The present disclosure relates to a mesh container and a method of making a mesh container that has a first and a second set of opposing side panels, a bottom panel, and a rim directed outwards from the upper edges of the side panels. At least two adjacent sides panels of the container and portion of the rim directed outwardly from the upper edge of the side panels are made from a sheet metal precursor with least one perforated and a stretched portion and unstretched metal portion. The precursor is folded so that the unstretched metal portion joins the two side panels and is bent to form the rim. A notch is cut from the edge of the unstretched metal portion where it is bent at the corner formed by the two side panels.

A method of forming a metal part that includes placing a metal blank in a stamping apparatus having a first die including a plurality of metal gainers and a second die including a plurality of recesses that correspond to the plurality of metal gainers, and compressing the metal blank such that the metal gainers and the corresponding recesses provide the metal blank with regions of localized stretching. Each of the metal gainers and recesses includes a flat surface such that during the compressing of the metal blank to provide the metal blank with the regions of localized stretching, a strain exerted on the metal blank by the metal gainers and recesses is less than a strain exerted on the metal blank by metal gainers and recesses that do not include the flat surface.

A flat routing material includes a flat conductive material and an insulating coating covering the conductive material. The routing material includes a bent portion as a part bending in an edgewise direction at a predetermined angle or more, and one or more folds extending toward the outer peripheral side of the bent portion are provided on at least the inner peripheral side of the bent portion. The folds are manufactured by press working.

The objective of the present invention is to provide an apparatus for manufacturing an elbow-shaped duct, comprising: a main body obliquely provided at the upper part thereof; a duct movement guiding part provided to rotate and vertically move; a duct vane forming part including forming jigs symmetrically formed and respectively slid in the opposite directions to be coupled to and separated from each other; a duct vane coupling part including a duct fixing member for guiding the fixing of a duct and a duct vane pressing member for coupling upper and lower vanes of the duct; and a rotary driving part rotatably provided inside the main body, and including an eccentric rotary roller having, at the upper part thereof, a cutting roller for cutting the duct and a forming roller for forming the upper and lower vanes of the duct, thereby enabling the duct to be manufactured, by loading the cylindrical duct on the movement guiding part, as is, and simultaneously performing cutting and forming to correspond to an elbow shape, and thus remarkably reduces manufacturing time.

A plate-shaped workpiece forming method of post-machining a pocket (3) on a curved inner surface of a plate-shaped workpiece (2) in a state where the plate-shaped workpiece (2) curved by a curving machine (10) is spread flat. The method includes a curving step (A) of setting a net curve radius (R.sub.0) obtained by adding a curve radius contraction amount (R.sub.1) due to spring-in to a finished curve radius (R) of a plate-shaped workpiece (2), taking into account an amount of contraction of the curve radius of the plate-shaped workpiece (2) between before and after machining of a pocket (3) due to spring-in, and curving the plate-shaped workpiece (2) so as to achieve the net curve radius (R.sub.0); and a pocket machining step of post-machining the pocket (3) by flatly spreading the curved plate-shaped workpiece (2).

Embodiments of an apparatus, and a method for crimping expandable stents or prosthetic valves having a radially expandable and compressible annular body and one or more protruding anchors extending from the body using the apparatus, where the apparatus comprise a housing, a plurality of circumferentially arranged nesting jaws, and an actuator configured to move the jaws radially inwardly to reduce the size of the crimping aperture, thereby radially compressing the annular body of the prosthetic valve or stent. In particular embodiments, a selected set of the jaws, each having a front side and a recessed portion in its front side adjacent to its inner end. The recessed portions of the selected jaws collectively are sized and shaped to receive the one or more anchors of the prosthetic valve when the annular body is positioned within the crimping aperture.
