a filter element edge portion of the lateral side and flow face forms wall portions of the casting chamber (), such that the first tundish part (), the second tundish part () with the filter element () define the casting chamber ();'}{'b': 2', '7', '6', '11, 'wherein the tip portion of the first tundish part () in the casting chamber () defines a groove in the ...
