Claim:
1. A method for molding a sealing part directly onto a filter element using a two part mold casting apparatus, comprising the steps of: providing the filter element of filter media having a a flow face and an adjacent lateral side; providing the two part casting apparatus including: wherein the filter element is placed such that a filter element edge portion of the lateral side and flow face forms wall portions closing the casting chamber, such that the first tundish part, the second tundish part together with the filter element together define the open casting chamber; wherein an outer side of the first tundish part as spaced away from the second tundish part forming an open compensation space between the tundish parts into which the casting chamber communicates; wherein the tip portion of the first tundish part in the casting chamber defines a sealing surface of the sealing part; wherein the second tundish part in the casting chamber has a recess for defining an second sealing surface of the sealing part; casting the sealing part by steps of: wherein a compensation end face is formed on the sealing material projecting into the compensation space has a geometry which varies according to amount of sealing material used and therefore is not a sealing surface; wherein the casting chamber is arranged so that the sealing surface, the opposing sealing surface are formed on opposite chamber walls of the sealing part; wherein the compensation end face of the sealing part projecting into the compensation space differs from the sealing surface, the opposing sealing surface and a further sealing surface.
