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 D_o/D_i 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

Optimized Side Degassing ZS-EG easy and Side Feeder ZS-B easy

The new easy design of the ZS-B and ZS-EG permits much faster dismantling from the ZSK extruder process section and the twin screws can be changed very simple. Time for cleaning e.g. for recipe changes decreases obviously.

Electronically Secured Maintenance Opening at Gearbox Lantern

Coperion Extruders - Electronically Secured Maintenance Lock at Gearbox Lantern

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 maintenance, which again reduces the machine’s downtimes, thus contributing to greater efficiency of the system.
