On August 18th, the latest business data disclosed by China Chemical Equipment Technology Group showed that its independently developed five composite rubber extrusion linkage production line had a year-on-year increase of 42% in export volume in half a year, and had won over 200 million yuan in orders from global leading enterprises such as Michelin and Linglong Tire. Its products have covered 26 countries and regions, and its global market share has remained stable at first place. This breakthrough marks the complete breaking of the decades long technological monopoly of European enterprises in the field of high-end composite extrusion equipment in China.
As the core equipment for high-performance tire production, the five composite extruder can achieve synchronous extrusion and composite molding of five different rubber materials, with extremely high requirements for equipment accuracy and stability. Through 70 years of technological accumulation and continuous research and development, Chinese chemical equipment has not only overcome key technologies such as independent control of multiple temperature zones and closed-loop pressure feedback regulation, but also controlled the extrusion accuracy of the equipment within ± 0.15mm, and increased the MTBF to 6800 hours, which is 15% longer than similar international products. In Guangxi's first large-scale production line for civil aviation tires, the company provided key equipment such as twin-screw extrusion presses and tread composite extrusion production lines, which successfully achieved high-precision molding of 12 specifications of semi-finished aviation tires for 6 models, helping China's civil aviation tire manufacturing reach the world's advanced level.
The cost-effectiveness advantage of domestically produced equipment is significant, with prices only 60% of imported products under the same performance, and supply cycles shortened to less than 3 months. "Experts from the China Rubber Industry Association stated that with the explosive demand for high-end products such as new energy vehicle tires and aviation tires, the market size of high-end rubber extruders in China is expected to exceed 5 billion yuan by 2025, and the localization rate will increase to 75%.
