The invention relates to a method for producing a ring-shaped or plate-like element, in particular for a metal-sealing material-feedthrough, in particular for devices which are subjected to high pressures, for example igniters for airbags or belt tensioning devices, whereby a blank, especially in the embodiment of a wire-shaped material is provided and the blank is subjected to processing so that a feedthrough-opening can be incorporated into a ring-shaped or plate-like element created from the blank.

A method for producing a metal sleeve includes providing a first metal sleeve semi-finished product having a metal body. The metal body surrounds an inner channel. At least one groove is located in the metal body on the side of the inner channel. The first metal sleeve semi-finished product is pressed into a first die by means of a punch and in the process is formed by impact extrusion into the metal sleeve to be produced. The first die is designed such that a proximal front edge, which is spaced apart from the distal front edge and delimits the groove in the proximal direction, is formed in the metal body on the side of the inner channel. A metal sleeve includes a metal body which surrounds an inner channel running between a proximal and a distal opening. The inner channel has at least one groove set back into the metal body, running in the longitudinal direction of the inner channel and stepped on both sides by a distal and a proximal front edge. The proximal front edge of the groove is produced by impact extrusion. A method for producing a gearbox is provided.

A material dispense tip includes an elongated hole in an elongated neck that extends from an input end of the neck to an output end of the neck. The hole at the output end of the neck has a first diameter. The output end of the neck is positioned against a die surface. A punch is inserted into the hole at the input end of the neck. An external force is applied to the neck to cause the output end of the neck to be deformed under compression by the die surface, to reduce the diameter of the hole at the output end of the neck from the first diameter to a second diameter that is less than the first diameter.

A spray tip for a fluid applicator includes a stem configured to be inserted into the fluid applicator. The stem includes a stem pre-orifice portion and an insert receiving portion. The spray tip includes a pre-orifice insert having an inlet and an outlet. The pre-orifice insert is disposed within the insert receiving portion and disposed against a rearward shoulder of the stem.

A precision forging method includes arranging a metal material in a die cavity so that a distal end surface of a wall portion of the metal material is opposed toward a stopper and a bottom portion of the metal material is opposed toward a punch. Further, the precision forging method includes moving the punch, which includes a cutting blade on an edge of a working end surface, in the die cavity to cut part of the wall portion thickness-wise with the cutting blade and cause shear deformation in the cut portion.

A metal assembled body including a first member formed by forging a metal material, the first member including a peripheral wall portion in which a metal flow is formed along an axial direction and an extending portion extending from the peripheral wall portion and having an opening, the peripheral wall portion and the extending portion being formed integrally, and a closing member welded to a welding surface on the extending portion to close the opening, before the closing member is welded, the extending portion being formed to expose an end portion of the metal flow at the welding surface, and a welding position of the closing member on the welding surface being set to make a width of a first region larger than a width of a region excluding the first region, the first region being a region divided by a welding site, where arrival of a gas is inhibited.
