High speed, high efficiency, and energy-saving have been the main theme of continuous improvement of international plastic extruder machinery in recent years. This article will briefly introduce the twin screw extruder manufacturers at home and abroad.
The Coperion Group is a global leader in plastic compounding and extrusion systems and bulk material conveying systems. Its four production bases (Coperion Werner & Pfleiderer-Germany, Coperion Waeschle-Germany, Coperion Kea-China, Coperion Hartmann-Germany) are currently collectively referred to as the "Coperion Group". It has accumulated more than 300 years of history. The Coperion Group has three R&D centers worldwide: Coperion headquarters in Germany, Coperion America, and Coperion China. 75% of the world's new compounding materials are successfully developed at Coperion's R&D center and put into mass production.
Founded in 1837 and headquartered in Munich, Germany, Kraussmaffei is the only company in the global market that integrates three major plastic processing equipment technologies: extrusion, injection molding, and reaction foam molding.
As a subsidiary of Kraussmaffei Kraussmaffei, founded in 1897, Krauss-Maffei Berstorff, headquartered in Hanover, Germany, represents the entire extrusion system. As the world's top compounding and granulating twin screw extruder manufacturer, it not only provides high-performance equipment but also customizes special processing solutions and systems for customers. Continuously carry out R&D and innovation in the plastic industry technology to lead the development of the industry.
As a well-known family business, Leistritz Group owns multiple companies worldwide in four fields: production technology, extrusion technology, pump technology, and turbine technology.
Germany in 1905-In a factory in Nuremberg, Paul Leistritz completed his first work: blades and profiles for steam turbines. A thousand miles begins with a single step. A small start at that time made the world-famous company today—the Leistritz Group with 2,000 employees composed of four major areas: turbine technology, pump technology, production technology, and extrusion technology companies.
German battenfeld extrusion technology company exhibited its new high-volume extruder BEX2-135V Plus for the first time in Düsseldorf. This twin-screw extruder can process PVC with a high output of 1,000kg/h, which brings opportunities to further increase the production capacity of window profile extrusion.
While maintaining the ideal plasticizing performance, the processed parts of the extruder have been further improved to improve energy efficiency. BEX2-135VPlus is also equipped with a T1max gearbox with a torque of 58,000Nm and a direct drive motor. It is precise because of these innovations that the output of this extruder has increased by 30% compared with the original successful model, reaching a maximum output of 1,000 kg/h.
In 1979, Japan's JSW's first TEX65 counter-rotating twin-screw experimental machine installed at the Hiroshima Works came out. After some internal commissioning, a full-scale test began in 1980. The machine can be used as a specific test for potential users, select the product model specifications, collect and analyze all the test data, in order to guide future continued tests. In this way, the twin-screw extruder has developed rapidly.
The new TEX twin-screw compounding extruder manufactured by Japan Steel has been sold for more than ten years, and users' requirements for the hardware and software of this model have become increasingly strict. In order to meet the requirements of users, the hardware and software of the twin screw extruder developed by Japan JSW has always been the leader.
Founded in 1875, Shibaura Machine is committed to working hard for the future of mankind and the earth, striving to become an enterprise group that can create rich value and contribute to the life and culture of all mankind. Shibaura Machine took the lead in manufacturing a fully meshed counter-rotating twin screw in 1955.
Chuangbo is committed to high-polymer compound modification, reactive extrusion, post-reaction treatment, continuous long-fiber impregnation and coating, mixing and forming one-step method, and carbon dioxide foam extruding represented by co-rotating twin screw extruders. Short processes, intelligent equipments and related technology are applied in product manufacturing as well as turnkey projects. In the field of high polymer compounding equipments, it is the eternal pursuit of Chuangbo to build a leading domestic and internationally renowned modern national brand. We have been awarded as a “High-Tech Enterprise” and a “Private Technology Enterprise in Jiangsu Province”.
Nowadays, the most powerful manufacturers in the world are developing in the direction of multi-function, large-scale and precision.
In terms of function, the twin-screw extruder is no longer limited to the molding and mixing of polymer materials, and its use has expanded to the fields of food, feed, explosives, building materials, packaging, pulp and ceramics. In addition, the "one-step direct extrusion process" that combines the mixing and pelletizing and extrusion molding processes into one is also very attractive. The realization of large-scale extrusion molding equipment can reduce production costs, especially for large-scale twin-screw pelletizing units, film blowing units, and pipe groups. In China, large-scale equipment has long relied on imports, and research on the localization of large-scale twin screw pelletizing units is currently underway. Precision can increase the gold content of products, such as multi-layer composite co-extruded films.
