A method and apparatus for manufacturing a welded resin article which includes (a) bringing first and second resin members to come into contact with each other; (b) applying laser light to the first and second resin members while moving the laser light relative to the first and second resin members; (c1) obtaining a value corresponding to the intensity of infrared light from a plurality of locations on a surface; (d) successively calculating, as a section average, the average of a predetermined number of successive values, among those obtained from the plurality of locations corresponding to the intensity of the infrared light; (e) a step of successively calculating a deviation judgment value; and (f) a step of successively judging whether or not the deviation judgment value falls within a predetermined judgment threshold range.

A method for assembling a skin and a flange of a stiffener. The periphery of the contact between the skin and the flange of the stiffener is sealed by applying a bead of adhesive on the flange of the stiffener in contact with the skin. A first and second orifices are made in the skin. The orifices open at the interface between the skin and the flange of the stiffener. The adhesive is injected through the first orifice at the interface between the skin and the flange of the stiffener while keeping the skin in contact with the stiffener until the interface between the skin and the stiffener is completely filled with the adhesive.

A method for forming a hybrid heat exchanger is provided. The method includes laser-texturing a metal surface to create a plurality of microstructures and subsequently melt-bonding a plastic component to the plurality of microstructures. During melt-bonding, plastic material penetrates the plurality of microstructures and conforms to the plastic component to the metal surface. After hardening inside the microstructures, the plastic component adheres to the metal surface as a hybrid component. As a result, a fastener or snap connection is not required, and the plastic-metal joint provides a barrier to water, glycol-based fluids, air, and other fluids.

The present invention relates to devices with which, for example, narrow surfaces of preferably plate-like workpieces can be provided with a coating material. The device includes a laser for outputting a laser beam to a laser beam emitter, wherein the laser beam is directed onto the coating material or onto the workpiece in such a manner that the laser beam forms a plane of reference with solder on the surface of the coating material or the workpiece.

The present invention is provided with: an insulation holder formed of a thermoplastic resin material and having a first opening; a wire connection ring formed of a thermoplastic resin material and having a second opening; and a joining component inserted astride in the first opening and the second opening, the joining component being formed of a metal material having a higher melting point than those of the thermoplastic resin materials, the joining component having a higher stiffness than those of the insulation holder and the wire connection ring, wherein a welded part is formed by welding in at least a part of an area where each of the Insulation holder and the wire connection ring has contact with the joining component.

A protrusion on a first member made of synthetic resin wherein a laser beam is applied to a side surface of the protrusion in a state in which a top surface of the protrusion of the first member is abutted against a second member made of synthetic resin, so as to melt at least the entire top surface of the protrusion and melt a portion of the second member in contact with the protrusion by heat of the melted top surface of the protrusion, followed by solidification of the melted portions, whereby the first member and the second member are welded together.

A vehicle grille includes: a grille panel; a lens panel disposed at a rear side of the grille panel, formed in a same shape as some or entire area of the grille panel, and, when a light is incident, configured to allow some of the light to propagate in the lens panel and emit some of the light to an outside of the lens panel; and a housing disposed on a rear surface of the lens panel, formed in a same shape as the lens panel, and including a coupling provision hole configured to allow a front surface of the lens panel to be coupled to a rear surface of the grille panel at a rear side of the lens panel, wherein the rear surface of the lens panel and a front surface of the housing are coupled at the front side of the lens panel.

An edge trim for pieces of furniture, including a meltable layer, is described. The molecular structure of the meltable layer contains both polar and non-polar parts. By way of a non-limiting example, an edge trim for pieces of furniture having an exposed edge of wooden or wood substitute material is described, comprising a molten layer and a structural layer, wherein the structural layer and the molten layer are connected in an adhesive bond, wherein the molten layer is made of a material that is chemically modified such that polar and non-polar components are found in a single molecular structure, wherein the molten layer contains energy absorbing additives, wherein the energy absorbing additives of the molten layer are selected from the group consisting of metal oxides, metal phosphates, metal salts of organic anions and combinations thereof.

The present technology discloses a system, for joining workpieces using energy, such as ultrasonic energy, where the energy concentrates at a location within a weld area, promoting sequential melting of a plurality of energy directors. The system can be configured so that the sequential melting begins at the center of the weld area and progresses outwards. Sequential melting may occur through use of a welding tip configured to reduce air pockets, a tapering the height of a plurality of energy directors, and/or tapering the energy directors themselves, all of which reduce the size of an energy transfer area produced by thermal energy. The present technology also includes a method for joining workpieces using energy such as ultrasonic energy that concentrates at a location within a weld area causing sequential melting of a plurality of energy directors using the aforementioned features.
