A survey of the implementation of the classification measures in the standardiz

Where the industry is more developed countries, the standardization of the work of great importance, because it can bring quality, efficiency and effectiveness of the industry. Mold is a special forming tool products, although strong, but also an industrial product, so the standardization of work is very important. The standardization work of the mold mainly includes the formulation and implementation of the technical standard of the mold, the production and application of the standard parts, the propaganda, the implementation and the promotion of the relevant standards.
China mold standardization work started late, together with the promotion, implementation and promotion of the work of small, so the mold standardization is behind the production, more backward in many industrial countries in the world. Abroad mold developed countries, such as Japan, the United States, Germany, etc., mold standardization work has been nearly 100 years of history, the development of mold standard, mold standard parts of the production and supply, has formed a perfect system. And the standardization of China's mold is only f-rom the National Standardization Technical Committee established in 1983 after the beginning of the.
At present, China has about 2 million production units of the mold, mold production have great development, but with industrial production requirements compared to still can not adapt to, which is one of the important reasons is mold standardization level is not high.
China's mold standardization system includes four categories of standards, namely: the basic standards of the mold, mold quality standards, mold parts standards and technical standards related to mold production.
Mold standard and according to the mold is divided into stamping standard mold, plastic injection mold standard, die-casting mold standard, forging mold standard, fasteners cold heading mould standard, standard wire drawing dies, cold extrusion standard mould, rubber mold standard, glass molds and automotive stamping die standard etc. ten categories.
At present, China has more than 50 mold standard a total of more than 300 standard numbers and automotive stamping die parts and components of 14 kinds of common devices and 244 varieties, a total of 363 standards. The formulation and implementation of these standards, improve the standardization of China's mold and the level of standardization.
With the increase of international communication and development of the localization of the imported mold and foreign-funded enterprises on the supporting die with the requirements of this international standard is proposed, on the one hand, in the standard s-etting pay attention to try to adopt international standards and foreign advanced standards, including the adoption of advanced enterprise standard.
On the other hand, many mold standard parts production enterprises according to the market needs, in addition to the standard parts of the production of Chinese standard parts, but also by foreign advanced enterprise standard production mold standard parts. For example, Japan's "Futeba", "DME", the German "Haas test", the standard has been widely popular in Chinese.
The concept of "standardization of mold standardization" which is often mentioned in the mold industry is more complicated, and is not commonly used in the mechanical industry ". The latter can generally be used to measure the rate of standard parts, and the former often refers to the use of mold standard parts coverage". Due to the late start of China's mold standardization work, mold standard parts production, sales, promotion and application of the work is also relatively backward.
Therefore, the mold standard parts varieties specifications, supply is not timely, poor matching and other issues exist for a long time, so that the use of mold standard parts coverage has been low. In recent years, although the foreign investment enterprises involved, the proportion has been greatly improved, but overall is still very low.
According to preliminary estimates, the current ratio is roughly between 40% to 45%. And the international general in more than 70%, of which more than 80% small and medium-sized mold. Due to the nature of the Chinese mold enterprises and different regions, the use of standard parts of the mold coverage is very different. Foreign funded enterprises than other enterprises, the enterprises should the South than the North high. This is the most obvious performance in Guangdong. Guangdong to focus a large number of foreign-funded enterprises, they led to the transformation of other ideas of enterprises and market development and Guangdong enterprises die mold standard parts using the coverage rate is much higher than in other parts of the mold enterprise.
Implement the mold standard, using the standard parts, not only can effectively improve the quality of the mold, but also can reduce the mold production cost and greatly shorten the mold production cycle.
