Various embodiments relate to plastic-metal junctions and methods of making the same via laser-assisted joining. The present invention provides a method of forming a junction between a metal form and a solid plastic. The method can include laser treating a surface of a metal form to generate a feature (e.g., a plurality of at least one of pores and grooves) in the surface of the metal, wherein the laser has an angle of incidence with the surface of the metal of other than 0 degrees. The method can include contacting the metal surface including the feature with a flowable resin composition. The method can include curing the flowable resin composition to form the solid plastic, to provide the junction between the metal form and the solid plastic.

A water-using household appliance, in particular a household dishwashing machine, includes a wall which is made from a metal material, and a device which is made from a plastic material and fixedly connected to the wall by a laser weld.

A joint between at least one element of metal material and at least one element of plastic material is obtained by pressing these elements in contact against each other, with a simultaneous application of heat. A cladding of metal material and/or of plastic material is applied above the joint by additive manufacturing technology.

A light, durable, and user friendly cover for a laptop computer that integrates the protective qualities of hard shell cases with the aesthetics of soft cut-and-sew covers is disclosed. The cover includes top and bottom panels configured to cover the display and keyboard portions, respectively. Each panel is independent and separate from the other and each is formed as a unitary component of a molded resilient polymer material, such as polycarbonate, that is configured to reversibly and retentively snap-fit over the outer surface of the laptop computer. Each panel includes a raised lip along its perimeter edge region that defines an internally extending recessed region on the panel's outer surface. Fabric and/or leather overlays are positioned, sized and adhesively coupled atop the recessed regions and are protected from delaminating, fraying, and/or peeling by the raised perimeter lip.

An optical element includes an optical material including a first edge and an opposing second edge. The optical element further includes a plurality of micro-channels arranged within the optical material. Each of the micro-channels of the plurality of micro-channels extends from the first edge to the second edge of the optical material.

A welded joint between at least one metal material element and at least one thermoplastic material element is obtained by pressing the elements against each other while applying heat. Contact surfaces of the metal material, which are in contact with the thermoplastic material, are provided with uneven surface portions having a distribution of asperities. With heat applied, the thermoplastic material fills spaces between these asperities and maintains this configuration after subsequent cooling, thereby improving strength of the joint. The uneven surface portions are obtained in a preliminary forming step of the metal material in a press mold, which is configured with a forming surface for generating the uneven surface portions by mechanical deformation and/or with a device for guiding a laser or electron beam. By this technique, hybrid components are obtained made of one or more elements of metal material between which a shaped component of thermoplastic material is interposed.

A surface of a metal substrate formed from a metal is heated, an oxide film is formed on the surface of the metal substrate, at least a portion of the oxide film is heated so as to increase a joining strength of the oxide film to the metal substrate, subsequently a synthetic resin substrate formed from a synthetic resin is joined to the oxide film, and thus a metal-resin joined body is obtained. Thereby, a metal-resin joined body having high joining strength is obtained.

The present invention provides polymer-metal composites free of adhesives and methods of making same. In particular, the present invention takes advantage of a unique metallic bonding surface created by exposure to a laser whereby micron-sized fragments are fixed to the metallic bonding surface such that a high strength bond with polymeric material is created upon exposure to a second laser.

It is provided an electronic control device including a resin molded body, a metal body, and an electronic component, wherein the resin molded body and a main surface of the metal body are bonded, and at least a part of a side surface continuous to the main surface of the metal body is in contact with a side contact portion provided in the resin molded body.

A method for manufacturing a rivet connection of a fiber composite component. The method includes positioning a first component which contains a fiber composite material in an overlap joint with a second component, laser-drilling a shared through-hole at least through the fiber composite material of the first component, inserting a rivet into the through-hole and fixing the rivet to the first and to the second component.
