Eighty years ago, the plastics machinery industry had an exciting event – the first twin-screw extruder that could make polymers and process them was born! Now eighty years have passed, twin-screw extrusion The machine has been widely used in many fields such as PVC pipe, food industry, and pharmaceutical industry. After years of experience accumulation and research, the twin-screw extruder has been continuously updated on the road of its development, bringing the experience of vision and technology again and again.

As a representative of high-end twin-screw extruders, Coperion has researched the development of twin-screw extruders. The company's 58mm ZSK 58 Mc18 twin-screw extruder is a new device designed to meet the growing demand for high-quality products in the Chinese market. With regard to this ZSK 58 Mc18 extruder, Coperion uses German high-precision manufacturing equipment and quality measuring equipment to strictly monitor the production and assembly processes. Compared with the previous twin-screw extruder, the extruder has the advantages of high processing efficiency, good quality of processed products and safer processing.


Germany's Lesterez twin-screw extruder has been a leader in technology and market in the world of co-rotating twin-screw extruders。 The ZSE CC series twin-screw extruder exhibited by the company at the Chinaplas this year follows the concept of “German engineering design – meeting the high standards of China's procurement and assembly”, adopting German imported key components and German design standards in Taicang。 Assembly not only guarantees high quality extrusion standards, but also meets the special needs of customers in the Chinese market。


In addition, KraussMaffei's new generation ZE-CN series twin-screw extruders are equipped with more powerful transmission systems and threaded components 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 extended 4D and 6D barrel modules make it easy to precisely adjust the machining unit according to customer requirements。 The C-Clamp's clamping flange system simplifies the installation and removal of the barrel, reducing the time required to replace the barrel。


The twin-screw extruder is not only constantly updated in terms of equipment, but also innovating in processing technology。


For example, multi-layer coextrusion technology. By using this technology, the extruded composite film structural system designed by the twin-screw extruder can achieve the ideal boundary of function, technology, cost, environmental protection, safety and secondary processing, thereby realizing the number of composite layers. Maximize the possibilities. Another example is the melt gear pump technology. In order to better meet the needs of product applications, at the same time achieve the purpose of reducing material costs and improving product quality. Polymer melt gear pumps are one of the important tools. Today, this technology has been widely used in chemical fiber, film, profile, pipe, sheet, cable, composite extrusion, granulation and other production lines.


Since the birth of the twin-screw extruder in 1938, it has undergone repeated changes and innovations. At present, in the polymer blending modification industry, twin-screw extruders have become a more representative processing equipment. Through the history of the development of twin-screw extruders, it is not difficult to see that behind every change, the development needs of the twin-screw extruder market are constantly changing. With the continuous promotion of new market demand, the technical development of twin-screw extruders has been continuously improved and upgraded.
