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.
當前世界上工業發達國家鑄造技術的發展歸納起來大致有四個目標，即：①保護環境，減少以至消除污染；②提高鑄件質量和可靠性，生產優質近終形鑄件；③降低生產成本；④縮短交貨期。 我國鑄造行業除廠點多,從業人員多,產量大以外,與發達國家相比,在質量、效率、能源與材料消耗、勞動條件與環境保護等方面都存在差距。造成這些差距的原因是鑄造廠點規模小，經濟實力差，工藝和設備落后，管理水平低，從業人員素質不高。 為了消除這些差距，為了滿足我國經濟建設的需要，也為了鑄造行業自身的存在與發展，我國的鑄造行業應以提高鑄件質量和經濟效益為中心，面向國內和國際兩個市場；加強管理，打好基礎，提高企業素質；調整產業結構，合理配置資源，提倡適度規模經營；繼續以適用先進的生產工藝和技術裝備改造鑄造行業，實現清潔化生產，保證可持續發展。
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 效益是企業發展的基礎 發展的基礎是效益，發展又是為了實現更高的效益。中國應該有一個高效益的鑄造業。沒有效益的企業連生存也是困難的，更談不上發展。為了提高效益，應從以下幾方面著手： ①減員增效與節能降耗。 ②實現專業化生產。 ③采用新技術，實現科學管理。
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 質量是企業的生命 質量和效益有時看似矛盾，但兩者是統一的。產品質量低劣的企業終究是不能立足的，更談不上效益,也不可能持續發展。提高產品質量需從以下幾方面著手： ①合理選購原輔材料，正確制訂及嚴格執行有關的工藝規程。 ②采用新技術、新工藝、新設備、新材料。 a.加強計算機技術在鑄造生產中應用的研究。 b.在砂型鑄造中采用高硬度及高均勻度的鑄型,發展與推廣相應的工藝與設備。 c.發展近凈形及凈形鑄造成形新工藝。 d.發展液態金屬處理及凈化的新工藝新技術，優化材料性能。 e.發展機械化自動化，以保證鑄件質量的穩定性、均一性，改善勞動條件。 f.加強鑄造環保設備的研究和應用。 ③具有一支穩定的高素質的從業人員隊伍。
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 實現清潔化生產 清潔化生產是可持續發展的基本要求。清潔化生產的含義是：實現盡可能低的資源(原材料)與能源消耗；實現宜人化的生產環境及最低或零污染物排放;生產清潔化的產品(產品耗能、耗材少,易于再生復用及符合人機工程要求)。鑄造的清潔化生產,主要是應用新技術、新工藝、新材料、新設備以實現低消耗、低污染或者無污染及鑄造生產的宜人化環境等方面
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.
