摘要： In an extrusion tool—in particular a disk-shaped pressing die with at least one shaping opening for the extrusion of metal such as aluminum or an aluminum alloy—comprising a steel material—in particular a low-distortion hot-working steel—with a surface coating, the coating on the extrusion tool is made from coating material which is selected from the group containing carbides, nitrides, oxides and combinations of those substances, wherein the coating material is applied to the extrusion tool by a CVD-process.

摘要： A forming tool for extrusion has a die (5), which has a forming cavity (6) having at least one critical reference value. The die (5) is surrounded by a biasing ring (8), which bears against it with radial pre-stress. The die (5) and the biasing ring (8) have tampered contact surfaces (11) and are displaceable relative to one another. The biasing ring (8) is surrounded by a reinforcement (9), which bears against it with radial pre-stress. The biasing ring (8) and the reinforcement (9) are mounted in a fixed position on a carrier (housing 1). The die (5) is displaceable relative to the carrier and capable of being locked, by locking means (15, 19) on the carrier, in positions that can be selected. By that means it is possible subsequently to carry out a fine adjustment of the critical reference value over a wide correction range.

摘要： A die for reducing the formation of flash on parts includes a first die section and a second die section defining therein a cavity. The first die section includes a pair of first surfaces and the second die section includes a pair of second surfaces which together define a pair of parting lines which extend from opposite sides of the cavity. Desirably, the first die section includes a pair of lands, each extending along the length of one of the parting lines. Each land defines a first surface portion of the first surface and is sized and configured so that the land is elastically loaded, e.g., substantially equal to and less than the elastic limit of the material forming land when forming a part. In another embodiment, a die for reducing the formation of flash includes a land sized and configured so that when a first die section and a second die section are clamped together for forming the part, a second surface portion of the first surface of the first die section engages a second surface of the second die and the stress on the first surface portion is substantially equal to and less than an elastic limit of the land. In a third embodiment, a die includes a first die section and a second die section having a first surface and a second surface, respectively, which together define a parting line having at least one bend for controlling the formation of flash. Methods for forming such dies and methods for forming parts having reduced or controlled formation of flash are also disclosed.
