A structural component for a vehicle may include a compression member that is compressed into a first state and then expanded into a second state. The extrusion in the first state has a reduced dimension relative to a desired final dimension. The extrudate in the first state is placed within a mold defining a desired final dimension. The pressurized water is distributed within the interior unit of the extrusion in the first state such that the wall defining the interior unit expands into engagement with the surface of the mold, creating a surface feature or sealing interface with strict tolerances. The relative shape of the mold and the extrusion in the first state defines an open space between the mold and the extrusion into which the extrusion can be expanded to define a final shape. Some of the internal units may be clogged such that these internal units are not provided with pressurized water.

    一种用于车辆的结构部件,该结构部件可以包括挤压件,该挤压件被挤压成第一状态并且然后扩张成第二状态。处于第一状态的挤压件相对于所期望的最终尺寸具有减小的尺寸。处于第一状态的挤压件被放置在限定所期望的最终尺寸的模具内。加压水分布在处于第一状态的挤压件的内部单元内,使得限定内部单元的壁扩张成与模具的表面接合,从而产生具有严格的公差的表面特征部或密封界面。模具和处于第一状态的挤压件的相对形状在模具与挤压件之间限定了开放空间,挤压件可以扩张到该开放空间中以限定最终形状。内部单元中的一些内部单元可以被堵塞,使得这些内部单元不被提供加压水。
