In a method for monitoring a functional state of a shaping tooth arrangement on a forming tool, at measurement times which are temporally staggered with respect to each other at a plurality of measurement locations on the shaping tooth arrangement, a tooth arrangement force is measured which acts on the shaping tooth arrangement. At each of the measurement times for each of the measurement locations an instantaneous local tooth arrangement force is thereby determined. A previous instantaneous local tooth arrangement force and a subsequent instantaneous local tooth arrangement force are correlated with each other to determine a local state identification value. On the basis of the local state identification values associated with the measurement locations, information is obtained relating to the functional state of the shaping tooth arrangement.

Novel recycled aluminum alloys are provided for use in an impact extrusion manufacturing process to create shaped containers and other articles of manufacture. In one embodiment blends of recycled scrap aluminum are used in conjunction with relatively pure aluminum to create novel compositions which may be formed and shaped in an environmentally friendly process. Other embodiments include methods for manufacturing a slug material comprising recycled aluminum for use in the impact extraction process.

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.

The present invention is directed to an integral planet carrier with no joints, a method of manufacturing it and an apparatus for doing so. Such integrally manufactured components have better strength than a conventionally produced multi-piece jointed planet carriers or integral planet carriers made from casting process. The present invention provides a hot forging process which can be used for the manufacturing of the planet carrier. The manufacturing process comprises of forward extrusion of a billet followed by backward extrusion. This is followed by bending operation, which is in turn followed by a flattening operation. Post-forging heat treatment and other treatments such as shot blasting follow. Finally machining is carried out to arrive at the final integrally formed planet carrier. The forward extrusion, backward extrusion, bending and flattening operations are done on a press or hammer having sufficient energy and load capacity. Preferably these operations are performed on a hydraulic press in order to achieve the required accuracy and precision.
