STS Mc Compounder

Compounders for considerable increases in throughput - With its specific torque of 11.3 Nm/cm3 STS Mc11 compounders sets new standards: it features up to 27% higher throughput rates than the preceding model, while the higher degree of screw fill results in a decrease of melt temperature, thus improving compound quality. It incorporates the full process and quality know-how of Coperion.

The STS Mc11 series is exclusively equipped with European, Coperion branded gearboxes. Maximum screw speed has been increased from 800 to 900 rpm. To improve cleaning and facilitate quick changeovers for masterbatch applications, the STS twin screw extruder also features new hoppers with inserts and a redesigned die head. The screw shaft coupling is similar to the one long proven in the ZSK Mc18 series. The new, optimized base frame withstands torsion under maximum stress.
