Patentansprüche:Patent claims: 1. Sinterverfahren für Metail- bzw. Metallkeramik-Preßkörper, die mindestens eine Schrägfläche aufweisen, insbesondere für Endstücke von Werkzeugen, dadurch gekennzeichnet, daß der Preßkörper (2) in einer Sinterform (1) aus feuerfestem Werkstoff untergebracht wird, bei der die Innenfläche (4) des Hohlraumes (3) dem Preßkörper (2) kongruent ist, und daß die Länge des Hohlraumes (3) die des Preßkörpers so viel übersteigt, daß sich der Preßkörper beim Schwinden während des Erhitzens in einen immer engeren Teil des Hohlraumes (3) der Sinterform (1) verschiebt und dabei in ständigem Kontakt mit der Innenfläche des Hohlraumes (3) der Sinterform (1) bleibt.1. Sintering process for metal or metal-ceramic compacts that have at least one inclined surface have, in particular for end pieces of tools, characterized in that the pressed body (2) in a sintered mold (1) is housed from refractory material, in which the inner surface (4) of the cavity (3) the Press body (2) is congruent, and that the length of the cavity (3) that of the press body so much exceeds that the compact when shrinking during heating in one always the narrower part of the cavity (3) of the sintering mold (1) moves while in constant contact with the inner surface of the cavity (3) of the sintering mold (1) remains. 2. Sinterform zur Durchführung des Verfahrens nach Anspruch 1, dadurch gekennzeichnet, daß sie eine große Anzahl senkrecht angeordneter Hohlräume (3) zur Unterbringung von Preßkörpern (2) aufweist.2. Sinter mold for performing the method according to claim 1, characterized in that they have a large number of vertically arranged cavities (3) for accommodating pressed bodies (2).
