Abstract
A structural component for a vehicle may include an extrusion that is extruded into a first state and then expanded into a second state. The extrusion in the first state has a reduced size relative to a desired final size. The extrusion in the first state is placed within a die that defines the desired final size. Pressurized water is distributed within internal cells of the extrusion in the first state such that the walls defining the internal cells are expanded into engagement with the surface of the die, thereby creating surface features or sealing interfaces with tight tolerances. The relative shape of the die and the extrusion in the first state defines an open space therebetween, into which the extrusion may expand to define the final shape. Some of the internal cells may be plugged such that they are not provided with pressurized water.
