Valve casting: the shortcomings of the industry have led to a large gap between China and the rest of the world.

as a national industry, China's valve casting industry has stopped liquidation in recent years. The annual development rate is particularly obvious in recent years. Although the development process has experienced ups and downs, on the whole, the development of the valve casting industry tends to be stable and rising. It has gradually become one of the industries with rapid development in China's domestic machinery industry. As a national industry, the valve casting industry in China has developed at a particularly rapid pace in recent years. Although the development process has experienced ups and downs, the development of the valve casting industry tends to be stable and rising on the whole. It has gradually become one of the industries with rapid development in China's domestic machinery industry

valve casting is the basis for the development of China's casting industry and the whole industry, and it plays a good role in promoting the development of China's national economy. According to the statistics of foreign countries with developed industries, the output value of valves is the sum of the economic benefits of compressors, fans and pumps, accounting for about 5% of the output value of the whole machinery industry. At the same time, as an important force of technical equipment, especially in metallurgy, petrochemicals, chemical industry, electric power, urban pipeline drainage, etc., valves play a key role. In recent years, China's infrastructure investment has been increasing, which has also brought great opportunities for valve casting

even so, the valve casting industry is also facing a series of problems that will occur in the development of China's industrial machinery industry: the industry development level is low, the product technology content is low, the product category is single, the quality is unstable, and there is no high-end product

at present, China's valve casting is still in a period of development. There is no core technology, automation control and sophisticated management team. As a result, compared with the foreign valve casting industry, there is still a long way from the fatigue limit - the material can withstand the maximum fluctuating stress with infinite cycle times. In the context of continuous development, why is the gap between valve casting and foreign valves so large? Here, the relevant experts give us four opinions: 1. Lack of technological innovation talents. The most fundamental reason is that the government or enterprises have not made efforts to cultivate talents. 2. There is no spirit of breakthrough in technology. 3. Gaps in quality management and equipment. 4. Gap in product production process. Based on the above four points, the gap between China's casting valves and foreign countries is becoming larger and larger
