In one embodiment, a vehicle energy absorber system, comprises: blow molded crush lobes that are open on one side, wherein the energy absorber comprises fillets having a fillet radius of less than 20 mm and a thickness of less than or equal to 1.5 mm; a bumper beam adjacent the open side; and a fascia, wherein the energy absorber is located between the fascia and the bumper beam. In one embodiment, a method for making a blow molded energy absorber comprises: introducing a molten plastic to a first mold cavity; introducing gas into the plastic to conform the plastic to the interior of the first mold cavity and form a first preform; and separating the first preform along a centerline thereof to form open, first preform portions having first crush lobes.

In an embodiment, an energy absorbing device comprises: a metal component comprising greater than or equal to three walls forming a metal component channel; and a plastic component having a honeycomb structure with a plurality of walls defining comb channels therein. The plastic component is located in the metal component channel forming a crash can. The plastic component is inseparable from the metal component without damage to the metal component and/or the plastic component. In one embodiment, a method of making an energy absorbing device can comprise: co-molding the metal component and the plastic component to form a crash can. The energy absorbing device can be used on a vehicle, adjacent to a vehicle component.
