摘要

A method for producing a tight housing, consisting of two shell-shaped housing parts (1, 2) consist of injection molded plastic with two precast, essentially around the entire circumference of the extending flanges (23, 24), wherein during the production of the housing parts (1, 2) in the flanges (23, 24) through openings (25) are mounted, in the joining of the housing parts (1, 2) are located opposite one another in pairs, and wherein the two housing parts (1, 2) into an injection mould (26, 27) and there be inserted after the closing of the injection mould (26, 27) with a the flanges (23, 24) and surrounding the passage openings (25) which penetrate the plastic bead (28) on the outer side of the housing are encased by molding, with wall portions of the two housing parts (1, 2) is provided with an orifice (33) into the interior of the housing form, characterised in that, in the region of the mouth (33) at least one of the outside to the inside of the housing extending flow path is provided and that, during the casting by the flow path of plastic material of the plastic bead into the interior of the mouth and is there a ring (36) with a continuous surface forms.
