Plastindia 2023: Coperion to focus on highly efficient manufacturing and compounding

Source:Adsale Plastics Network Date :2023-01-05 Editor :JK

At Plastindia 2023, to be held from 1 to 5 Feb in New Delhi, Coperion will present innovative solutions and new developments at its booth to help increase the efficiency of polyolefin manufacturing and engineering plastics compounding.


Together with machine manufacturer Herbold Meckesheim, which recently merged with Coperion, various processes and plant solutions for reclaiming plastics of all kinds will be on display.


These complete systems for mechanical and chemical plastics recycling stand out for their high levels of automation, conscientious use of resources, and the extremely high product quality they achieve.


Innovative developments in polyolefin manufacturing


One new Coperion plant concept now allows the energy-efficient incorporation of recyclate into polyolefin production. Conventional polyolefin manufacturing processes using recyclates require three steps: preparation of new material; mechanical recycling with filtration and pelletizing of the waste plastic; and mixing the two product streams.


Coperion's new process solution allows mechanically recycled and filtered melt to be added directly into the extruder where the new material is manufactured. Energy-intensive mixing and melting of the new material stream and PCR compounds are completely eliminated, significantly dropping investment and operating costs.


The especially low-leakage ZXQ 800 rotary valve is ideal for powder intake into the pneumatic conveying of high-output systems used in polyolefin manufacturing.

Another highlight of Coperion’s presence at Plastindia will be the ZXQ 800 rotary valve. Coperion developed this high performance, low gas leakage valve especially for powder intake into pneumatic conveying up to 3.5 bar. With its enormous capacity, it is optimally suited for high-throughput polyolefin plants.


Super-efficient compounding


Along with polyolefin equipment, the company will also be demonstrating versatile uses of its technologies and process expertise in various compounding tasks, from filling and reinforcing engineering plastics and masterbatch preparation to bioplastic manufacturing.


Compounding with Coperion’s ZSK and STS twin screw extruders, as well as material conveying and feeding, stand out for their very high degree of automation and efficiency. Thanks to its high specific torque of 18 Nm/cm3, the ZSK extruder achieves very high throughput rates with comparatively low energy consumption.


Bulk material handling is extremely gentle on product and raw material feeding is highly accurate. Product changes can be accomplished in no time, increasing overall equipment effectiveness (OEE).


Emblematic of its first-class technologies for compounding, Coperion’s ZRD 200 rotary valve for discharge and metering of powders as well as the WZK 100 two-way diverter valve will be on display.


Additionally, the T35/S60 Quick Change (QC) feeder with the 2415 pellet receiver will be available to view. The QC feeder is suited especially for applications requiring maximum flexibility in feeding and material changeover. It allows the feeder unit, including the screws, to be quickly and easily removed and installed.


The single screw feeding design handles free flowing powders, granules, pellets and other free flowing materials. The twin screw design is ideal for floodable powders and more difficult, sticky or hard-to-flow materials.


With the preconfigured ProRate PLUS feeder in size S, Coperion offers a robustly constructed, continuous gravimetric feeder at a very good price-to-performance ratio, perfect for economical, reliable feeding of free-flowing bulk materials.


Complete plastics recycling plants from a single source


Moreover, Coperion and Herbold Meckesheim realize entire plants for plastics recycling. From mechanical processing to bulk material handling as well as feeding and extrusion all the way to compounding and pelletizing, their systems cover the entire process chain for reclaiming plastics.


With complete systems from a single source, Coperion and Herbold Meckesheim are enhanceing plastics recycling.

They achieve solutions for mechanical recycling of post-industrial and post-consumer waste, chemical recycling, solvent-based recycling, and deodorization, tailored to the type of plastic being recycled.


Together, they will be showing a PET recycling plant simulation at Plastindia, demonstrating their expertise in numerous plastics recycling processes. Booth visitors can look directly into entire process steps and view the construction and functionality of key technologies.

Coperion added that its ultramodern Recycling Innovation Center demonstrates the importance of plastics recycling for Coperion. It is currently under construction right next to Coperion's existing Test Center for bulk material handling at the Niederbiegen/Weingarten, Germany, production facility.

In this new Test Center, dedicated specifically to recycling applications, Coperion will advance its industry-leading research and development in an environment where every major process stage can be tested under production conditions and put through their paces by customers prior to making an investment.
