COPERION product ranges:

With Coperion you have the partner at your side who can offer you the best solution for all your compounding tasks. This begins with special applications on a laboratory scale and extends right through to industrial production plants.

ZSK series

The ZSK series combines the results of more than 50 years of process and processing competence. It is the high-end, high-tech heart of our systems with the maximum torque, speed and free volume.

STS series

The STS series features a high degree of standardization and is especially suitable for standardized process tasks. It combines the process technology expertise of Coperion in Germany with the serial production in China at an attractive price-performance ratio. Since the series is certified according to CE standards, it can also be used in Europe.

CTE & CKY series

The CTE and CKY series are developed and produced in China. They are specially adapted to the requirements of the Asian market and have no CE certification.
