Abstract:

A method for forming a bladder comprises providing a mold including a chamber wall having a first height and a cavity wall having a second height. The cavity wall is surrounded by the chamber wall and defines a plurality of cavities. A first sheet, a second sheet, and a gasket are provided to the mold, whereby the gasket is disposed adjacent to at least one of the first sheet and the second sheet. The mold is moved such that a peripheral portion of the at least one of the first sheet and the second sheet and the gasket are compressed by the chamber wall. A first pressure is provided between the first sheet and the second sheet through the gasket to form a plurality of chambers, and the mold is moved to a second position to seal the first pressure between the first sheet and the second sheet.
