ABSTRACT:
A technique for sealing a housing (10) is disclosed characterized by use of a multi-stage tool (50) specifically adapted to progressively cold roll and crimp seal one or more flanges (18) formed on a component (12) over a beaded edge (24) which, in one embodiment, may be formed on another component (14). The multi-stage tool (50) includes a series of laterally spaced roller dies (56A,56B,56C) configured to structurally support desired walls (15,16) of one or more of the components (12,14) during the process as well as progressively roll form and crimp the flanges (18) about the beaded edge (24) of the component (14).
