>> STS Mc11 – the next generation of Coperion’s STS twin screw extruders. Featuring a specific torque of 11.3 Nm/cm3.
STS Mc11 – advancing into a new dimension of processing technology.
With its specific torque of 11.3 Nm/cm3, the STS Mc11 boasts a considerable increase in throughput with improved product quality. The STS Mc11 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 new 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 changovers for masterbatch applications, the STS 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. The STS Mc11 series covers most standard applications in process technology. It offers high productivity at an attractive price-performance ratio. Production of the STS Mc11 is in Nanjing, China, in compliance with CE directives. The result: A high-performance compounding system with low investment costs which ensures a fast return on investment. The modular design of the process section allows maximum flexibility in production at process lengths of 24 to 68 D.
