A manufacturing method for an electric wire having a terminal includes a step of connecting a plurality of core wires by an ultrasonic connection process to form a connected core wire. In the step, the core wires are formed into the connected core wire having a cross-sectional shape having a width and a height in a plane orthogonal to an axis of the connected core wire, the width is not longer than a length obtained by subtracting two times a thickness of the terminal from a width of an arch groove of a crimper of a crimping apparatus in a state that a space between a support surface of an anvil of the crimping apparatus and the arch groove defines a predetermined crimped shape.

A device and method for making a wire basket, the device having a spinning fixture with a top plate with an outer periphery, arms attached at a top end at the periphery of the top plate and projecting downwardly, such that bottom ends of the arms collectively form a circular arrangement having a diameter greater than the diameter of the top plate, a means for guiding wire onto the spinning fixture such that the wire is wound onto the spinning fixture in a preselected pattern, and contacts to maintain the wire onto the spinning fixture in preselected locations, and the method including providing an apparatus for delivery of wire through a wire feed and for translating the wire feed lineally along a traverse, providing a spinning fixture for winding wire thereon, and winding a preselected pattern of wire onto the spinning fixture by translating the wire feed along the transverse.

A system of forming a bimetal medical device from dissimilar metal components includes a first metal component, a second metal component, a retaining device, a compression mechanism, and an energy source. A method of forming the bimetal medical device with the system includes applying a first pulse of laser energy to a joint formed between the first and second metal components retained by the retaining device and compressing the first and second metal components together with the compression mechanism to form a welded region.

The present invention seeks to enable a band-shaped metal wire member to be stably accommodated within a die. A die is prepared that includes a bottom die provided with a depression and a top die provided with a projection that can be arranged within the depression so as to close off a space above the depression. An inner surface of the depression includes a central die surface formed at a width-direction center of a base of the depression and a pair of curved guide die surfaces provided continuous with two sides of the central die surface and curved so as to project outward. The central die surface is formed as a flat surface or as a surface that curves more gently than the pair of curved guide die surfaces. A bonding process portion of a band-shaped metal wire member is folded in two and arranged within the depression.

The present disclosure relates to an automatic forming machine for plant growth supports, comprising a ring rolling system with a ring rolling unit, a mold system with a mold unit, and a welding system, which are all disposed on a machine frame, wherein the ring rolling unit can roll a metal wire and make the metal wire be formed into a ring with an opening in the mold unit; the mold system is for carrying the ring and making two free ends of the ring with an opening aligned or alternately overlap with each other; the welding system welds can weld the opening of the ring carried by the mold unit, causing the ring to become a closed ring. The present disclosure has a high automatic degree and can reduce the production time and labor cost.
