The extrusion process is used for the production of plastic tubes, profiles, platens, film, etc. The molding compound granules are continuously fed into a screw conveyor, which rotates inside a heated metal cylinder. The resulting frictional heat together with the heat introduced from outside, melts the plastic granulate, the rotating screw homogenizes the developing melt and at the same time transports it through the outlet nozzle, which already contains the contours of the product to be extruded. This way, the plastic melt assumes, for example, the shape of a window profile, a narrow cannula or a pipe. Complex calibration and the cooling process follow.

In most cases, a take-off unit forms the end of such an extrusion line, which pulls, or extrudes, the product from the extruder. With the combination of several extruders to one co-extruder it is possible to produce very complex multi-layer products, e.g. fuel lines for the automotive industry, consisting of different types of plastic in just one cycle. For safety reasons, the walls of fuel lines must be made up of at least four layers.

All process parameters of the overall system are detected by the system control and visualized by the central control unit. The available system solutions of different dimensions cover virtually all features of the versatile extrusion process. Adaptations are usually made by means of simple on-site configuration and no longer require time-consuming software modifications.
