H. Potente et K. Kretschmer, Optimised in 60 seconds - Computer-aided design and optimisation of co-rotating twin-screw extruders, KUNSTST-P E, 91(9), 2001, pp. 76
The design of co-rotating twin-screw extruders is frequently based on exper
ience and time-consuming trial and error. Simulation of the process through
computer programs such as "Sigma" significantly shortens the time involved
and also lowers the costs.
