Development history of injection molds in China

There is a popular saying in the domestic mold industry: "The big mold is looking for Huangyan, and the fine mold is looking for Yueqing". Yueqing is located in the south of Zhejiang, and its regional economy is relatively developed. China star enterprises such as Zheng Tai Group and Delixi Group are all in Yueqing. Liushi Town in this city is the famous capital of electrical appliances in China, and Hongqiao is the core base for manufacturing electronic components in China. Almost all household appliances in China have electronic components produced there, with an annual output value of over 7 billion yuan, accounting for 17% of the total industrial output value of Yueqing.

According to Lu Ouwu, president of Yueqing Mould Association, Yueqing mould industry started earlier and has experienced 30 years of development. At present, Yueqing has more than 42,000 mechanical mould industry teams, more than 20,000 mould processing equipment, wire cutting machines and more than 200 EDM machines/KLOC-0, ranking first in the country. In recent years, more than 500 famous machine tools and 17000 metalworking equipment from Switzerland, Japan, the United States and Germany have been introduced successively, and the total fixed assets of die processing equipment in the whole industry are nearly 2.7 billion yuan. Last year, the mold output value of this city was 3.2 billion yuan, which is the largest precision mold production base and the highest technical level in China.

Current mold technology level and market forecast in China.

The technical level of mold production is not only an important symbol to measure the manufacturing level of a country, but also determines the product quality, benefit and new product development ability of this country to a great extent.

At present, China's mold development and manufacturing level is at least 10 years behind the international advanced level, especially the contradiction between production and demand of large, precise, complex and long-life molds is very prominent, which has become a bottleneck seriously restricting the development of China's manufacturing industry.

Mould is the basic technological equipment of industry. Telecommunications, automobiles, motorcycles, motors, electrical appliances, meters, household appliances, building materials and other products more than 80%. Is formed by a mold. The high precision, high complexity, high consistency, high productivity and low consumption of products produced by molds are incomparable with other processing and manufacturing methods.

With the continuous development of China's industry, higher and higher requirements are put forward for molds. Therefore, the demand development of precision, large-scale, complex and long-life molds will be higher than the overall development speed.

Analysis: The development trend of China mold industry in the future.

According to the industry analysis, the future development trend of China molds includes 10:

First, the mold is getting bigger and bigger.

Second, the precision of the mold will be higher and higher. 10 years ago, the precision of precision molds was generally 5 microns, but now it has reached 2-3 microns, and molds with the precision of 1 micron will also be listed.

Third, the multi-functional composite mold will be further developed. In addition to stamping parts, the new multifunctional compound die also undertakes assembly tasks such as lamination, tapping, riveting and locking, which requires higher and higher performance of steel.

Fourthly, the proportion of hot runner mold in plastic mold will gradually increase.

With the continuous improvement and development of plastic molding technology, gas-assisted molds and molds suitable for high-pressure injection molding will also be developed.

Six, the application of standard parts will be increasingly extensive. Mold standardization and the application of mold standard parts will greatly affect the mold manufacturing cycle, improve the mold quality and reduce the mold manufacturing cost.

7. The prospect of rapid and economical molds is very broad.

8. With the development of lightweight products such as automobiles and motors, the proportion of die-casting dies will continue to increase. At the same time, the life and complexity of die-casting die will also be put forward higher and higher requirements.

9. The process of replacing steel with plastic and wood with plastic is further accelerated, and the proportion of plastic molds will continue to increase. Due to the increasing complexity and precision of mechanical parts, the requirements for plastic molds are getting higher and higher.

Ten, the mold technology content will continue to improve.
