Metal rib overmolding joining including creating geometrical features in reinforcements for interconnecting a three-dimensional metal reinforcement to a metal base plate of an overmolding part in order to transfer load forces. Interlocked reinforcement is pre-assembled or assembled in an injection molding tool. Geometric features are positioned and joined creating a connection geometry that is overmolded. The joints created between the metal reinforcements are done without a welding process.

Metal rib overmolding joining

A three-dimensional overmolding and process for manufacturing same. The three-dimensional overmolding has a three-dimensional structure with overmolding, which gives significant performance benefits. Assembly and joining of reinforcements is done before the overmolding or in the injection molding tool. The three-dimensional overmolding meets predetermined structural requirements without requiring secondary operations and at a lower mass and cost. The structural benefits are due to the three dimensional shape in combination with the benefit of the overmolding process.

Three dimensional overmolding

A liftgate () formed with a thermoplastic which is overmolded around preselected reinforcements at stress points, such as a corner area, which includes a pair of separate reinforcement plates () and wherein a 3-dimensional reinforcement plate () is connected between the pair of separate reinforcements (). Preferably the 3-dimensional reinforcement plate is connected to three reinforcements.

Overmolding assembly reinforcement bracket

A liftgate having an overmolded hinge point comprising a metal reinforcement overmolded with a polymer and having a compression limiter portion molded in. The compression limiter portion including a tubular portion for receiving a fastener encapsulated during overmolding and having overmolded gusset ribs extending therefrom during the overmolding process.

Revised mounting point

A liftgate assembly having finished show surfaces, and process of manufacturing same. The liftgate assembly includes local reinforcements that are overmolded to first reinforcements, and the first reinforcements are infrared welding to a first panel. Second and third reinforcements are also infrared welded to the first panel. To infrared weld the respective reinforcements to the first panel in predetermined locations with respect to the first panel, nesting structures are provided to hold the respective reinforcements and first panel. At least one infrared heating fixture heats various predetermined surfaces on the reinforcements and first panel, and the parts are then pressed together for joining the predetermined surfaces of the respective parts together. The process is repeated, if needed, until all of the reinforcements are infrared welded to the first panel. Outer panels are bonded to the second and third reinforcements.
