According to the latest statistics, there were more than 300 cemented carbide production enterprises in the country in 2012, with more than 30 professional research institutes and more than 25,000 employees in the whole industry. As of 2012, it has a capacity of 100,000 t/a of tungsten concentrate, a capacity of 180,000 t/a of tungstic acid and tungsten salt, a capacity of 62,000 t/a of tungsten carbide, and a capacity of 38,000 t/a of cemented carbide. And the supporting supply capacity of Co, Ni, Ta, Nb and Ti. In 2012, China's cemented carbide production was 23,500 tons, cemented carbide industry sales revenue was 20.9 billion yuan, cemented carbide exports nearly 5,000 tons, exports earned more than 360 million US dollars, and cemented carbide deep processing products reached 6,600 tons, accounting for total alloys. 1/3 of the output. The production of hard alloy products is basically complete, with more than 40,000 specifications and models. The output and varieties can basically meet the needs of various economic sectors in China.
The main problems in China's cemented carbide industry: First, the scale of enterprises is small, and the industrial concentration is not high. According to incomplete statistics, the average annual production capacity of 199 cemented carbide enterprises is 176 tons, the average annual output is only 86 tons, and only 4 enterprises with annual output of more than 1,000 tons. Second, there is less investment in science and technology, lack of high-end technical talents, and weak technical research and development capabilities. China's cemented carbide industry's investment in science and technology is less than 3% of sales revenue, the level of scientific and technological research and development is not high, and the original core technology results are less. Third, the product quality level is low and the product structure needs to be adjusted. China's cemented carbide production accounts for more than 40% of the world's total output, but cemented carbide sales revenue is less than 20% of the world's total, mainly due to high-performance ultra-fine alloy, high-precision high-performance abrasive coated blades, super-hard tool materials, complex The production of high value-added products such as large-scale products and precision hard alloy CNC tools is less, the deep processing is insufficient, and the varieties are incomplete.
With the rapid expansion of China's auto industry, the demand for cutting tools for auto parts processing is increasing, and the demand for hard alloys in China's steel, transportation, construction and other fields is growing. In the strategic picture of foreign cemented carbide multinational companies, the Chinese market has quietly changed from a supporting role to a protagonist.
By the end of the "Twelfth Five-Year Plan" period, China's cemented carbide production is expected to reach 30,000 tons, sales revenue will reach 30 billion yuan, and the output of deep-processed products will account for more than 40% of the total amount of hard alloys. Exports will double from the "Eleventh Five-Year Plan" and strive to exceed $1 billion. Cemented carbide will develop in the direction of intensive processing and tool matching; development in the direction of ultra-fine, super-thick and coating composite structure; development towards circular economy, energy saving and environmental protection; development towards precision and miniaturization.
Our company also provide Eco Gate. Eco gate's frame made from round tue of 30mm with post of 48mm. Inside mesh using for 100*50mm, zine phosphated(using Hot Dipped Galvanized before plastic coated) and green (RAL6005) powder coated. This gate is ideal for gardens or parks. It look more beautiful and neattly than Garden Gate for parks. But different parks need different size and style gate. We provide 3 types of this gate. It is including 1*1m, 1*1.2m, 1*1.5m. Eco-gate usually fixed Welded Wire Mesh( hot dipped galvanized inside).
