Eighty years ago, an exciting event took place in the plastics machinery industry. The first twin-screw extruder capable of producing polymers and processing was born! Now 80 years later, twin-screw extrusion The machine has been widely used in various fields such as PVC pipe, food industry, pharmaceutical industry, etc. After years of accumulated experience and research, the twin-screw extruder has been continuously innovating on the road to its development, bringing vision from time to time. Dual experience with technology.
As a representative of high-end twin-screw extruders, Coperion has considerable research in the development of twin-screw extruders. The company's 58-mm ZSK 58 Mc18 twin-screw extruder is designed to meet the high quality of the Chinese market. Newly built equipment for the growing demand for products. With regard to the ZSK 58 Mc18 extruder, Coperion adopted Germany's high-precision manufacturing equipment and quality measuring equipment to strictly monitor production and assembly processes. Compared to the previous double Screw Extruder, This extruder has the advantages of high processing efficiency, good quality of finished products and safer processing.
The German twin-screw extruder Lesteritz, in the world of co-rotating twin-screw extruder, has always been the leader in technology and market. The company exhibited ZSE CC series twin-screw at this year's Chinaplas exhibition. Extruder follows the concept of "German Engineering Design - Meeting China's Purchasing and Assembly with High Standards", adopting German imported key components and German design standards to assemble in Taicang, which not only guarantees high-quality extrusion standards, but also satisfies the Chinese market. The special needs of customers.
In addition, KraussMaffei's new generation of ZE-CN series twin-screw extruders are equipped with a more powerful transmission system and screw threads and mandrels made of special materials to increase the torque density to 12.0 Nm. /cm3, which in turn increases production efficiency. At the same time, the expanded 4D and 6D barrel modules can be used to facilitate the precise adjustment of the processing unit according to customer requirements. C-Clamp's clamping flange system simplifies the installation and disassembly of the barrel. Shorten the preparation time when changing the barrel.
Twin-screw extruders are not only constantly updated in terms of equipment, but also in process technology innovation.
For example, multi-layer co-extrusion technology. By using this technology, an extruded composite film structure system designed by a twin-screw extruder can be integrated into functions, technologies, costs, environmental protection, safety, and secondary processing. The ideal realm, so as to realize the possibility of maximizing the number of composite layers. Another example is the melt gear pump technology. In order to better meet the needs of product applications, at the same time to reduce the cost of materials and improve the quality of products. Polymer melt gears Pump is one of the important means. Today, this technology has been widely used in chemical fiber, film, profile, pipe, sheet, cable, composite extrusion, granulation and other production lines.
The twin-screw extruder has experienced revolutions and innovations from time to time in the 80 years since its inception in 1938. Currently, in the polymer blending industry, twin-screw extruders have become a more representative process. Equipment. Through the development history of twin-screw extruders, it is not difficult for us to see that behind every change, the twin-screw extruder market is constantly reflecting the needs of the development of the daily update. With the continuous promotion of new market demand, twin-screw Extruder technology development can be continuously improved.
