  text: A large proportion of plastics today is compounded, which means the process
    from refining a raw material to the processable material. For this process compounding
    extruders are used which mostly involve tightly intermeshing, co-rotating twin
    screw extruders. These extruders consist of two closely spaced screws which rotate
    in the same direction and convey the raw material to the screw tip. These screws
    are surrounded by several barrel modules which heat or cool the material. As the
    whole design of the machine is modularly arranged the process behavior of a twin
    screw extruder depends for the main part on the arrangement of the screw and the
    barrel elements. Until today this arrangement and process optimization is conducted
    by experienced engineers and with the help of trial-and-error methods. Furthermore,
    theoretical models are used with which the behavior of the extruder is estimated.
    As these models are mostly very complex they are only made available with the
    realization in different software projects. One of the tools is called SIGMA.
    Within this paper SIGMA is introduced as a software to optimize a twin screw extruder.
    SIGMA supports the engineer already in the early stages of the extruder arrangement.
