Abstract
The invention relates to a method for producing an assembly (1) consisting at least of a first component (2) and a second component (3), the first component (2) being arranged at least partly inside the second component (3), and the first component (2) and the second component (3) being produced from at least one metal sintering powder according to a sintering method comprising the steps of powder pressing and sintering. The first component (2) and the second component (3) consisting of the at least one metal sintering powder are pressed together in a mold to form a one-piece green compact (4) and the two components (2, 3) are only separated after sintering.

A method for producing an assembly (1) comprising at least a first component (2) and a second component (3), the first component (2) being arranged at least partly inside the second component (3), and the first component (2) and the second component (3) being produced from at least one metal sintering powder according to a sintering method comprising the steps of powder pressing and sintering, wherein the first component (2) and the second component (3) comprising the metal sintering powder are pressed together in a mold to form a one-piece green compact (4) and the two components (2, 3) are only separated after sintering.
A press mold (7) for producing a green compact (4) for an assembly (1) comprising at least a first component (2) and a second component (3), with a mold cavity for receiving at least one sintering powder, wherein the mold cavity comprises a first mold cavity (23) for the first component (2) and a second mold cavity (24) for the second component (3), wherein the first mold cavity (23) is separated from the second mold cavity (24) by at least one mold wall (25), and wherein the first mold cavity (23) is also surrounded at least partly by the second mold cavity (24), and wherein in the mold wall (25) separating the first mold cavity (23) from the second mold cavity (24) at least one opening (26) is formed, by means of which the first mold cavity (23) is connected to the second mold cavity (24).
The press mold (7) for producing a green compact (4) for an assembly (1) comprising at least a first component (2) and a second component (3), with a mold cavity for receiving at least one sintering powder, and a pressing punch (27), wherein the mold cavity comprises a first mold cavity (23) for the first component (2) and a second mold cavity (24) for the second component (3), wherein the first mold cavity (23) is separated from the second cavity (24) by at least one mold wall (25), and wherein in a base area of the mold cavity and/or the pressing punch (27) at least one depression (30) is formed by means of which the first mold cavity (23) is connected to the second mold cavity (24).
