Development of Mold Standard Parts in 2011 and Trend Analysis

The degree of mold standardization and application level is an important indicator of the level of the mold industry. Molds are specialized forming tools. Although they are highly personalized, they are also industrial products. Therefore, standardization is very important. In countries where industry is more developed, importance is attached to standardization because it brings quality, efficiency, and efficiency to industry. The survival and development of the mold standard parts industry in China is facing serious challenges. However, as long as we unite and unite in one heart, we must face the reality, speed up reforms, seize opportunities, meet challenges, survive in competition, and rely on advancements in science and technology, convinced that in the near future, China's mold standard parts industry will take root. The revolution will usher in a better tomorrow.

The prospects for the development of China's mold standard parts industry are optimistic. The mold standard part is an important part of the mold and is the basis of the mold. It has very important technical and economical 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 professional production and commercial supply of mould standard parts has greatly promoted the development of the mould industry. According to foreign materials, the extensive application of standard parts can shorten the design and manufacturing cycle by 25-40%; it can save social hours due to user-made standard parts and reduce the waste of raw materials and energy; it can be a modern technology such as mold CAD/CAM. The application lays the foundation; can significantly improve the manufacturing precision and performance of the mold. Generally, the use of professionally produced standard parts will improve the matching accuracy and position accuracy by at least one order of magnitude compared with self-made standard parts, and ensure interchangeability, increase the service life of the mold, and then promote the internal economic system, operating mechanism, and industrial structure of the industry. The reform of production management has achieved specialization and large-scale production, and has driven the formation and development of the mold standard commodity market. It can be said that without the specialization and commercialization of mold standard parts, there will be no modernization of the mold industry.

In recent years, with the rapid development of China's mold industry, the standardization, specialization, and commercialization of mold parts have reached a relatively high level and significant progress has been made. Since the establishment of the National Mold Standardization Technical Committee in 1983, it has organized experts to formulate, revise, and review mold standards. A total of more than 90 standards have been issued, including 22 standard stamping standards and more than 20 plastic mold standards. The issuance and implementation of these standards have promoted the technological progress and development of the mold industry, resulting in great social and economic benefits. The research, development and production of modular standard parts are in full swing, regardless of product types, varieties, specifications, or the technical performance and quality levels of the products. According to Luo Baihui, CEO of Die & Mould Network, the current level of standardization and application of molds in China is still relatively low, with an optimistic estimate of less than 30%. Compared with foreign industrial developed countries (70-80%), there is still a large gap. Although production and sales companies are increasing year by year, most of them are small-scale, outdated equipment, backward technology, high cost, and low efficiency. Only ordinary small and medium standard punch die sets and plastic die sets, guide posts, guide bushes, push rods, die springs, pneumatic components and other products are highly commercialized, and they 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 have personalized products, such as ball lock type quick change punch and fixing plate, solid lubrication guide plate and guide sleeve, wedge mechanism and its components There are very few domestic manufacturers of high-grade plastic mold standard parts and nitrogen main springs. Due to the lack of funds, technical reform projects are difficult to implement, production efficiency is low, and the delivery period is long. The contradiction between supply and demand is increasingly prominent.

Therefore, a considerable amount of mold standard parts must be imported from abroad every year, and its cost accounts for about 3-8% of the annual mold import amount. There are still many problems in terms of technical standards, scientific and technological development, and product quality for domestic standard mold parts. For example, product standards are confusing, with few functional components and low technical content, poor applicability; small technological changes, obsolete equipment, backward technology, low level of specialization, and unstable product quality; shortage of professionals, poor management, and low production efficiency , Long lead times; uneven distribution of production and sales outlets, operating specifications and less variety, lack of supply; some units in order to compete for market, do not talk about quality, shoddy, shoddy goods flood the market. There is also the need to seriously study and urgently resolve the phenomenon of cost-cutting, blind price cuts, and disruption of the market.
