Abstract: The invention relates to a method for producing a component, said method comprising the steps of: providing a dimensionally stable carrier which comprises a first through-opening and a second through-opening; attaching the dimensionally stable carrier to a first mould half, wherein a sprue cavity is formed in the region of the first through-opening on the side of the dimensionally stable carrier facing the first mould half and an overflow chamber is formed in the region of the second through-opening; positioning a second mould half such that a cavity connecting the first through-opening and the second through-opening is formed at least in sections between the second mould half and the dimensionally stable carrier, and introducing a material into the sprue cavity.

Abstract: An inflatable sealing device includes a bushing and a plunger which is movably guided in the bushing through application of air pressure from an air supply to execute a predefined limited stroke. A sealing tube is connected to the plunger and has an interior space which is connected to the air supply to radially expand the sealing tube when air pressure is applied.
