ZSK Mc18 High-Performance Twin-Screw ExtruderIt is an outstanding product. With a torque of 18 Nm/cm³, it has gained a strong reputation in the market as the capacity champion for high-torque-demand products such as engineering plastics.

Compared to the previous ZSK Mc PLUS extruder model, the torque has increased by 30%, and the production capacity can be increased by up to 100%. Therefore, the ZSK Mc18 twin-screw extruder can ensure production with very high economic efficiency.

Coperion’s strength lies not only in the ability of its gearboxes to withstand extremely high specific torque, but also in its profound understanding of screw configuration–material fluid dynamics.

Whether it's handling tens of thousands of tons of petrochemical post-processing extruder units or high-difficulty blending of heterogeneous materials, Kebelon is the top choice for global multinational chemical giants.

As the all-round champion of global plastics machinery, KraussMaffei’s confidence in the compounding field comes from its deep integration of the classic German brand Berstorff’s technology. KraussMaffei’s core advantage lies in its “full-line turnkey capability.”

It not only provides a twin-screw extruder, but can also seamlessly integrate upstream automatic feeding, downstream pelletizing systems (water-ring, underwater, and air-cooled), as well as an intelligent centralized control system. In large chemical enterprises and high-volume PP and ABS compounding lines, KraussMaffei demonstrates strong compounding capabilities.

The equipment can be customized as required and expanded or upgraded at a later stage.

Relying on a complete extrusion technology system, KraussMaffei can integrate the extrusion main machine with supporting components such as feeding equipment, vacuum pumps, melt filters, pelletizing units, and extrusion dies into a unified system. The professional process capabilities of the entire production line are further complemented by the brand’s pioneering process control (ppC) system, which was specially developed for the extrusion industry.

If one were to seek the ultimate embodiment of “German precision engineering” in industry, it would undoubtedly be Leistritz.

Because it does not pursue scale blindly, but instead focuses on the high-value-added, technically demanding field of customized compounding, it is respectfully regarded within the industry as the "Porsche" of the twin-screw extrusion world.

ZSE MAXX Series (Image source: Leistritz official website)

The Leicester ZSE MAXX series twin-screw extruder combines high torque with the advantages of large volume.
