The invention relates to a high-pressure line for conveying a fluid under high pressure to a consumer, in particular for supplying fuel under injection pressure to one or more injectors (14) of a combustion engine. It comprises a first (1), a second (2), and a third line section (3), which line sections (1, 2, 3) are flowed through successively in the intended operation of the high-pressure line and are jointly formed by a ones-piece component (4) made of metal, wherein the first line section (1) and the third line section (3) each have a smaller flow cross-section than the second line section (2) arranged between them.

A method for production of a metallic material from a semifinished metallic billet, the semifinished metallic billet including a nanocrystalline microstructure and/or an ultrafine-grained microstructure, the method including the steps of (1) subjecting the semifinished metallic billet to a rotary incremental forming process to form an intermediate wrought metallic billet, and (2) subjecting the intermediate wrought metallic billet to a high rate forming process to form a metallic product.

A tool configured to form four evenly spaced indentations having an indentation radius and four evenly spaced projections about a circumference of a generally cylindrical seamless ferrule having a ferrule radius. Each projection of the four projections has a projection height equal to or less than a height threshold. The tool includes four crimping dies. Each crimping die of the four crimping dies defines a concave crimping surface having the indentation radius. The tool also includes four limiting dies. Each limiting die is located intermediate two adjacent crimping dies of the four crimping dies. Each limiting die defines a limiting surface that is configured to limit a height of each projection to the height threshold.

A guide wire has an elongated core portion, a resin coating layer including a resin material and covering a distal portion of the core portion, and a metallic tubular member that has a lumen into which the core portion is inserted, and that is disposed so as to be in contact with at least a portion of a proximal end of the resin coating layer. The tubular member is formed in a state where the lumen is reduced in diameter by cold forging, and at least a portion of an inner surface forming the lumen has a compressive bonding surface which is compressively bonded to an outer surface of the core portion.

A radial compression mechanism incorporates an introduction funnel that truncates down to a cylindrical cavity for radial compressing articles. The introduction funnel facilities the loading of an article into the cylindrical cavity and enables incremental radial compression of articles, such as stents. The radial compression mechanism employs a plurality of compression dies that are configured radially about the cylindrical cavity and move in unison to cause the cylindrical cavity to open or close. The compression dies are coupled with a base and drive mechanism for moving them in unison. A method of loading a delivery catheter with a radially compressed article, such as a stent, includes positioning a delivery catheter over a compressed portion of an article that extends from an exit end of the cylindrical catheter. One or more drive mechanism may be used to automatically and incrementally load a compressed article into a delivery catheter.

A radial compression mechanism includes a constraining structure with a cut-out defined by a plurality of bearing surfaces. A plurality of die are carried by the constraining structure and arranged in a circular pattern about a central axis. Each die has a base side positioned in parallel juxtaposition to a corresponding bearing surface and each die is constrained to move reciprocally and linearly along the corresponding bearing surface. Working surfaces of the plurality of die cooperate to form a cavity that is movable between an open position and a closed position. A driving mechanism is coupled to at least one of the plurality of die to drive all of the die in unison between the open position and the closed position.
