Abstract: A method for manufacturing a passenger airbag housing using a continuous flow or constant cross-section process, the process will enable maximum design flexibility when multiple materials are capable of being used. The method will have a short design and tooling lead-time providing lean processing and a common footprint over a family of designs. A method of structurally reinforcing a passenger air bag housing by inserting a structural member into the continuous flow or constant cross-section process.

Abstract: A method of making a reinforced component by depositing a polymer into an extrusion deposition unit, during the plastication process a reinforcing material is deposited into the extrusion deposition unit. The amount and type of fiber is varied in order to provide a molded component with varying degrees of reinforcement and/or strength. The extrudate having a varying fiber reinforcement is deposited onto a mold core or cavity.

Abstract: Tooling and method for gas assist injection molding of plastics material into a hollowed part in which a mold chamber formed between stationary and movable mold tools is initially charged with an inert gas to provide a resistance force against the flow front of a short shot of plastics melt subsequently injected into the cavity and supplied with a pressurized assist gas so that the velocity of the flow front of the short shot expanded by the assist gas in the mold chamber is modulated by the controlled release of the retarding chamber charge gas to prevent blow out of the short shot while eliminating flow hesitation lines to improve molded part appearance and uniformity of part wall thickness.
