The invention relates to a filling shoe () for filling a molding cavity () of a pressing mold with a powder, comprising a casing () with at least one filling cavity () having at least one side wall, wherein at least one filling opening (), via which the powder can be introduced into the filling cavity (), is designed on the casing (). At least one stripping element () connected to a drive unit () is arranged in the filling cavity (), wherein the at least one stripping element () is rotatable.

Filling shoe

There is described a form tool for compression forming a molded body having a circular cylindrical through hole with at least one helical groove from a sintering powder, which form tool has a mantle (1) with an inserted mold core (2), which forms at least one flight (3) protruding against the mantle (1) for forming the groove of the molded body, and a ring-shaped plunger (6) engaging in the mold cavity (5) between the mantle (1) and the mold core (2). To create advantageous constructional conditions, it is proposed that the axial length of the flight (3) of the mold core (2) should correspond to the axial length of the molded body, and that the mold core (2) should have an axial web (4) continuing the flight (3), which axial web engages in an adapted axial groove of the ring-shaped plunger (6).

A method of producing a sliding sleeve for a synchronizer of a speed-changing gear, the sliding sleeve being comprised of a sintered powder metal compact having a claw extending along an inner periphery of the sleeve, and the claw consisting of teeth having opposite end faces and a cross-section between the end faces which is reduced relative to an undercut portion at at least one of the end faces, which method comprises the steps of sintering the powder metal compact having the claw consisting of the teeth having the opposite end faces and the reduced cross-section extending between the end faces, and then applying solely an axial upsetting force to the one end face to form the undercut portion thereat while leaving the reduced cross-section unchanged.
