Molds, various molds and tools used in industrial production to obtain the required products by injection molding, blow molding, extrusion, die casting or forging, smelting, stamping and other methods. In short, a mold is a tool used to make shaped items. This tool is composed of various parts, and different molds are composed of different parts. It mainly realizes the processing of the shape of the article through the change of the physical state of the formed material, and is known as the "mother of industry".

   With the development of China's industrial manufacturing, after decades of accumulation of mold manufacturing technology, mold products have been gradually applied to all walks of life, showing a development trend of simultaneous expansion of vertical and horizontal depth. In the context of the improvement of mold manufacturing process technology and the increasingly fierce market competition, mold products are gradually widely used in transportation equipment mainly represented by automobiles, and light industrial products mainly represented by home appliances, consumer electronics and plastic products.

 Mold application in the automotive industry

    The development of the automotive mold industry is closely related to the development of the automotive industry. The steady and rapid development of the automotive industry will greatly promote the development of the automotive mold industry. Moulds are consumables, with a large amount of consumption. More than 90% of the parts in the automotive industry are formed by molds. At the same time, cold work, hot work, and plastic molds are used. On average, every ten thousand cars consume 0.12 tons of molds. In general, it takes about 1500 molds to manufacture an ordinary car, including nearly 1,000 stamping molds and more than 200 interior parts molds.

Mold application in the consumer electronics industry

    With the increasing level of people's consumption, the demand for consumer electronics products continues to expand, product replacement is accelerated, the market size of consumer electronics products continues to grow, and at the same time drives the rapid development of mold-related industries. Data show that in 2015, the global consumer electronics market was driven by the rapid growth of terminal devices such as smartphones, tablets, and personal computers, reaching nearly 790 billion euros, an increase of 1.5% over the previous year.

 Application of mold in household appliance industry

     With the improvement of living standards, the demand for household appliances in China has maintained steady and rapid development. According to the data, from 2011 to 2016, the main business income of China's home appliance industry increased from 1.101575 trillion yuan to 1.605560 trillion yuan, with a compound annual growth rate of 5.80%; the industry's total profit increased rapidly from 51.162 billion yuan to 119.690 billion yuan, compounded annually The growth rate is as high as 18.53%.

    China's home appliance industry has formed a complete independent component matching system, creating a complete upstream and downstream industrial chain. Most parts of home appliances rely on mold injection molding. Industrial clustering provides a good external environment for the mold industry and the home appliance industry and other related industries to form a linkage effect. Experts predict that with the gradual development of home appliances in the direction of intelligence, personalization and light weight, the update iteration speed of home appliances is significantly accelerated, and the future market of the home appliance industry will still maintain a stable growth trend.

Conclusion

    The mold industry belongs to the basic industry in the national economy. At present, China is in the transition period of the industrial structure. The country ’s target plan for emerging industries is to add 15% of the value of strategic emerging industries to GDP by 2020. . To achieve the 15% share target, among the seven strategic emerging industries, high-end equipment manufacturing will be vigorously developed as the pillar industry of the national economy in the future, and the mold industry as the mother of modern industry will benefit from high-end equipment manufacturing Rapid development
