Abstract (en)

[origin: WO2007031183A1] The invention relates to a method for producing an article comprising at least one autonomous part which is positioned such that it can move in relation to a fixing part. To this end, a die is first provided which has a cavity for each of the parts to be moulded, and these cavities are each filled with a curable or solidifying moulding composition which contains a pulverulent sintering material and a binder. After the moulding composition has been left to solidify, the part to be moulded respectively forms in each cavity and is then demoulded from said cavity. The demoulded parts are then inserted into a fixing part, as a result of which the article is formed, and this article is then subjected to a heat treatment in such a way that the at least one part can be moved in relation to the fixing part. In order to produce an article comprising at least two autonomous parts which are connected such that they can move in relation to one another and are positioned in relation to one another in a fixing part, a die is provided which also has a separating plane which separates the die into two die halves, and in which die the cavities for the parts are arranged such that they are separated from one another, in each case alternately, in one of the two die halves.
