Coperion Nanjing opens new plant
New manufacturing site meets high quality standards
Coperion (Nanjing) Machinery Ltd. Co., Nanjing, PR China, recently opened a new facility in the Nanjing Jiangning District. Coperion President Kimberly K. Ryan inaugurated the new plant in Nanjing Jiangning District in a formal and festive ceremony in the presence of Government officials of Nanjing Jiangning Economic & Technology Development Zone, representatives of Chinese plastics & machinery associations, media representatives, 150 customers and suppliers, employees and the entire Coperion Executive Team.
The plant opening marked the completion of the new construction and the relocation from the old plant to the new one. The move was necessary as the old site in Nanjing Jiangning District was rezoned by Nanjing Jiangning Government for future R&D and commercial development. With the support of the Government of Jiangning Economic & Technology Development Zone, Coperion was able to find a new plant for manufacturing and production purposes nearby. Construction work started in May 2014 and was finished in June 2015.
With a footprint of more than 15,000 sq. m the new production will continue to focus on manufacturing the STS and CTE twin screw extruder series. In order to serve Coperion’s manufacturing needs, the new building is designed with the following features: the most advanced machinery production technology with engineering and manufacturing know-how from Coperion Stuttgart, Germany and an optimized, tailor-made workshop layout for highly efficient production.
“We have moved to this new location in Nanjing in response to the importance of the markets in the Chinese and Asian regions” explained Ms. Ryan during her opening speech. She also mentioned Coperion’s 15-year history in China and talked about how Coperion Nanjing has grown from just a few employees in 1997 to almost 400 today.
“Coperion’s new Nanjing manufacturing plant is another step forward for Coperion and reflects the importance of Coperion Nanjing to our business” says Ms. Ryan. “We see it as an investment in the future and a clear commitment to our customers. Coperion Nanjing will continue to play an important role in our network, not only as an extruder manufacturing site but also from a customer service point-of-view.”
Joanne Shen, Coperion Nanjing’s Managing Director adds: “As Coperion Nanjing becomes more and more important as Coperion’s Asian hub, this new manufacturing plant supports our efforts to offer our customers best-in-class products and services. Our new test lab, upgraded with a high-end extruder from Coperion’s sophisticated ZSK Mc18 series and a wide variety of other equipment, displays Coperion’s flexibility and commitment to our Nanjing plant and underscores high expectations for future development.”

Complete installations for the production of long fiber reinforced thermoplastics
Coperion offers technology for long fiber compounds
Coperion is expanding its offering in the area of long fiber technology for the European and Asian regions. In cooperation with ProTec Polymer Processing GmbH in Bensheim, Coperion now offers complete installations for the production of long fiber reinforced thermoplastics (LFTs), meeting the growing need for LFT pellets. Components made of long fiber-reinforced plastics possess outstanding rigidity with low weight and increased impact resistance. Compared to short-fiber reinforced thermoplastics they also demonstrate improved mechanical and thermic material properties. With this improved quality, long fiber reinforced thermoplastics are well suited for higher stress und demanding areas of use.
Pultrusion for LFT pellet production
The production of long fiber reinforced thermoplastics takes place within the pultrusion process. Here glass, carbon, metal or natural fibers are mixed into a polymer matrix. Through the pultrusion process, the individual fibers of the strands are impregnated. A homogenous bond of carrier polymer and individual fiber results. Melting of the polymers and mixing of additives takes place within the extruder. Coperion uses the ZSK Mc18 twin screw extruder or the STS Mc11. The ZSK Mc18 series is used in particular for products with a high torque demand, such as Engineering Plastics or high-temperature applications; the STS Mc11 series is used for standard plastics such as polypropylene and polyethylene. Coperion K-Tron equipment is used for feeding, as it is particularly suited for raw materials in powder form, such as polymer powder, additive powder, or filler materials such as talc and chalk. Following impregnation, the fiber-polymer strands are cooled in a water bath and subsequently pelletized to rod shaped pellets. Coperion Pelletizing Technology GmbH’s pelletizer is equipped with a special chopping rotor for this task. The final pellet length is usually between 5 and 12 mm. Whereas in the past, primarily polypropylene was used as the base polymer, there is now a clear trend toward other polymers such as PA, PEEK or PLA, and others can be used as well according to need. Line speeds are up to 50 meters per minute, depending upon the used polymer.
Collaboration offers many advantages
The collaboration between Coperion and ProTec Polymer Processing offers numerous advantages. The complete line is offered with optimized components to enable the highest quality LFT pellet manufacturing. Among these, along with the ZSK Mc18 or STS Mc11 twin screw extruder series, is a specially designed impregnation die head, developed by ProTec, which cannot clog with filler material. Moreover, roving unwinding with rotating coils, as well as roving pre-warming with individual fiber spreading, enable the best possible fiber impregnation. The complete installation offers one further advantage: different polymers in combination with special additives can be used in the same production line. Support and development of customer-specific formulations can take place in ProTec’s Testing Center in Bensheim. This production of product samples allows to validate components manufactured with LFT pellets. Using twin screw technology and the special impregnation die head, it is also possible to use additional fillers and even regrind material. As a result, the customer receives a fully automated production line, set and optimized to the customer’s formulation.
The automotive industry is one typical area of use for LFT; however, this technology offers advantages for further application fields in which products are exposed to higher demands and stresses, and would thus benefit from higher quality. At this time, Coperion and ProTec are working on their first joint client project in Europe.
