Abstract

The invention relates to a mixing and kneading machine (100) in which a worm shaft (12) is moved in a rotational manner and in a translational manner back and forth in a housing (10), wherein receiving areas for kneading elements (12) are distributed in a non-uniform manner. It is thus possible to populate the receiving areas with a varying number of kneading elements, thus allowing a quick retrofit. In one embodiment, the number of kneading elements varies even over the direction of extension of the mixing and kneading machine (100).

Abstract

The invention relates to a method (21) for producing a self-lubricating composite material, wherein a powdery primary metal material is mixed with a likewise powdery secondary material, and the mixture (3) is subjected to a hot-isostatic pressing process (28). In order to do so, the mixture of the primary material and secondary material is filled into a shaping mold, and the mold is evacuated, whereupon the actual hot-isostatic pressing process is carried out. This makes it possible to obtain a substantially compact desired material.

Abstract

What is proposed is a mixing and kneading machine (1) which is suitable, in particular, for continuously conditioning metals such as aluminium or magnesium for a subsequent die-casting operation. To this end, the mixing and kneading machine (1) has a worm shaft (3) which rotates and at the same time moves in translation in the axial direction in a housing (2). The temperature of both the housing (2) and the worm shaft (3) is controlled by means of a flowing gas in such a manner that the conditioned metal assumes a thixotropic state when it leaves the mixing and kneading machine (1).
