In recent years, along with our countrymould The rapid development of industry, mould parts standardization, specialization and commercialization, have a high level, has made considerable progress.Since 1983 the national mold Standardization Technical Committee was established, and organize experts to formulate and revise the examination on the mold standard, issued a total of 90 standards, including die standard 22, more than 20 plastic mould standard. These standards are issued and implemented, promoting technological progress and development of mold industry, has great social benefits and economic benefits.
Modelstandard parts The research, development and production is a comprehensive in-depth, whether it is product types, varieties, specifications, or technical performance and product quality are improved significantly. At present, China's mold standardization level and application level is still relatively low, optimistic estimates of less than 30%, and the developed countries (70-80%), there is a big gap.
China's mold industry is gradually moving toward standardization Era
Now the production and sales of manufacturers is increasing year by year, but most of them are small scale, obsolete equipment, backward technology, high cost and low benefit. Only the ordinary small and medium-sized standard die and plastic mold base, a guide pole and a guide sleeve, a push rod, die springs, pneumatic components and other products, commercialization, can basically meet the needs of the domestic market, and some export.
And those with high technical content, advanced structure, excellent performance, good quality, convenient replacement of personalized products, such as ball lock fast exchanging punch and fixed plate, solid lubrication guide and guide sleeve, a wedge mechanism and its parts, high-gradePlastic mold Standard parts and the main nitrogen spring in the domestic manufacturers is very little, and because of lack of funds, project difficult to implement, the production efficiency is low, the delivery cycle is long, the contradiction between supply and demand have become increasingly prominent.
There is a popular saying called "international standards of first-class enterprise, enterprise brand, three flow of enterprise products". The degree of standardization and application level of the mold is an important symbol to measure a country's level of mold industry. All industrial developed countries, attaches great importance to the standardization work, such as Japan, the United States, Germany and other countries, the mold standardization work in nearly 100 years of history, the production and supply of mold standard revision, the standard mold, has formed a perfect system.
The mold is a special forming tool products, although personalized, but also industrial products, so the standardization work is very important. All industrial developed countries, attaches great importance to the standardization work, because can bring quality, efficiency and benefit for industrial. The survival and development of our country in the standard mold industry is facing a serious challenge. But as long as we unite to face reality, to accelerate the reform of one heart and one mind, seize the opportunity, meet the challenge, in order to survive in the competition, relying on scientific and technological progress and development, believe that in the near future, China's mold standard fundamental change industry will usher in a better tomorrow.
Standard mold is an important part of the mold, the mold is based. It is to shorten the cycle of mould design and manufacture, reduce production cost, improve the quality of mold mold has a very important significance in technology and economy. Foreign industrial experiences of the developed countries, the standard mold specialized production and commodity supply, greatly promoted the development of mold industry. According to foreign materials, widely used standard parts can shorten the cycle of design and manufacture of 25-40%; because users can save homemade standard parts caused by the social work, reduce the waste of raw materials and energy; lay the foundation for the application of mold CAD/CAM and other modern technology; can significantly improve the accuracy and performance of mould manufacturing. Usually the use of specialized production of standard parts than homemade standard parts with the precision and position accuracy will be increased, and ensures the interchangeability, improve the service life of the mold, and then promote the industry economic system, management system and industrial structure and physical aspects of the production management reform, realize specialization and scale the production, and promote the formation and development of mold standard parts of the commodity market. It can be said without the standard mold specialization and commercialization, there is no mold industry modernization.
The current operation mode of China's mold industry has become increasingly prominent, in the premise of making database construction, standard, enterprise software platform based on the two development of suitable manufacturing management system of the enterprise, with the realization of automation equipment and automation unit, in solving the fixture optimization, processing machinery automation, data processing group tracking after the implementation, process automation, production automation and assembly automation will eventually achieve the production line of die mold manufacturing enterprises have emerged, officially entered the era of standardization.
Therefore, every year still need to be imported from abroad a number of mold standard parts, the cost of imports accounted for about 3-8% years mould. Domestic mold standard parts in terms of technical standards, technology development, product quality, there are still many problems. Such as product standards confusion, functional elements and less technical content is low, poor applicability; technical innovation, obsolete equipment, backward technology, low level of specialization, product quality is not stable; professionalpersonnel The lack of poor management, low production efficiency and long delivery cycle; production and sales outlets are unevenly distributed, operating specifications less shortage; some units in order to compete for the market, not quality, shoddy, shoddy goods flooding the market. And regardless of the cost, blindly cut prices and disturb the market phenomenon, the need to seriously study, to be solved.
