Chinas mold industry is gradually moving towards the era of standardization
The research, development and production of mold standard parts are in full swing, regardless of product type, variety, specification, or technical performance and quality level of the product. At present, the standardization level and application level of China's molds are still relatively low, optimistically estimated to be less than 30%, compared with foreign industrialized countries (70-80%), there is still a big gap.
Although the production and sales companies are increasing year by year, most of them are small in scale, outdated equipment, backward in technology, high in cost and low in efficiency. Only ordinary small and medium-sized standard die frames and plastic mold frames, guide columns, guide sleeves, push rods, mold springs, pneumatic components and other products have a high degree of commercialization, which can basically meet the needs of the domestic market and have some exports.
And those with high technical content, advanced structure, excellent performance, high quality and convenient replacement, such as ball lock type quick-change punch and fixing plate, solid lubricating guide plate and guide bush, wedge mechanism and parts thereof , high-grade plastic mold standard parts and nitrogen main springs, etc., there are very few domestic manufacturers, and due to lack of funds, technical transformation projects are difficult to implement, production efficiency is low, delivery cycle is long, and the contradiction between supply and demand is increasingly prominent.
There is a popular saying in the world called "first-class enterprise standard, second-class enterprise as brand, third-rate enterprise to make product". The standardization degree and application level of mold is an important indicator to measure the level of a country's mold industry. Countries with more developed industries attach great importance to standardization work, such as Japan, the United States, Germany, etc. These countries have nearly 100 years of mold standardization work, the revision of mold standards, and the production and supply of mold standard parts. Formed a sound system.
Mold is a special forming tool product. Although it is highly personalized, it is also an industrial product, so standardization work is very important. Countries with more developed industries attach great importance to standardization because they bring quality, efficiency and efficiency to the industry. The survival and development of China's mold standard parts industry is facing serious challenges. But as long as we are united, united and united, face the reality, accelerate reform, seize opportunities, meet challenges, survive in competition, and rely on scientific and technological progress for development, convinced that in the near future, China's mold standard parts industry will fundamentally occur. Sexual change will usher in a better tomorrow.
Mold standard parts are an important part of the mold and are the basis of the mold. It has very important technical and economic significance for shortening the mold design and manufacturing cycle, reducing the mold production cost and improving the mold quality.
The experience of foreign industrialized countries proves that the specialized production and commercial supply of mold standard parts greatly promotes the development of the mold industry. According to foreign data, the wide application of standard parts can shorten the design and manufacturing cycle by 25-40%; it can save social working hours caused by user-made standard parts, reduce waste of raw materials and energy; can be modern technology such as mold CAD/CAM The application lays the foundation; it can significantly improve the manufacturing precision and performance of the mold.
Usually, the use of professionally produced standard parts, the accuracy and positional accuracy of the self-made standard parts will be increased by at least one order of magnitude, and the interchangeability can be ensured, the service life of the mold can be improved, and the internal economic system, operation mechanism and industry of the industry can be promoted. Reform in structure and production management, to achieve specialized and large-scale production, and to promote the formation and development of mold standard parts commodity market. It can be said that without the specialization and commercialization of mold standard parts, there is no modernization of the mold industry.
At present, China's mold industry business model has become increasingly prominent. Under the premise of database construction and standard setting, the company has developed a manufacturing management system suitable for the enterprise on the basis of the software platform. With the realization of equipment automation and unit automation, It has solved the optimization of fixtures, the automation of processing machinery group, and the data tracking of processed parts. After the process automation, the production automation and assembly automation will finally realize the production line of the production line. The mold manufacturing has officially entered the era of standardization.
Therefore, it is still necessary to import a considerable number of mold standard parts from abroad each year, and the cost accounts for 3-8% of the annual mold import. The domestic mold standard parts still have many problems in terms of technical standards, technology development, product quality, etc. . For example, the product standards are chaotic, the functional components are few and the technical content is low, the applicability is poor; the technical reform is small, the equipment is outdated, the process is backward, the level of specialization is low, the product quality is unstable; the professional talent is lacking, the management cannot keep up, and the production efficiency is low. The delivery period is long; the production and sales outlets are unevenly distributed, the operating specifications are small, and the supply is insufficient; some units compete for the market, do not talk about quality, shoddy, and shoddy goods flood the market. There are also phenomena that do not count costs, blindly cut prices, and disrupt the market. They need to be carefully studied and urgently needed to be resolved.
Overall, the development prospects of China's mold standard parts industry are very optimistic, and the standard parts industry will go global.
