ZSK Mc¹⁸ Twin Screw Extruder | Coperion

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.
