Preface The co-rotating twin-screw is used in many of today’s industries, particularly in polymer processing. However, the development of this type of machine goes back a long way.
The co-rotating twin-screw extruder is a versatile device for material preparation. The earliest generation extruder had mean residence time of 300 seconds During the course of the last 50 years, the residence time has been reduced to half its original value every ten years or so.
The co-rotating twin screw extruder ZSK, as seen before, is used in many applications with different materials and needs. All these applications are within the automotive industry and therefore the equipment has to achieve specific requirements set by the automotive sector.
