>> Quality that you can expect. The standard STS advanced twin screw compounder stands out with its high compounding performance – at low investment costs.
STS advanced – the perfect symbiosis of maximum economy and product quality
- STS advanced compounder
Produced at the Coperion site in Nanjing, China, the STS advanced compounder rightly carries the predicate "Engineered in Germany". Because our high quality standards apply worldwide. The STS advanced compounder incorporates the entire Coperion process know-how and the advantages of our international network. Our goal with the STS advanced: to offer the market a twin screw compounder for standard applications at an attractive price-performance ratio. With this in mind we developed the series at the Stuttgart site – formerly Werner & Pfleiderer – according to German design and quality management guidelines. Production takes place in Nanjing, China under compliance with the CE directives. The result: an efficient compounding system with low investment costs which ensures our customers a fast return on investment.
The modular structure of the screw barrels and elements allows process lengths of 24 to 64 D. The STS advanced compounder therefore covers the majority of common standard applications in processing technology. With a total of five different sizes, throughput rates of up to 3,300 kg/h can be achieved depending on the process task.
The advantages of the STS advanced twin-screw compounder
| Screw speeds of 600 min-1 or 800 min-1 depending on the machine version |
| Two very user and maintenance friendly machine control concepts - BasicMaster (contactor control) and TouchMaster (PLC control) |
| German-made high-performance gear with high-tech safety clutch for reliable transmission of the high torque through the spline screw shafts to the screw elements. |
| 4D single barrel with precision single zone tempering |
| High-performance brass heater shells and water injection cooling for optimum process conditions at each heating zone |
| Self-cleaning, co-rotating screw shafts with a tight sealing profile for fast, simple product change |
