Mold, a variety of molds and tools used in industrial production for injection molding, blow molding, extrusion, die casting or forging, smelting, stamping and other methods to obtain the required products. In short, a mold is a tool used to make a molded object. This tool is made up of various parts, and different molds are made up of different parts. It is mainly through the change of the physical state of the forming material to achieve the processing of the shape of goods, known as the "mother of industry" title.

With the development of China's industrial manufacturing, after decades of accumulation of die and mould manufacturing technology, die and mould products are gradually applied to all walks of life, showing the development trend of horizontal and horizontal depth synchronous expansion. Under the background of the improvement of mold manufacturing technology and the increasingly fierce market competition, mold products are gradually widely used in the transportation equipment mainly represented by automobile, and light industrial products mainly represented by home appliances, consumer electronics and plastic products.

Application of mold in automobile industry
The development of the automobile mold industry is closely related to the development of the automobile industry. The steady and rapid development of the automobile industry will greatly promote the development of the automobile mold industry. Moulds belong to consumables, the consumption is large, more than 90% of the parts in the automobile industry are formed by moulds, and cold, hot and plastic moulds are used at the same time. The average consumption of moulds is 0.12 tons per 10,000 cars. Under normal circumstances, the manufacture of an ordinary car itself needs about 1500 molds, including nearly 1000 stamping molds and more than 200 interior parts molds.

According to the calculation of professional institutions, automobile moulds account for about 1/3 of the market share of the mold industry, and according to the statistical data of the National Bureau of Statistics, the sales revenue of China's automobile moulds in 2017 was 266.342 billion yuan, according to the calculation of 2017 China's automobile mould market scale reached 88.8 billion yuan. By 2023, China's automobile production will reach nearly 41.82 million, with an average annual growth rate of about 6.0%, and the demand for automobile moulds will reach about 500 tons.

Application of mold in consumer electronics industry
With the increasing consumption level of people, the demand for consumer electronic products continues to expand, the replacement of products is accelerated, and the market size of consumer electronic products continues to grow, while driving the rapid development of die-related industries. In 2015 alone, the global consumer electronics market, driven by the rapid growth of smartphones, tablets, PCS and other terminal devices, reached nearly 790 billion euros, up 1.5 percent from the previous year, the data showed.

The continuous growth of the scale of China's electronic information industry has formed a manufacturing system with a relatively complete range of products and industrial supporting basis. According to the data of the National Bureau of Statistics, the sales revenue of China's electronic information industry reached 15.4 trillion yuan in 2015, with an increase of more than 10.4%. China's large-scale electronic information manufacturing industry achieved sales value of 113,294.6 billion yuan, up 9.0% year on year. The output of major products such as mobile phones and integrated circuits reached 1.81 billion units and 108.72 billion units, up 7.8% and 7.1% year-on-year, respectively. Consumer electronics such as mobile phones, personal computers and tablets account for more than 50 percent of global production, firmly occupying the world's no. 1 position. During the 13th Five-Year Plan period, the demand for molds in the consumer electronics industry will still show a steady upward trend.

Application of mold in home appliance industry
With the increasing improvement of living standards, the demand for household appliances in China has maintained a steady and rapid development. According to the data, from 2011 to 2016, the main business revenue of China's home appliance industry increased from 11,01.575 billion yuan to 1,460560 billion yuan, with a compound annual growth rate of 5.80%. The total profit of the industry increased rapidly from 51.162 billion yuan to 119.690 billion yuan, with a compound annual growth rate of 18.53%.
China's home appliance industry has formed a perfect component independent supporting system and created a complete upstream and downstream industry chain. Most parts of home appliance products depend on injection molding. Industrial cluster provides a good external environment for mold industry and home appliance industry to form a linkage effect. Experts predict that with the gradual development of home appliance products to the direction of intelligent, personalized and lightweight, the iteration speed of home appliance products is obviously accelerated, and the market of home appliance industry will still maintain a stable growth trend in the future.

conclusion
The die and mould industry belongs to the basic industry of the national economy. At present, China is in the transition period of industrial structure. The national target planning for emerging industries is to strive to reach about 15% of the proportion of the added value of strategic emerging industries in the GDP by 2020. In order to reach the target of 15%, among the seven strategic emerging industries, high-end equipment manufacturing industry will be vigorously developed as the pillar industry of the national economy in the future, and the mold industry, the mother of modern industry, will benefit from the development of high-end equipment manufacturing industry and obtain rapid development.
