China's Mould And Die Industry Is Gradually Moving Towards The Era Of Standardization

- Jan 04, 2019-

The research, development and production of die standard parts are being carried out in an all-round and in-depth way. The product types, varieties, specifications, as well as the technical performance and quality level of products have been significantly improved. At present, the level of standardization and application of die and mould in China is still relatively low, optimistic estimate is less than 30%, compared with developed countries (70-80%) abroad, there is still a big gap.

 

Now, although the number of manufacturers is increasing year by year, most of them are small-scale, outdated equipment, backward technology, high cost and low efficiency. Only ordinary small and medium-sized standard die holders and plastic die holders, guide pillars, guide sleeves, push rods, die springs, pneumatic components and other products, with a high degree of commercialization, can basically meet the needs of the domestic market, and some exports.

 

But those products with high technology, advanced structure, excellent performance, superior quality and convenient replacement, such as ball-lock quick change punch and fixing plate, solid lubrication guide plate and guide sleeve, wedge mechanism and its components, high-grade plastic mould standard parts and nitrogen main spring, etc., are seldom produced in China. Due to lack of funds, technical transformation projects are difficult to implement. The production efficiency is low, the delivery cycle is long, and the contradiction between supply and demand is increasingly prominent.

 

There is a popular saying in the world that "first-class enterprise system standard, second-class enterprise make brand, third-class enterprise make product". The standardization degree and application level of die and mould is an important symbol to measure the level of a country's die and mould industry. All developed countries attach great importance to standardization work, such as Japan, the United States, Germany and so on. The standardization work of moulds in these countries has a history of nearly one hundred years. A perfect system has been formed for the revision of moulds standard and the production and supply of moulds standard parts.

 

Mould is a special forming tool product. Although it has strong personality, it is also an industrial product, so standardization work is very important. Every country with more developed industry attaches great importance to standardization because it can bring quality, efficiency and benefit to industry. The survival and development of China's die and mould standard parts industry is facing serious challenges. But as long as we are united, united, face the reality, accelerate reform, seize opportunities, meet challenges, survive in competition and rely on scientific and technological progress for development, we are confident that in the near future, fundamental changes will take place in China's die and mould standard parts industry, ushering in a better future.

 

Standard parts of dies are an important part of dies and the basis of dies. It has very important technical and economic significance for shortening the design and manufacturing cycle of the die, reducing the production cost of the die and improving the quality of the die.

The experience of developed countries abroad proves that the specialized production and commercial supply of standard parts of dies and moulds have greatly promoted the development of dies and moulds industry. According to foreign information, the wide application of standard parts can shorten the design and manufacturing cycle by 25-40%, save the social working hours caused by user-made standard parts, reduce the waste of raw materials and energy, lay the foundation for the application of modern technology such as die CAD/CAM, and significantly improve the manufacturing accuracy and performance of the die.

 

Usually, the standard parts manufactured by specialization will improve their matching accuracy and position accuracy by at least one order of magnitude compared with the standard parts manufactured by ourselves, and can ensure interchangeability and improve the service life of the mould, thus promoting the reform of the internal economic system, operating mechanism, industrial structure and production management of the industry, realizing specialization and large-scale production, and driving the commodity of the standard parts of the mould. The formation and development of the market. It can be said that without the specialization and commercialization of die standard parts, there will be no modernization of die industry.

 

At present, the business model of die and mould industry in our country is becoming increasingly prominent. On the premise of database construction and standard formulation, enterprises develop manufacturing management system suitable for their enterprises on the basis of software platform. With the realization of equipment automation and unit automation, fixture optimization, group automation of processing machinery, data tracking of processing parts are solved, and process automation is realized. The production scheduling automation and assembly automation will eventually realize the pipeline production of die and mould enterprises have emerged, and die manufacturing formally entered the era of standardization.

 

Therefore, a considerable number of die standard parts need to be imported from abroad every year, and their cost accounts for about 3-8% of the annual imports. There are still many problems in the technical standards, scientific and technological development, product quality and other aspects of domestic die standard parts. For example, product standards are confused, functional components are few and technical content is low, applicability is poor; technological transformation is small, equipment is obsolete, technology is backward, specialization level is low, product quality is unstable; professionals lack, management is not up to date, production efficiency is low, delivery cycle is long; production and sales outlets are unevenly distributed, operating varieties and specifications are small, and supply is insufficient; some units in order to compete for the market. The market is full of fake and inferior commodities. There are also phenomena such as cost-free, blind price reduction and market disruption, which need to be carefully studied and solved.

 

Overall, the development prospects of China's standard parts industry are very optimistic, and the standard parts industry will go to the world.
