Reitruder - co-rotating twin-screw extruders
The Reitruder has a modular design. The barrel and screws can therefore be assembled in any combination to construct a plasticising unit with raw material infeed and venting. The two parallel, co-rotating screws closely intermesh and are self-cleaning. They are divided into segments. This enables the screw geometry to be adapted to the respective application. The order in which kneading and mixing elements are arranged can be freely selected, depending on the formulation. The screw segments and screw shaft are form-fit. Therefore individual segments can easily be replaced and thus ideally be adapted to the respective material.

In comparison with other procedures, the advantages of direct extrusion by means of a Reitruder mainly lie in the profitability and the quality standards of semi-finished products and finished products. The reason is obvious: In the Reitruder, the plastic is processed from source material to final product in one production process, without intermediate solidifying and remelting. Compared with pre-mixed compounds, direct extrusion thus saves you up to 30 % in raw material costs and simultaneously provides improved product properties.
