STS Mc11 and the CTE PLUS - two new twin screw extruder series
Successful introduction of the latest twin screw extruder STS Mc11 and CTE PLUS
At this year’s Chinaplas 2015 we successfully introduced two new twin screw extruder series: The twin screw extruder STS 65 Mc11 and the CTE 50 PLUS.
Twin screw extruder STS Mc11
With its specific torque of 11.3 Nm/cm3 the STS Mc11 sets new standards: it features throughput rates of up to 27% higher than the preceding model and for the first time benefits from Coperion’s industry-proven ZSK MEGAcompounder patented design. It incorporates our full process and quality know-how.
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 Mc11 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.

Twin screw extruder CTE PLUS
With the CTE 50 PLUS Coperion Nanjing, China, launches a twin screw extruder at a very attractive price-performance-ratio. Its precise manufacturing ensures the economical processing of a wide range of applications at high product quality.
To improve reliability and to ensure longer life time Coperion Stuttgart, Germany, has engineered new gearboxes for the CTE PLUS that can bear a specific torque of 7.2 Nm/cm3 and are exchangeable with old generation CTE’s gearboxes. It offers a new terminal box that meets highest safety standards and is supplied on a new base frame. Before delivery each CTE PLUS extrusion system is subjected to a Factory Acceptance Test (FAT) at the Coperion Nanjing site to ensure high quality standards.

New bagging machine IBP 250/500 for testing
New test machine available at Coperion K-Tron in USA
Recently, a new test machine arrived at the test laboratory at Coperion K-Tron Pitman, New Jersey, USA, after it was displayed at the NPE Show 2015 (Orlando, FL, USA): The Coperion bagging and palletizing machine IBP 250/500.
The machine was originally produced at Coperion Italy and now will be used for a test machine in Pitman.
The machine is now ready for testings with full-scale testing capabilities. Materials expected to be tested in Pitman are pellets, fertilizer, salt or any free flowing material (> 100 microns).
The first trials have already passed!
The advantages at a glance:
- All packaging functions from weighing to palletizing in one single unit
- Small footprint
- Integrated bag flattener
- Simple design for high availability and good accessibility for easy maintenance
- Modular design facilitates future capacity upgrade
- Operation, changes of setup and maintenance are easy and intuitive by touch screen
Even better performance: Coperion's Kombiplast KP revised
New version of Coperion's Kombiplast KP already in operation
The Kombiplast KP compounding system from Coperion, Stuttgart, Germany, is from now on available in a revised version with considerably improved performance. More compact and more energy-efficient than its predecessor, this new model achieves even better product quality at an even higher throughput rate.
The Kombiplast features gentle compounding of heat and shear sensitive plastics.
These advantages range from the short and definable residence time profile of the material in the extruder process section to the rapid and easy cleaning of the system and the ready adaptation of the system to new tasks. Typical areas of application are the stable, energy-efficient compounding of flexible and rigid PVC, the production of special-purpose compounds such as halogen-free, self-extinguishing formulations for cables (HFFR) or elastomer-based compounds for the production of low, medium and high voltage cables.
In its search for a compounding system for PVC, the Italian fittings manufacturer Formatura Iniezione Polimeri S.p.A. (FIP) was very impressed by the performance of the Kombiplast. The first unit of the new, improved series – a KP 62 Mv PLUS/200 – has already been put into operation at the FIP facility in Casella, Italy. Featuring a screw diameter of 62 mm, the extrusion system at FIP is being used for the compounding of tailor-made rigid PVC compounds at a throughput rate of up to 1,600 kg/hour. The PVC compound is then injection-molded into valves for pipe system fittings.

Bulk Solids Innovation Center in Salina, USA
Grand Opening on June 24, 2015
The new Kansas State University Bulk Solids Innovation Center in Salina, Kansas, has officially opened its doors: On June 24, 2015 the Grand Opening took place in the presence of more than 130 official guests.
The Bulk Solids Innovation Center (two-story 13,000 ft² / 1,208 m² building) has been built adjacent to the Coperion K-Tron Salina office. The Kansas State University, several government agencies and private companies, as Coperion K-Tron, will use it to study and develop the understanding of bulk solids materials handling, in turn enhancing the businesses that use these materials or manufacture the systems that convey, store and dispense them. This university-level research center is the only one of its kind in North America and will serve as the new home of the Materials Handling Test Lab for Coperion and Coperion K-Tron in the Americas.
Kansas State University Bulk Solids Innovation Center at a glance:
- Research areas - six laboratories for university and industry sponsored research
- Training/education center conference and lecture rooms
- Material properties test lab - bulk solid and particle properties will be evaluated and modeled in a test bench environment
- Full scale bulk solids test bay - full scale systems to include: vacuum and pressure dilute phase, vacuum sequencing, vacuum and pressure vessel dense phase, rotary valve dense phase, batch weighing, silo zone blender, gravity flow, air filtration, feeding, mixing and silo storage
- Research fellows, doctoral candidates and students
- Continuing education and university level courses about bulk solids
- Adjacent to Coperion K-Tron Salina
Salina, Kansas has a tremendous history of bulk solids handling dating back as far as 1942.
The timeline demonstrates Coperion K-Tron's history and contribution to bulk solids handling. The company originally started in 1950 as Salina Manufacturing, then in 1978 become Premier Pneumatics, in 2006 was purchased by K-Tron and today, Coperion K-Tron.
