Extrusion process engineering approach

There is one piece of equipment that approaches the process engineer s dream of a machine that takes in raw materials at one end and finished product emerges from the far end. That machine is the high pressure extruder. Unfortunately, while high pressure extrusion can make crisp-bread it has a limited application in the bakery sector. 

In the concrete case of rubber profile extrusion, several additional complications arise that result in very complex production processes. Common approaches for automatic control, e.g., from chemical engineering, do not suffice in this setting due to the complex and non-deterministic properties of these processes, which are mainly caused by the following issues.
