EXTRUSION TECHNOLOGY - Leistritz

EXTRUSION TECHNOLOGYE xtruders and EXTRUSION lines23 LeistritzExtrusion TechnologyEXTRUSION TECHNOLOGYWith experience and passion Business unitWhen screw pumps for pumping viscous masses were further de-veloped at Leistritz nearly 80 years ago, it was barely imaginable that the present high-performance extruders would be the result. At the headquarters in Nuremberg/Germany, we conceive, design and produce individually laid out, co-rotating twin screw extruders and turn-key EXTRUSION lines for the plastics and pharmaceutical industry. This, in combination with sophisticated process TECHNOLOGY know-how, guarantees the high quality of our extruder lines. The heart of our ZSE MAXX extruders the screws and barrels are produced in the German Leistritz plants. The basis for this is the implementation of modern technologies, but particularly the nearly 200 employees worldwide a dedicated team that stands behind the branches in the USA, China and Singapore, sales offices in Italy and France and agents in all key markets, we have a global presence.

high free volume of the ZSE MAXX twin screw extruder (OD/ID = 1.66) means that there is enough space in the process chamber to ensure a good dispersion and high throughput. The additive feed often poses a challenge in process-ing: if additives with a low melting point are added, they could already melt in the side stuffer. This would lead to

TWIN SCREW EXTRUSION Twin screw extrusion machines or, twin screw extruders, are the simplest example of multi-screw machines (Figure 2.). The two screws may rotate in the same direction (co-rotation) or they may rotate in opposite directions (counter or, contra-rotation). The flights of the screws may intermesh or they may not intermesh.

Single screw versions are most common but twin or triple screw extruders may be used for comp lex products such as cable sheathing where they may be several layers of compound (co-extrusion). Screw extruders can be either hot fed, with warmed pre-mixed rubber, or cold fed.

Extruders may be classified by three figures, for example, 1-60-24. The first number states how many screws the machine has, the second number speci-fies the screw diameter in millimeters (mm) and, the third number specifies the effective screw length as a multiple of the screw diameter.
