STS Mc¹¹ Extruders

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.

The STS Mc¹¹ compounder 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.

KEY BENEFITS OF THE STS Mc¹¹ EXTRUDER SERIES

STS side feeder: new design with swivel arm

• Swivel arm allows easy docking and optimal alignment to adjacent barrels
• Engineered by Coperion Stuttgart, Germany, equipped with European gearbox, final assembly at Coperion Nanjing, China
• High torque, deep cut screw channels and D_o/D^_i ~ 2 to achieve high throughput rates
• High pressure built up to 30 bar
• High-low speed motor or frequency control motor
• High manufacturing precision, only 2 mm clearance between side feeder screws and twin screws of STS Mc¹¹

Feed hopper in quick-change design

The feed hopper is simply clamped to the inlet barrel and can be quickly removed by loosening the bolts. The quick-release insert which protects the barrel wall from contamination can then be changed very easily.

Quick cleaning die head

• Simple, quick opening by loosening a few bolts
• User-friendly assembly due to pivoting arm
• Insertion of screens possible by using breaker plates
• Optimized flow geometry with minimal dead space for safe strand discharge, even with highly filled products
