In recent years, China's pump valve casting industry has developed rapidly, but there are still a lot of problems. Due to the long-term price war in the domestic pump and valve industry, the pump and valve industry has been stuck in the middle and low position of the world's valve industry for a long time. Therefore, our country's valve and valve industry must start from changing the competition mode and change the weak status of China's pump and valve industry.
China's valve casting industry has developed rapidly, but its overall level is still low, its product technology content is low, and key Valves also rely on imports. China's existing valve level is at least 10 to 20 years behind that of the internationally advanced countries.
There are still many defects in quality management in China. First of all, the process is more or less neglected. Many companies clearly have a quality assurance system, but they have no place in practical work. Quality management is performed by itself, arbitrary; secondly in the assembly process. It is also sloppy. It is no wonder that some valves have appeared running, running, dripping or leaking as soon as they are installed. Another example is the backwardness of many domestic enterprises' production equipment, which has remained at the level of the 70s to 80s of the last century. Some equipment has already passed the service life and is still running at full capacity. How can the quality of product processing be guaranteed? With limited funds, CNC and machining centers have also been added one after another. However, the number of companies that form CNC MACHINING has not been large in the industry so far, accounting for only about 20%.
