Coperion Twin Screw Compounder featuring a specific torque of 13.6 Nm/cm³
The STS Mc PLUS twin screw extruder features an increased specific torque of 13.6 Nm/cm³. This advancement allows the compounder to deliver enhanced product quality while increasing throughput by up to 20% across all applications compared to earlier STS models.
Key to this performance boost, alongside process-related modifications, is the optimization of the drive’s key components. The STS Mc PLUS extruder features a high-power motor and a gearbox specifically designed to handle high torque. Proven high-performance materials are used for the screw shafts to ensure effective torque transmission from the gearbox to the screw elements. The higher fill level in the process section is crucial to the improved compound quality achieved by the STS Mc PLUS, as it reduces both shear stress and melt temperature while enhancing mixing behavior. This results in an exceptionally gentle product handling at high throughputs.
