ZSK Mc Twin Screw Extruder
ZSK Mc Twin Screw Extruder
Maximum torque for highest throughput
The ZSK Mc18 high performance twin screw extruder is a superlative product. With its torque of 18 Nm/cm3, it has made a name for itself on the market as a throughput champion for products with high torque requirement such as engineering plastics. The 30% increase in torque compared to the predecessor extruder model ZSK Mc PLUS leads to increases in throughput of up to 100%. Therefore the ZSK Mc18 twin screw extruder ensures production with maximum economic efficiency. The optimum price/performance ratio, the extremely energy-efficient operation, the wide range of applications, and the associated high level of flexibility of the machine are additional advantages.
With its Do/Di of 1.55, the ZSK Mc18 strikes just the right balance. It has proven itself in the processing of products with high torque requirements and enables reliable scale-up within the entire Mc18 twin screw extruder series. In addition, it is possible to scale-up and modernize the ZSK Mc PLUS series to the Mc18 series.

TYPICAL AREAS OF APPLICATION OF THE ZSK MC¹⁸ TWIN SCREW EXTRUDER
- Continuous processes with high energy consumption
- Processing of all previously torque-limited products such as polyamide with glass, PBT with glass, glass fiber-reinforced polypropylene
- Mixing and dispersing of pigments and additives
- Reinforcement with glass, carbon and other fiber materials
- Degassing of volatile components
- Filling with talcum, calcium carbonate, sawdust or other fillers
- Alloying
- Reactive extrusion
- Chemical reactions such as polymerization, polycondensation and polyaddition
- Direct extrusion
The gearbox lantern of Coperion ZSK twin screw extruders can be optionally equipped with an electronically secured maintenance opening. As soon as the screw shafts come to a complete stop, service personnel can open the gearbox lantern without tools, guaranteeing secure, easier access to the screw shaft coupling.
This feature, which is available from a size of ZSK 32, significantly simplifies screw changes and mainte-nance, which again reduces the machine’s downtimes, thus contributing to greater efficiency of the system.
