ZSK Mc¹⁸ Twin Screw Extruders

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.
