"Demon Frenzy" is not desirable Chinese mold standard parts should be changed

In countries where the industry is more developed, more emphasis is placed on standardization because it can bring quality, efficiency, and efficiency to the 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. Therefore, 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, etc., mold standardization work has been nearly 100 years of history, mold standard formulation, mold standard parts production and supply, has formed a complete system. However, the standardization of Chinese molds only started in 1983 after the establishment of the National Mold Standardization Technical Committee. At present, there are about 20,000 mold production units in China, and the mold production has been greatly developed. However, compared with the requirements of industrial production, it is still unacceptable. One important reason is that the level and level of mold standardization is 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 international standardization requirements of foreign-funded enterprises on their matching molds, 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 according to Chinese standards, but also in accordance with the standards of foreign advanced companies to produce mold standard parts. For example, standards for companies such as Japan's Fu Teba and Germany's Haskau have become widely 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 also lagging behind. Therefore, there are problems such as the lack of specification of mold standard parts, untimely supply, poor compatibility, etc., and thus the use of mold standard parts. Coverage has been low. Although this year has seen a large increase in the proportion of foreign-invested companies, it is still low overall. According to preliminary estimates, the current ratio is 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 the mold quality, but also can reduce mold production costs and greatly shorten the mold production cycle. Relevant statistics show that the use of standard mold parts can save the company's mold processing time 25% to 45%, can shorten the mold production cycle of 30% to 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.

Mold standard parts are suitable for socialized large-scale professional production, but China has long been scattered, chaotic and poor.

The so-called "dispersion" is mainly due to the excessive number of production sites of mold standard parts, and it is rarely able to form economic batches. The so-called “chaotic” is mainly due to the chaos of the standard. Enterprises often have to produce according to national standards, standards, and several standards and certain corporate standards in the past. They must also be established according to foreign standards such as Japan, Germany, the United States, Switzerland, and certain foreign countries. Enterprise's standard production. At the same time, the market for mold standard parts is also chaotic, and disorderly competition has caused many adverse consequences. The so-called "bad" is the poor quality of mold standard parts and the poor efficiency of enterprises. In recent years, with the intervention of foreign companies, although this situation has improved, it has not yet fundamentally changed. There is still a big gap between production and demand. Some companies do not work hard on quality and level, but only make a fuss about the price, resulting in excessive price cuts that result in cutting corners, mischiefs, and declining quality. As a result, many companies have reduced the overall profitability of mold standard parts, and some companies have even lost money. the edge of.

The sales process plays an important role in the market for standard mould parts. At present, although there are nearly 100 sales outlets in the country, most of them are small in scale, have little inventory, and have small sales. Even if they are more than 50 business units in the joint sales network of mold standard parts of China Die & Mould Industry Association Standards Committee, The same problem exists. Individual units plan to launch online sales and e-commerce, but this work will start soon and it will take time to form scale.

China's "fifteen" mold industry development plan put forward: mold standard parts to expand the variety, improve accuracy and achieve interchangeability. Among them, major types, such as formworks, guides, push rods, elastic components, etc., must be mass-produced on an economic scale. In 2005, the use rate of mold standard parts reached 60%, and in 2010 it reached over 70% (standardization of 60% of large-size mold parts), basically meeting the market needs, mold bases, guides, putters, push tubes, elastic components, standards Components, small standard components (such as standard male and female molds, sprue bushings, retaining rings, pull hooks, etc.) and hot runner components are the focus of development. We can see the arduous tasks and bright prospects of mold standardization and mold standard parts. The guiding ideology of the mold standardization work proposed by the Standards Committee of China Die and Mould Industry Association is: Standardization is the basis, and specialization is the direction. Commercialization is the key.
