According to the overall goal of common prosperity, and ultimately to reduce the gap between what China will implement the western development strategy to boost the eastern part of the strategy of China's foundry industry to apply. Eastern China's foundry industry, because of their own geographical advantages support and national policies, a good development trend, the level of development is much higher than the western region of the foundry industry. For the implementation of the western development strategy, promoting Western economic development, we must promote the development of the western-based foundry industries, that the western economic takeoff reinforce the foundation. This requires the foundry industry in eastern China, with its more advanced technology, more solid financial advantage, management advantages, promote development of the western foundry industry, so as to achieve the overall goal of common prosperity. To solve the foundry industry in vicious competition problem, we must first solve the problem of existence of these foundries. Promote industrial upgrading of China's casting copper pieces, need to develop high-end casting, casting can change the structure of the development of high copper sets of copper casting industry, reducing the number of low-end foundry, reducing competitive pressure casting copper low-end product market manufacturers, so that the low-end market is gradually restored to the casting ordered state, one solution to the vicious competition. Advantages: 1, parts of complex shape can be produced die-cast copper pieces, especially for complex lumen blank; 2, wide adaptability, commonly used industrial metal materials can be cast, a few grams to several hundred tons; 3, a wide source of raw materials, low prices, such as steel scrap, scrap, chips and the like; 4, the shape and size of the part of the casting is very close to reducing the amount of cutting, are not cutting; 5, widely used agricultural machinery 40% to 70%, the machine 70 % to 80 wt% is cast. Disadvantages: 1, the mechanical performance than forged, such as organizing coarse deficit; 2, sand casting, single, small batch production, high labor intensity; 3, unstable casting quality, process more complex factors, Yi generating a number of drawbacks. Casting defects casting quality has a significant impact, therefore, for the selection of the cast alloy and casting methods to lay the foundation, we should start with the quality of the casting, and combined to form a casting major defects prevention.
