Overview of Mold Standardization in China
In countries where industry is more developed, importance is attached to standardization because it brings quality, efficiency, and efficiency to industry. Molds are specialized forming tools. Although they are highly personalized, they are also industrial products. Therefore, standardization is very important. The mold standardization work mainly includes the formulation and execution of mold technical standards, the production and application of mold standard parts, and the promotion, implementation and promotion of relevant standards. China's mold standardization work started relatively late, combined with small efforts in propaganda, implementation, and promotion, so mold standardization lags behind production, and it lags behind many industrially advanced countries in the world. Foreign mold developed countries, such as Japan, the United States, Germany, mold standardization work has been nearly 100 years of history, the formulation of mold standards, the production and supply of mold standard parts, has formed a complete system. The Chinese mold standardization work only started in 1983 after the National Standardization Technical Committee for Molds was established. At present, there are about 20,000 mold production units in China, and mold production has been greatly developed. However, compared with industrial production requirements, it is still unacceptable. One important reason is that the mold standardization level and level are not high.
China's mold standardization system includes four major categories of standards, namely: mold base standards, mold process quality standards, mold parts standards, and mold production-related technical standards. Die standards can be divided according to the main classification of die stamping die standards, plastic injection die standards, die casting die standards, forging die standards, fasteners cold die standards, drawing die standards, cold extrusion die standards, rubber die standards, glass products Die and car die standards and other top ten categories. At present, China has more than 50 standard molds, more than 300 standard numbers, and 14 general-purpose devices and 244 varieties for automotive die parts, with a total of 363 standards. The formulation and promotion of these standards have improved the standardization and level of Chinese molds.
With the increase of international contacts, the development of imported molds, and the development of international standard requirements for foreign investment in molds for foreign-funded enterprises, on the one hand, attention has been paid to the adoption of international standards or advanced foreign national standards, including the adoption of advanced technologies, in standard formulation. The company's standards; On the other hand, many mold standard parts production enterprises according to market needs, in addition to the production of standard mold parts in accordance with Chinese standards, but also in accordance with the standards of foreign advanced companies to produce mold standard parts. For example, the standards of companies such as Fuertoba in Japan, DME in the United States, and Haskau in Germany have become popular in China.
The concept of “standardization degree of molds†often mentioned in the mold industry is rather complicated, which is different from the “standardization degree†commonly used in the machinery industry. The latter can generally be measured by the adoption rate of standard parts, while the former is often referred to as the "use coverage of mold standard parts." Due to the late start of Chinese mold standardization work, the production, sales, promotion and application of mold standard parts are lagging behind. Therefore, there are many problems such as the lack of specification of mold standard parts, untimely supply, poor compatibility, etc., resulting in the use of standard mold parts. Coverage has been low. In recent years, although the proportion of foreign-funded enterprises has been greatly increased, it is still low overall. According to preliminary estimates, the current ratio is roughly between 40% and 45%. In the international community, it is generally over 70%, among which the medium and small molds are over 80%. Due to the nature of China's mold companies and the different regions in which they are located, there is a large difference in the coverage of mold standard parts. The foreign-funded enterprises are higher than other enterprises, and the enterprises in the south are higher than those in the north. This is the most obvious in Guangdong. Guangdong has concentrated a large number of foreign-funded enterprises. They have driven the transformation of other corporate concepts and the development of the market. As a result, the coverage rate of mold standard parts used in Guangdong's mold enterprises is much higher than that of mold enterprises in other regions. The implementation of mold standards, the use of standard mold parts, not only can effectively improve mold quality, but also can reduce mold production costs and greatly shorten the mold production cycle. Relevant statistical data show that the use of standard mold parts can save the company's mold processing time 25% -45%, can shorten the mold production cycle 30% -40%. With the development of many varieties, small batches, individuation, and rapid cycle production of industrial products, in order to improve the rapid adaptability and competitiveness in the market economy, the importance of mold standardization is even greater in today's increasingly important mold production cycle. major.
