Next generation Coperion STS extruders to debut at Chinaplas 2015

The next generation of Coperion’s STS twin screw extruders is making its world public debut at Chinaplas 2015. The new STS Mc11 series features an increase in torque from 10 to 11.3 Nm/cm³ and for the first time is part of Coperion’s industry-proven ZSK MEGAcompounder method patent.

When it comes to compounding with high energy input, the new STS Mc11 series provides increased throughput by up to 27 % as well as decreased melt temperature due to higher screw filling, thus improving the quality of the resulting compound.  

The new STS Mc11 series is exclusively equipped with high quality European gearboxes. Screw speed has been increased from 800 to 900 rpm. To improve cleaning and quick change for masterbatch applications, the STS Mc11 is equipped with new hoppers with inserts and a redesigned die head. The screw shaft coupling is similar to the time-tested design of the ZSK Mc18 series.

During the development process of the new STS Mc11 series, Coperion Nanjing, China - the production site of the STS series - has undertaken comprehensive moves to improve its quality standards. Coperion Nanjing is now using state-of-the-art German machining centers and time-tested Coperion quality production standards have been implemented. The entire production and assembly process is closely controlled by Quality Check Points and Factory Acceptance Tests (FAT) using high-precision, high-level German production and quality measuring machinery and equipment.

Coperion presents the new STS 65 Mc11 twin screw extruder together with a feeder from Coperion K-Tron at Chinaplas 2015 booth no. 5.1K11 in hall 5.1.
