The five-compound rubber extrusion line with a total length of more than 65 meters is the core equipment for the preparation of semi-manufactured parts of high-end tires, and it is also the most advanced and critical production process equipment for high-end green tires, mainly used for the processing, compounding and shaping of various rubber.
The quality of automobile tires directly determines the safety of drivers and passengers, and the quality of tires is inseparable from its production equipment and technology. With the economic and social development, China has become the world's largest tire consumption country, but also the largest tire producer and exporter, tire output has accounted for more than 1/3 of the world.
Even though we have become a major tire manufacturer, we are facing the bottleneck of heavy dependence on imports for high-end products. In 2012, the European Union introduced the "Labeling Law" for green tires and formulated relevant product standards, which put forward higher requirements for green tire manufacturing technology. Xie Lei, chairman of Guilin Rubber Design Institute Co., Ltd., told reporters that the world's top tire manufacturers have begun to tend to use five different rubber compound extrusion equipment to obtain better tread parts to meet the requirements of high-performance tires.
It is understood that the five-compound rubber extrusion unit is the core equipment for the production of high-performance tires. The equipment can compound extrude 5 different rubber compounds in the machine at the same time, which can effectively solve the problem of in-machine composite extrusion of the most critical tread components of tires, and ensure that the key tread parts meet the process requirements of high wear resistance, rolling resistance resistance and wet slip resistance. Before the emergence of this technology, the world's most advanced four compound rubber extrusion unit equipment was blocked by foreign companies, resulting in China's high-performance tires relying heavily on imports.
Guilin Rubber Design Institute Co., Ltd. as a long-term engaged in the design and production of tire manufacturing equipment enterprises, in the face of difficulties, five composite rubber extrusion unit technology research and development is imperative!
"At that time, only two German companies in the world proposed the concept of five composite rubber extrusion units, and the relevant intellectual property layout was not perfect." Our company actively participates in the technological competition and opens the technological breakthrough route of the research and development of the five-compound rubber extrusion unit with independent intellectual property rights." Xie Lei said that the company around the composite rubber extrusion technology in-depth research and innovation, lasted for many years to successfully overcome a number of key technical problems, and now the company developed five composite rubber extrusion unit has broken through the developed countries "jam neck" key core technology, Its core invention patent "five composite rubber extruder head" pioneered the double locking guarantee design and the parting surface and flow channel chamber design technology based on rubber viscoelastic characteristics, which solved the key technical problems such as high wear resistance and rolling resistance in the design and manufacture of green tire tread, and accelerated the pace of China's national brand green tire to the world.
At present, the equipment has been widely used in France Michelin, Hangzhou Zhongce and other international and domestic head enterprises in the global factory, and thus led the extrusion equipment series products to create the first place in global shipments, sales of the second place, the domestic market share reached 65%, ranking first in the domestic industry.
In 2022, the core patent of Guilin Rubber Design Institute Co., Ltd. "five composite rubber extrusion head" won the 23rd China Patent Gold Medal, which is one of the 30 gold MEDALS selected from more than 2 million effective invention patents in the country, and Guangxi won the highest honor in China's patent again after 21 years, which is of great significance to promote the localization of national major technology and equipment.
"In the future, Guilin Rubber Design Institute Co., Ltd. will further increase investment in research and development, and further research and development of composite rubber extrusion units to serialization, standardization, intelligence, digitalization, energy saving and high efficiency, and strive to achieve green tire green manufacturing."
