Because of the outstanding problems of the industry itself, the disadvantages of small and medium-sized enterprises began to appear after the crisis. It is reported that in 2009, the total output of castings in the country was 35.3 million tons, ranking first in the world for 10 consecutive years, increasing at an average annual rate of 10.9 tons, covering automotive, energy, machine tools, pipeline pump valves, aerospace, engineering machinery and other industries; However, the industry's problems are not optimistic: small enterprises, low industrial concentration, unreasonable product structure, weak independent innovation capabilities, backward equipment and processes, high investment, high consumption, high pollution, low efficiency, and low efficiency. The industrial foundation is still fragile.
In recent years, our country's valve production technology has made certain achievements, but our country's valve industry is limited by the casting technology level, casting steel, cast iron and other raw materials are wasted in the production process. Facing more and more fierce valve competition market and more and more intensive resource market, a large amount of waste in the casting link is not conducive to the cost savings of the valve industry in China, nor is it conducive to the long-term development of the valve industry in the fierce market competition. In order to save production cost and make more production space for valve industry, for the long-term healthy development of Valve industry, the valve industry in our country must avoid the waste of materials in the casting process. This can be achieved by raising the economy consciousness of casting workers; On the other hand, enterprises are required to increase their scientific research, develop new casting techniques or introduce new casting equipment to better avoid waste caused in the casting process, achieve the goal of saving production costs and increasing the ratio of input to output.
Due to the many outstanding problems in the Foundry industry itself, enterprises with backward production capacity will be phased out. Since the demand for castings in domestic and foreign markets can not be separated from small and medium-sized enterprises, a longer-term phase-out process will be required. However, the overall casting quality will gradually improve, which is a challenge for the downstream valve industry, increasing production costs and improving product quality. In the process of development of Foundry industry, Valve enterprises should pay attention to the influence of power restriction and emission reduction, shortage of labor, national policies, etc. on Foundry industry. At the same time, they should pay more attention to the development and changes of Foundry industry and make appropriate adjustments according to their own operating conditions!
