Casting is a long-established method of forming metal parts, which has been used for thousands of years since the Bronze Age. With the continuous development of science and technology, casting technology has been continuously improved, and new casting technology has emerged. However, due to the flexibility, versatility and low production cost of sand casting, it is still the main production commonly used by many foundry companies. method. According to incomplete statistics, castings currently produced by sand casting account for more than 85% of the total production.
China is a big casting country, but it is far from being a founding power. Mainly due to the quality of castings, production efficiency, utilization of natural resources, environmental protection, and production conditions, all of which lag behind economically developed countries. We must develop new casting forming technology suitable for China's national conditions, improve casting quality and reasonable. The use of resources to promote the progress of China's foundry technology and enhance the competitiveness of the international market is an urgent issue facing the foundry industry.
