China’s 3K small tow carbon fiber and 50K large tow carbon fiber manufacturers expand production Hay:D01JLTG

From the largest in China to the largest in the world


On April 28, one of the 200,000 tons of carbon fiber entire industrial chain project: JLTG Carbon Fiber Technology Group's annual production of 150,000 tons of carbon fiber precursor project was officially launched. After 10 years of technological innovation, quality upgrades, market development and capacity expansion, JLTG carbon fiber precursor production capacity has begun to move from the largest in the country to the largest in the world.

The 150,000 tons of raw silk project is a basic project of the industrial chain. It is planned to invest 2.144 billion yuan to build 12 large tow raw silk production lines, which will be constructed in three phases. All will be completed and put into operation in 2025, with an additional output value of 3.7 billion yuan. In 2011, JLTG put into production at that time China's largest annual output of 5,000 tons of carbon fiber precursor project. After 10 years of development, the production capacity of JLTG carbon fiber precursor has reached 50,000 tons, and the product quality has been upgraded from T300 to T400, and some products can reach T700. The Chinese market share exceeds 90%.

Company manager Zhang Haiou introduced that the new project will mainly produce large tow carbon fiber products of 50K and above, which are mainly used in wind power blades, rail transit, sports and leisure products and other fields. The project plans to invest 2.144 billion yuan to add 12 new raw silk production lines. After it is completed and put into production, it is estimated that the new output value will be over 4 billion yuan.

The 150,000-ton carbon fiber precursor project started this time is divided into three phases, each with four spinning lines. The total investment in the first phase of construction is expected to be 950 million yuan. Starting from March next year, these four spinning lines will be put into operation one after another. We plan to have the entire 150,000-ton carbon fiber precursor project completed and put into production before the end of December 2025, and the profit is expected to reach more than 600 million yuan.


In March of this year, the JLTG high-performance carbon fiber carbonization line with an annual output of 300 tons was successfully commissioned. The production line started construction on July 13, 2020, and mainly produces 3K small tow carbon fiber, which can be widely used in high-end civilian fields such as wind power generation, lightweight automobiles, and clean energy.
