(2) モジュール設計の普及、複数のプロセスの柔軟な切り替えに対応
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.
さらに、モジュール式設計により、設備の試運転と生産変更サイクルも大幅に短縮されます。南京ケルケ押出設備有限公司のKTEシリーズモデルを例にとると、ビルディングブロックのねじ組み合わせは2～4時間以内に完全に交換でき、従来のモデルよりも50％以上効率が高く、小ロットおよび多品種生産のニーズに特に適しています。
(3) 省エネルギー技術の革新、グリーン製造の概念の実践
Driven by the dual-carbon policy, energy conservation and consumption reduction have become the core direction of China’s equipment research and development. Through the optimization of transmission systems, the application of heat recovery technology and lightweight design, the unit energy consumption of China’s twin-screw extruders has decreased by an average of 18.7% compared with 2018. Among them, the comprehensive power saving rate of models adopting the permanent magnet synchronous motor + frequency conversion drive scheme can reach more than 22%, which can significantly reduce operating costs in large-scale production scenarios. Nanjing KYA’s HK series models reduce energy consumption by 15-25% compared with the industry average by optimizing screw configuration and transmission efficiency, making them energy-saving benchmark products in the modified plastic industry. Nanjing Kerke Extrusion Equipment Co., Ltd. has also achieved remarkable results in energy-saving technology. Its high-end KTE series models are all equipped with permanent magnet synchronous motors and high-efficiency frequency conversion systems as standard. Combined with optimized screw configuration and barrel insulation design, the comprehensive power saving rate can reach more than 25%. At the same time, the waste heat recovery module developed by it can efficiently recover the shear heat generated during processing for material preheating, further reducing energy consumption. This energy-saving module has become an optional configuration for high-end models and is widely used in large-scale production projects.
