Analysis of the present situation of precision casting industry
Guiyang foundry believes that casting is one of the main methods to obtain mechanical products blank, and it is an important basic technology in the machinery industry and plays an important role in the national economy. The present situation of China's foundry industry is that the production is big, the annual output is about 36 million 500 thousand tons, the factory is more than more than 20 thousand, and the workers of the foundry industry are more than 1 million 200 thousand. A major feature of China's foundry industry is the rapid development of township enterprises since the reform and opening up, which has become an important force in the foundry industry of China. The number of points in the township foundry has exceeded the state-owned foundry point, and the output of castings in the township foundry point accounts for about half of the total output of the country's castings.
当前世界上工业发达国家铸造技术的发展归纳起来大致有四个目标，即：①保护环境，减少以至消除污染；②提高铸件质量和可靠性，生产优质近终形铸件；③降低生产成本；④缩短交货期。 我国铸造行业除厂点多,从业人员多,产量大以外,与发达国家相比,在质量、效率、能源与材料消耗、劳动条件与环境保护等方面都存在差距。造成这些差距的原因是铸造厂点规模小，经济实力差，工艺和设备落后，管理水平低，从业人员素质不高。 为了消除这些差距，为了满足我国经济建设的需要，也为了铸造行业自身的存在与发展，我国的铸造行业应以提高铸件质量和经济效益为中心，面向国内和国际两个市场；加强管理，打好基础，提高企业素质；调整产业结构，合理配置资源，提倡适度规模经营；继续以适用先进的生产工艺和技术装备改造铸造行业，实现清洁化生产，保证可持续发展。
The current development of industrial countries in the world of casting technology mainly has four objectives, namely, protect the environment, reduce and eliminate pollution; improving the quality and reliability of the production of high quality castings, near net shape castings; reducing production cost; shortening the delivery time. The China foundry industry in addition to plant points, the number of practitioners, large output, compared with the developed countries, in terms of quality, efficiency, energy and material consumption, labor conditions and environmental protection etc. there is a gap. The reasons for these gaps are small size of the foundry plant, poor economic strength, backward technology and equipment, low management level and low quality of employees. In order to eliminate the gap, in order to meet the needs of China's economic construction, but also for the existence and development of foundry industry, foundry industry in China should improve the casting quality and economic benefits as the center, the two domestic and international market; strengthen the management, to lay a good foundation, improve the quality of the enterprise; the adjustment of industrial structure, reasonable the allocation of resources, promote the appropriate scale of operation; to continue to apply the advanced production technology and technical equipment transformation of foundry industry, to achieve clean production, to ensure the sustainable development. The
1 效益是企业发展的基础 发展的基础是效益，发展又是为了实现更高的效益。中国应该有一个高效益的铸造业。没有效益的企业连生存也是困难的，更谈不上发展。为了提高效益，应从以下几方面着手： ①减员增效与节能降耗。 ②实现专业化生产。 ③采用新技术，实现科学管理。
1 benefit is the basis of the basic development of the development of the enterprise is the benefit, and the development is to achieve higher efficiency. China should have a high efficiency casting industry. Unprofitable enterprises are also difficult to survive, not to talk about development. In order to improve the efficiency, we should start from the following aspects: (1) reducing the efficiency of the staff and reducing the energy consumption. To achieve professional production. (3) adopt new technology to realize scientific management.
2 质量是企业的生命 质量和效益有时看似矛盾，但两者是统一的。产品质量低劣的企业终究是不能立足的，更谈不上效益,也不可能持续发展。提高产品质量需从以下几方面着手： ①合理选购原辅材料，正确制订及严格执行有关的工艺规程。 ②采用新技术、新工艺、新设备、新材料。 a.加强计算机技术在铸造生产中应用的研究。 b.在砂型铸造中采用高硬度及高均匀度的铸型,发展与推广相应的工艺与设备。 c.发展近净形及净形铸造成形新工艺。 d.发展液态金属处理及净化的新工艺新技术，优化材料性能。 e.发展机械化自动化，以保证铸件质量的稳定性、均一性，改善劳动条件。 f.加强铸造环保设备的研究和应用。 ③具有一支稳定的高素质的从业人员队伍。
The 2 quality is that the quality of life and the benefit of the enterprise sometimes seem contradictory, but the two are unified. In the end, the poor quality of the product can not be foothold, not to mention the benefit, nor can it continue to develop. In order to improve the quality of products, we should start from the following aspects: 1. Select and purchase the raw and auxiliary materials rationally, correctly formulate and strictly enforce the relevant technical regulations. New technology, new technology, new equipment and new materials are adopted. The research and application of computer technology in casting production to strengthen the a.. The B. with high hardness and high uniformity of the casting in sand mold casting, development and promotion of technology and relevant equipment. C. develops a new process of near net shape and net shape casting. D. has developed a new technology and new technology for the treatment and purification of liquid metals to optimize the properties of the materials. E. develops mechanization automation to ensure the stability and uniformity of the quality of the castings and improve the working conditions. F. strengthen the research and application of foundry environmental protection equipment. (3) a stable and high-quality workforce.
3 实现清洁化生产 清洁化生产是可持续发展的基本要求。清洁化生产的含义是：实现尽可能低的资源(原材料)与能源消耗；实现宜人化的生产环境及最低或零污染物排放;生产清洁化的产品(产品耗能、耗材少,易于再生复用及符合人机工程要求)。铸造的清洁化生产,主要是应用新技术、新工艺、新材料、新设备以实现低消耗、低污染或者无污染及铸造生产的宜人化环境等方面
3 the clean production of cleaner production is the basic requirement of sustainable development. The meaning of cleaner production is to achieve the lowest possible resources (raw materials) and energy consumption, to achieve the pleasant production environment and the lowest or zero pollutant emissions; to produce cleaner products (less energy consumption, less consumption, easy to reuse and meet Ergonomics requirements). The clean production of foundry is mainly based on the application of new technology, new technology, new materials and new equipment to achieve low consumption, low pollution or no pollution and the pleasant environment of foundry production.
