Abstract: An apparatus for forming a flange on a component is presented. The apparatus includes a mold disposed for the placement of the component thereon, a forming tool, and a tubular bladder. The forming tool is assembled to hold the component with a first portion extending into a space defined between the mold and the forming tool. The tubular bladder has a non-uniform wall thickness around its cross section along a longitudinal dimension of the bladder. The bladder is disposed in a step defined in the mold, and configured to impart a forming force to the portion extending into the space to form the flange on the component when the bladder is inflated. A method for forming the flange on the component is also provided.
