The development and prospect of precision casting parts industry

At present, China has formed a group of technology and management gradually on the track of international operation, familiar with the international market precision casting industry, they led the rapid development of the industry.In 2012, China accounted for 28.4% of the world's total output of castings per thousand us dollars.

1, the domestic market is increasing with the rapid development of China's economy makes an expansion of the domestic market of the precision casting, such as the rapid development of auto industry to drive the car with precision casting products production and brand promote quickly, the development of housing industry makes building hardware surge in demand, investment enterprises in China directly purchase parts from the region, who is the market order into the domestic market order, etc.

After more than 20 years of efforts, some enterprises have been able to mass produce machine parts with certain precision requirements and high-quality aviation precision castings, and have the ability to challenge commercial parts in terms of technology and cost performance. The export volume has been increasing year by year.With the deepening of global economic integration and global procurement, exports will continue to grow at a high speed.According to the statistics of the goods listed as casting products in the import and export data of the customs, the export volume of all kinds of castings in China in 2012 was 1.978 million tons, which was slightly lower than that in 2011.The total amount of China's casting exports in 2012 was 2.97 billion us dollars, up slightly from 2.81 billion us dollars in 2011.

One of the advantages of precision casting is that it can produce a variety of alloys and very complex, thin-walled castings. The casting size is high, the surface roughness is low, and it can achieve little or no cutting processing, which is incomparable to sand casting and forging.With the improvement of parts requirements, more and more sand castings or forgings will be replaced by precision castings.With the continuous improvement of the industrial chain of China's precision casting parts industry and the continuous improvement of the technical level, the demand for precision casting parts in the downstream demand field keeps increasing. It can be seen that the output of China's precision casting parts will continue to show a steady growth trend in the next few years.China's output of precision casting parts is expected to reach 4.6 million tons by 2021.Halide precision casting production forecast 2016-2021 years with the rapid development of economy in our country makes the expanding domestic market of the precision casting, such as the rapid development of auto industry to drive the car with precision casting products production and brand promote quickly, the development of housing industry makes building hardware surge in demand, investment enterprises in China directly purchase parts from the region, who is the market order into the domestic market order, etc.Downstream demand areas for precision casting parts only increased.It can be seen that in the next few years, the market size of China's precision casting industry will continue to show a steady growth trend.By 2021, the market size of China's precision casting parts industry is expected to be close to 285 billion yuan.Market size forecast of China precision casting parts industry from 2016 to 2021

Investment die casting industry must adhere to the road of sustainable development

Europe and the United States and other advanced countries due to the casting cost high, and out of the requirements of environmental protection, pollution have big sand cast gradually transferred to developing countries, although there is no sand casting precision casting industry industry pollution to the environment, but there are large amounts of waste water waste gas emission, therefore, the precision casting industry in China must be in environmental protection, product structure, management, etc, make great efforts one time, adhere to the sustainable development path.

1, promote the automation of process equipment, intelligent and environmental protection, drive the process of environmental protection at present, China precision casting technology and equipment manufacturing level there is a considerable gap, including molding, shell making, smelting, finishing and other process equipment after a disparity between the automatic and intelligent level and international level, including facilities, at the same time, from design to production process of the means of environmental protection is difficult to eliminate the hazard sources.This is common in many different types of businesses.Mainly including a large number of dust, toxic and harmful gas and waste residue, waste discharge.In this respect, the country and the industry have some standards, the most active method has two: one is to establish a unified industry of raw and auxiliary materials, equipment, facilities, environmental protection standards, as a die-casting enterprises enter and the industrial structure adjustment mandatory industry regulations, and extend to the industrial chain.Second, the government introduced mandatory technical regulations and incentive policies to guide enterprises to take active actions, increase investment in environmental protection and upgrade.Enterprises that have not passed the certification of the environmental management system shall be rectified within a time limit, and obtain the certification qualification. Enterprises that have passed the certification shall be given appropriate financial and tax policies.

It is the common responsibility of Chinese precision casting enterprises to improve product structure and product quality.First, through the introduction and development of pure alloy purification equipment, technology, improve metallurgical quality;Second, by using solidification simulation software to pay attention to casting process design, improve the primary yield;Third, strictly control the manufacturing process, increase investment in mold making, shell making materials and process equipment, and strive for the effective operation of the quality system;Fourth, through the establishment and enrichment of casting correction and modification equipment and cleaning equipment not easy to damage the casting, strengthen the post-treatment process, make the casting more precise and beautiful;Fifthly, improve the nondestructive testing equipment of castings and enhance the quality assurance ability.

3, precision casting products to achieve "three", strive to "fine, excellent, light, heavy, green" direction of the development of "three" : namely, lean - to consume the least resources to make value-added products, even products into art;Serialization -- according to the market layout, "do something, do nothing", divide the existing products into series, develop new products to demonstrate systematically, reflect the broad spectrum and the direction of enterprise strategy development;Modularization -- horizontal extension of existing products to meet the needs and value of users, to achieve the product-oriented to technology-oriented transformation, further improve the market competitiveness of products."Precision" means precision and accuracy."Excellent" means no defect;"Lightness" is the lightness of structure and material;"Heavy" is important;"Green" means clean production, green casting.This is an important measurement index for precision casting enterprises to enhance their core competitiveness.

4, the introduction of computer information management, improve the level of enterprise management at present, some enterprises in addition to technical problems, often cause delay delivery, inventory control, material consumption, low efficiency and so on various aspects, the introduction of computer management and lean thinking helps enterprises to better play to the efficiency of people, goods, content, thus improve castings quality, reduce cost, the maximum to meet customer requirements, and adapt to the change of market demand.Vigorously deepen the application of computer in precision casting production, including ERP, CRM, CAD, PDM, CAE, and so on, and gradually realize simulation design, manufacturing, online trading and remote development.Chinese precision casting enterprises should accelerate the pace of information construction.

Due to the shortage of labor resources and the change of environmental protection, the casting of developed countries is also transferring to developing countries. After China's accession to the WTO, the export situation of precision casting is more favorable.From the current situation, the foreign orders of foreign-funded enterprises are much more than domestic orders, and direct orders, that many domestic enterprises are very unfamiliar with the international market, foreign market development lack of talent, lack of investment, do not understand the rules of international market operation, there was no substantive breakthrough at the beginning, also did not do big.Therefore, in the development of the international market to achieve the "three necessary" : first, it is necessary to make good use of international media to publicize themselves, understand others;Second, it is necessary to go abroad to participate in exhibitions, develop more direct customers;Thirdly, it is necessary to establish the concept of "lean and honest" to develop and expand the business with customers.In exploring the international market, China's precision casting industry should first strengthen unity, exchange information and regulate behavior.Second, to choose a good enterprise product positioning and development positioning, do not blindly follow.The industry association should play a positive role in guiding the whole industry chain of precision casting to develop in an orderly direction, improving the level of China's precision casting industry on the whole, and realizing sustainable development.
