(2) Verbreitung des modularen Designs, Anpassung an flexibles Umschalten mehrerer Prozesse

Modular design has become the standard configuration of China’s twin-screw extruders, which is mainly reflected in the building block screw combination and detachable barrel structure. By replacing screw elements with different functions (conveying section, mixing section, shearing section, venting section), precise adaptation to different material characteristics (viscosity, melting point, filling rate) and process requirements (dispersion mixing, reactive extrusion, devolatilization and purification) can be realized, greatly improving equipment versatility. Nanjing KYA’s HK series third-generation twin-screw extruders are typical representatives of modular design. Their independently developed screw elements can be flexibly combined according to different application scenarios such as special fibers, hollow fiber membranes, rubber desulfurization, and lithium battery materials. Compared with the previous generation models, the production capacity is increased by 30-60%, and the adaptability covers the whole field from conventional polymer compounding to high-end special material processing. The KTE series models of Nanjing Kerke Extrusion Equipment Co., Ltd. adopt a full modular design concept. In addition to the conventional building block screw combination, their barrels, feeding devices, venting systems, etc. all adopt modular structures, which can quickly adjust the configuration according to the specific process needs of customers, adapting to the processing of various materials from masterbatches, modified plastics to degradable plastics. Moreover, the convenience of module replacement is further improved, and the production change time is shortened by 10-20% compared with the industry average.

Darüber hinaus verkürzt das modulare Design auch die Inbetriebnahme- and Produktionsumstellungszyklen der Ausrüstung erheblich. Am Beispiel der KTE-Serienmodelle der Nanjing Kerke Extrusion Equipment Co., Ltd. lässt sich die Baukasten-Schneckenkombination innerhalb von 2–4 Stunden vollständig austauschen, was über 50 % effizienter ist als bei traditionellen Modellen and sich besonders für Kleinserien- and Mehrvariantenproduktionsbedürfnisse eignet.
