Shenzhen automotive electronics industry is growing spurt
The output value ranks first in the country for two consecutive years, with an average annual growth rate of over 37%; the market share of car audio, GPS positioning system, retarder, sensors and other products top the list
[Reported by this reporter] (Reporter Chen Ying) The Shenzhen Electronics Industry Association’s report released yesterday revealed that Shenzhen’s automotive electronics industry is experiencing a growth in blow-out, with the two-year output value ranking first in the country, with an average annual growth rate of over 37%. . Industry sources said that a number of automotive electronics companies that have been born in Shenzhen in recent years have become domestic leaders, and the automotive electronics industry in Shenzhen, which has a good industrial base, has a bright future.
A group of domestic leading companies emerged
It is understood that the current domestic automotive electronics industry is in its infancy, and the Shenzhen automotive electronics industry has developed rapidly. It has a certain economic scale and is showing a high growth trend. Among the city’s dozens of companies that research and develop automotive electronics products, Hangsheng, SEG Navigation, Terjia, and Yuanzheng Science and Technology are presenting a momentum of rapid development, ranking among the leading domestic counterparts.
According to the survey conducted by the Automobile Electronics Branch of the Municipal Information Industry Association, the market coverage of Hangsheng car audio in the country is as high as 85%, and the market share is 22%. In 2004, the output value was 1.2 billion and the output value in 2005 is expected to reach 1.8 billion yuan. Huaqiang Information, SEG Navigation, and several companies engaged in GPS/GSM since the beginning of the year have accounted for about 80% of the domestic market share. Terjia's market share of car retarder is 80%, ranking first among domestic counterparts and second in the world. The output value of 2005 is expected to be 150 million yuan.
Automotive sensor is a key component of automotive electronics. China has just started. Shenzhen Shengwei’s product market share ranks first in the industry.
The person in charge said that with BYD entering the field of electric vehicles, Shenzhen has made considerable progress in the vehicle industry.
The automotive electronics industry is well established
At present, Shenzhen has accumulated a great deal of experience for the development of the automotive electronics industry. Through various forms such as cooperation, introduction, joint ventures, and processing, it has accumulated a large number of basic conditions such as capital, technology, talent, and industrialization capabilities. According to the global estimation of automotive electronic information products account for 1/3 of the total amount of electronic information products, the total output value of Shenzhen's automotive electronic products currently accounts for only about 3.7% of the total output value of the information industry, and there is a huge space for development.
According to reports, the Huaqiang Group and Sanyo joint venture car DVD laser head products have been produced for many years, technology, industrialization experience has matured, through a certain way of cooperation, is likely to become a complete set of global car DVD laser head manufacturers. The Pearl River Delta Electronic Industry Base, with Shenzhen as the main window, has also become more mature and has strong supporting capabilities. In addition, the promotion of e-commerce in China's auto industry is imperative. Shenzhen is also a strong software city and has unique advantages in e-commerce construction.
Industry insiders believe that Shenzhen's auto industry, especially its product development level, still has a big gap with developed countries. It needs to innovate and improve in emulation, and finally it can freely absorb and integrate the operational level of international technology and integrate the industry into the international economic cycle. .
Strength companies have gone abroad
At present, Shenzhen's powerful automotive electronics companies have stepped out of the country, or cooperated with foreign giants, or the products into the international market, such as Jinghua Electronics and Japan's Sanyo cooperation in the production of car audio, Hang Sheng Electronics and France Reo cooperation in the production of automotive safety control Products and so on.
It is reported that with the introduction of the "Shenzhen Automotive Electronics Industry Development Plan", the city's policies to support the development of the automotive electronics industry will soon be released, and Konka, Skyworth, TCL, China Merchants Dichen, Yushchenko, Jinzheng, Tongzhou and other IT companies are marching in succession. Automotive electronics. From the latest situation, the Shenzhen automotive electronics industry has entered a benign and rapid development track.
There are different kinds of technology to roll the metal plate:
Four-roller machines have a top roll, the pinching roll, and two side rolls.
The flat metal plate is placed in the machine on either side and "pre-bent" on the same side. The side rolls do the work of bending. The pinching roll holds the plate.
Three-roller machines (variable pitch aka variable geometry) have one pressing top roll and two pressing side rolls.
The three-roll variable pitch works by having all three rolls able to move and tilt. The top roll moves in the vertical plane and the side rolls move on the horizontal plane. When rolling, the top roll presses the metal plate between the two side rolls. The advantage of having the variable three roll is the ability to roll many thicknesses and diameters of cylinders.
For example; The side-rolls are what produce the mechanical advantage. With the side rolls all the way open, one has the maximum mechanical advantage. With the side rolls all the way in, you have the least mechanical advantage. So, a machine has the capability of rolling 2-inch-thick material with the maximum mechanical advantage, but a job is only 1/2 inch thick. Reduce the mechanical advantage and one has a machine that can roll from 1/2 to 2 inches thick.A plate rolling machine is a machine that will roll different kinds of metal sheet into a round or conical shape. It can be also called a [roll bending machine", [plate bending machine" or [rolling machine".
