There is provided a method for producing a metal-resin composite which includes a resin member and a metal member having a roughened surface in at least a portion of the surface thereof, the resin member being joined so as to be in contact with at least a portion of the roughened surface. The method includes a step of joining the resin member and the metal member by melting the resin member with the frictional heat generated in the surface of the metal member on its side opposite to the resin member in a state where the metal member and the resin member are superposed. The method includes making adjustment so that when the roughened surface is measured at arbitrary five points by using a confocal microscope according to ISO 25178, the developed area ratio (Sdr) is 5 or more in terms of number-average value.

A three-dimensional decorative piece that is made of a thermoplastic synthetic resin and can retain bulkiness and shape by a core and a method of producing the same. The three-dimensional decorative piece includes an upper layer molded body made of an upper layer material with a metal vapor-deposited layer and having a three-dimensional shape with a convex portion formed on its front surface side through a high-frequency dielectric heating, a core formed by curing a flowable synthetic resin filled in the convex portion of the upper layer molded body, and a substrate bonded a back surface side of the core by fusion.

A sonic label welding device for welding multiple labels together using ultrasonic welding is disclosed. The sonic label welding device comprises a digital controls main menu screen which includes touch screen buttons that are utilized to go to specific screens to program the device to perform in a certain manner. For example, a user can press the cut to length button if wanting to cut a label to a specific length, or the label weld count button to specify the number of labels being sonically welded. Further, the sonic label welding device comprises a head for allowing multiple labels to be assembled under pressure and an anvil for directing the high frequency vibrations. A method of manufacturing a multi-layer care label is also disclosed.

A container blank having an article handling feature for handling the container blank as well as the flexible packages made therefrom during manufacture, and method of making flexible packages using such a feature are described herein. Also described herein is an array of flexible packages containing a common article handling feature provided by such a method.

A housing has a front surface, a rear surface, and side surface connecting the front surface with the rear surface. The housing is formed by injection molding. A first sub-passage is formed in the housing and communicates a first sub-passage inlet formed in the front surface with a first sub-passage outlet formed in the rear surface. A second sub-passage is formed in the housing and communicates a second sub-passage inlet formed in a midway portion of the first sub-passage with a second sub-passage outlet at a position different from the first sub-passage outlet. A flow rate detection unit is provided in the second sub-passage. A mold parting mark is formed in the rear surface of the housing at a position away from an inner opening edge of the first sub-passage outlet.

A method for welding a first hose end at a joint with a second hose end in a seam that extends on a circumference of the first hose end, the method comprising the steps: applying a protective layer at the joint to an inside of the first hose end; pushing the second hose end beyond the joint over the first hose end; pressing the first hose end and the second hose end together flat at the joint between two first damping jaws that are moved towards each other; welding the first hose end and the second hose end together by two first partial seams while pressed together, wherein the protective layer prevents a welding of the inside of the first hose end; releasing the first hose end and the second hose end from the two first clamping jaws after welding the two first partial seams.

A disclosed apparatus for forming a sealing portion for folding a secondary battery pouch includes: first and second pressing bars disposed to face each other with a sealing portion for folding therebetween to apply pressure for flattening the sealing portion for folding that is defined by the edge of a secondary battery pouch for sealing an electrode assembly accommodated therein; first and second pressing surfaces provided at the first and second pressing bars, respectively, and disposed to face the sealing portion for folding; and a forming protrusion formed on the first pressing surface and configured to form a folding guide line on the sealing portion for folding by pressure applied by the first and second pressing bars.

The technology relates to a heat sealing system (400). For instance, the heat sealing system may include a sealer assembly (800) including a pair of heat sealing bars (830, 840) configured to generate heat seals. The heat sealing system may also include a positioning (900) assembly including a platform (910) and a motor (952). The sealer assembly may be mounted to the positioning assembly, and the motor may be configured to move the sealer assembly towards and away from an edge of a table (1600).
