In recent years, with the rapid development of the automobile industry, electronic information, home appliances, building materials and machinery industries, China's mold industry has also achieved rapid growth, according to relevant statistics, the total sales of China's mold industry rose from 98 billion yuan in 2009 to 184 billion yuan in 2016, the compound annual growth rate reached 9.58%. From 2009 to 2017, China's annual import of molds is about 2 billion US dollars. According to statistics, as of 2017, China's mold self-sufficiency rate was only about 60 percent, with a large part still relying on imports. What does mold mean for "Made in China"? Take the automobile as an example. The total number of molds needed in the manufacturing process of a car is more than 20,000.

Dong Mingzhu not satisfied with China's auto industry?

Dong Mingzhu thinks that the mold actually symbolizes an advanced industry. To enter the mold, is to hope that China's mold to re-understand themselves. Maybe we did not realize that mold is very important before.

"To tell the truth, I am not satisfied with China's automobile industry. Where is the dissatisfaction? Simply because it lacks precision. Because there is no accurate mold, it can not be so exquisite, and its running-in match, there is a gap. So at this time you will see that Chinese cars are a little shoddy, but your cost has not actually reduced much."

Dong Mingzhu's attention to the mold industry people are very excited!

Zhou Qunfei, chairman of Lens Technology Co., Ltd. is one of the suppliers of Tesla, has visited the Tesla factory, the car glass has such a wide gap, why is the outside called the horn, the inside feels like blowing the horn in the ear, it really can not prevent the sound. Originally, Zhou Qunfei had used the experience of watches to make mobile phones, and now he wants to use the experience of mobile phones to make cars. Now I see their requirements, basically 10 to 15 silk, before was one or two hundred silk tolerance.

Huangshan said that Dong Mingzhu's attention to the mold, the mold industry people are very excited. Mold industry it is a small industry, the total sales of about a year in China is about 250 billion, not very big, so many industries do not pay attention to it.

The manufacturing process of a car may require a total of more than 20,000 molds? How do the

molds play a role in the production process of a car?

Huang Shan, president of the Guangdong Mechanical mold Technology Promotion Association, told us that 20,000 sets of auto molds, the concept is from the total number of auto parts, in fact, the daily model replacement is about 2000 sets. The 2600 sets include die-casting mold, stamping mold and injection mold.

And the technical difficulty is relatively high is large complex, small precision, high speed, high precision, long life, which is also Gree motor of this kind. The fourth type is multi-cavity, multi-material, composite process molding.

The Germans have said that the mold of Gree can be the same as the mold made by Germans!

Dong Mingzhu added that when Gree's mold was displayed in Germany, a German said, "I did not think that the mold made by you Gree can be the same as that made by us Germans." In fact, often these words are a great inspiration to us, we have always thought that a manufacturing country in China, a large population, but you do not have the ability to master the core technology, how do you talk about your real manufacturing country.
