Abstract: A retention clip includes a first clip arm that defines a fastener bore and includes at least one retention finger that extends into the fastener bore. The retention clip also includes a second clip arm spaced apart from the first clip arm. The second clip arm includes a nut having a bore coaxially aligned with the fastener bore and configured to receive a fastener.

Abstract: A paint bell cup for directing a spray of paint onto a surface includes a cup body having an outer surface, an inner conical surface having a circumferential edge, and a stem extending from the outer surface. The stem includes a passage that delivers paint toward the inner conical surface. The cup body includes one or more spray control features that extend along the inner conical surface toward the circumferential edge. The one or more spray control features promote a selected uniform droplet size of the paint traveling from the stem toward the circumferential edge.

Abstract: A method of repairing an ultra-large single-piece cast component of a vehicle body. The method includes the steps of locating a damaged portion of the cast component, determining an extent of the damaged portion of the ultra-large cast component, defining a cut-line sectioning off the damaged portion from an undamaged portion of the ultra-large cast component, cutting along the cut-line to excise the damaged portion from the undamaged portion of the ultra-large cast component, and joining a replacement piece to the undamaged portion of the ultra-large cast component. The replacement piece is fabricated based on the original manufacturer’s geometry and dimensional data of the excised damaged portion. The undamaged portion of the ultra-large cast component remains on the vehicle body during the repair.

Abstract: An engine for a vehicle. The engine includes a cast engine block having a hybrid insert disposed in a fastener bore having rolled internal threads. The hybrid insert includes an internal surface having cut inner diameter (ID) threads and an external surface having rolled outer diameter (OD) threads. The rolled OD threads of the hybrid insert are received in the rolled internal threads of the fastener bore. The hybrid threaded insert may include a bi-metal in which the ID threads are formed of one metal alloy and the OD threads are formed of another metal alloy. Alternatively, the external surface of the hybrid insert may define locking features and the engine block is cast onto these locking features, thereby locking the hybrid insert to the engine block.

Abstract: An in-mold coating includes graphene and a base material including an unsaturated polyester and/or a vinyl ester monomer. A part includes a main body formed of a polymeric sheet molding compound and an in-mold coating disposed on the main body, where the in-mold coating includes graphene and a base material that comprises an unsaturated polyester and/or a vinyl ester monomer. A method of creating an in-mold coating includes providing a base material comprising at least one of an unsaturated polyester and a vinyl ester monomer, and the method further includes adding graphene to the base material.
