An injection molding process method of a plastic part on a metal shell to form a high-strength combination comprises: forming a molding cavity which is inwardly concave from the outer surface and extending through flanges at periphery of the metal shell to area beneath bridges protruding from flanges, the bridges being removed after the injection molding. A plastic part with slight deformation is in the molding cavity and is tightly combined with the metal shell due to the bridges. The protruding bridges can be removed from the flanges by milling or cutting without damaging the plastic part, thus the plastic part does not require to be remachined, and the appearance of the metal shell is not affected.

A system includes a first horn, a first ultrasonic transducer, a second horn, a second ultrasonic transducer, a memory, and a controller. The first horn includes a first part-interfacing surface. The second horn includes a second part-interfacing surface and is positioned relative to the first horn such that a part to be welded can be positioned between the first and second part-interface surfaces. The controller is configured to cause a first ultrasonic energy to be applied through the first horn via the first transducer to cause the first part-interfacing surface to vibrate, cause the first horn to move in a first direction at a first time, cause a second ultrasonic energy to be applied through the second horn via the second transducer to cause the second part-interfacing surface to vibrate, and cause the second horn to move in a second direction at the first time.

A method for producing metal-polymer composites which include at least one metal part and at least one part made of a polymer composition, the method including the steps of: treating the surface of at least one metal part at least partially with a solution of triazine thiol derivative to obtain a treated metal surface; and contacting the treated metal surface at least partially with at least one polymer composition so as to obtain a metal-polymer composite, wherein the polymer composition includes at least one semi-crystalline polyamide. Also, a metal-polymer composite that includes at least one part made of a polymer composition and at least one metal part and that is obtainable by the method and to a product including the metal-polymer composite.

A torque converter includes an impeller, a turbine, a stator, a one-way clutch, and an insert molded thrust washer formed onto a retention mount that is integrally formed on one of the impeller, the turbine, the stator, and the one-way clutch. The retention mount defines an undercut. At least a portion of the insert molded thrust washer is disposed within the undercut. Interference between the retention mount and the insert molded thrust washer mounts the insert molded thrust washer to the retention mount.

The present application relates to a polymer composition comprising from 20 wt % to 30 wt % of a polycarbonate; from 40 wt % to 60 wt % of a polybutylene terephthalate; from 5 wt % to 30 wt % of a reinforcement fiber; from 1 wt % to 10 wt % of glass bubbles, and from 0.3 wt % to 2 wt % of transesterification inhibitor, all contents are based on the total weight of the composition. The polymer composition according to the present invention has improved adhesion to the metal (especially aluminum), even after annealing and anodizing processes are applied.

A thermoplastic surfacer for providing lightning strike protection to a composite component of an aircraft, methods of manufacturing the surfacer, and methods of applying the surfacer to a composite part. The thermoplastic surfacer includes a broadgood having an amorphous thermoplastic resin, one or more fillers embedded into the broadgood, and a lightning strike protection mesh or foil embedded into the broadgood. When applying the surfacer to a composite part of an aircraft, the method includes draping the surfacer on an at least partially unconsolidated composite part, consolidating the at least partially unconsolidated composite part by heating the part to a temperature at or above a melt temperature of a resins used in the part and in the surfacer, and filling at least one surface defect in the consolidated part using the amorphous thermoplastic polymer resin and milled fibers provided in the thermoplastic surfacer.

A CFRP material with an Al alloy sheet attached to or a CFRTP material with an Al alloy sheet attached to is prepared by joining an Al alloy sheet with a CFRP material or a CFRTP material by adhesion or by injection molding. The surface of this Al alloy sheet and a surface of metal material such as Ti, etc., are subjected to chemical treatment. After this chemical treatment, the CFRP material with an Al alloy sheet attached to or the CFRTP material with an Al alloy sheet attached to and the metal material are inserted into a metallic mold for injection molding so as to have a gap therebetween. High crystalline thermoplastic resin is injected into this gap to join the metal material with the Al alloy sheet, thus obtaining a laminated composite.
