[Project Background] Large twin-screw extruders in polypropylene production lines are critical equipment, traditionally monopolized by European manufacturers such as Germany's Coperion and Italy's LCI. The polypropylene unit (with an annual capacity of 500,000 tons) owned by 俄罗斯某公司 is one of the world's largest single-line polypropylene plants, demanding extremely high quality from its extruders.

[Role of the Chinese Enterprise] Zhangjiagang Chemical Machinery (JCZH) leveraged its technological breakthroughs in the R&D and manufacturing of large twin-screw extruders to successfully pass the rigorous certification tests of 俄罗斯某公司. It supplied the critical large twin-screw extruders for the polypropylene unit, breaking the long-term monopoly held by European manufacturers.

[Scope of Service] L3 equipment supply, manufacturing and supplying large twin-screw extruder units for polypropylene pelletizing, including the main extruder and supporting pelletizing and cooling water circulation systems.

[Typical Significance] The entry of China's independently developed large twin-screw extruders into the supply chain of the world's largest polypropylene plant is a significant milestone marking China's transition from 'following' to 'running alongside' in the field of specialized chemical equipment. This holds great importance for enhancing the competitiveness of Chinese chemical equipment in the global high-end market.
