Dot peen marking works by electromechanically striking a carbide or diamond stylus assembly against the surface of a part to be marked.For example,dog tag engraver.The result is a succession of dots to create digits, text, logos, and 2D data matrix codes. Each such dot is the result of a pulsed current that runs through a solenoid, punches a magnet toward the surface, and subsequently returns the stylus to its starting position, awaiting the next pulse. Because each pulse occurs in only a fraction of a second, an entire 2D data matrix code, for example, can be completed in seconds (depending on the size).
Compressed air is not required.

Among the 21 major projects identified in Hefei City, 6 industrial projects and 3 energy projects have been launched, with a total investment of over 30 billion yuan. The start-up of these projects will intensify the Hefei “industry building a city†strategy, which will enable the city to achieve significant development in the fields of automobile manufacturing, steel smelting, power generation and other industries and energy, and will become an important support for the leap-forward development of Hefei City.
Hefei Automotive Industry Base is ready to appear
It is understood that relevant departments are currently working out plans for the planning of the Hefei Automobile Industry Base, and the preliminary work is being carried out intensively. This move can be said to have sounded the horn of Hefei to build a local large-scale automobile industry base.
The major projects launched by the Jiangqi Group include: the passenger car project will produce 60,000 BMPV passenger cars annually, 100,000 A-series sedan cars, 50,000 B-class sedan cars, etc.; commercial vehicle 100,000 light-duty trucks will be changed, Construction of 30,000 light buses, construction of specialized vehicles (trucks, dump trucks) and new areas; auto parts and components of 100,000 automatic transmissions, etc.; and construction of automotive R&D centers, logistics bases, and JAC universities. Jiangqi Group Corporation expects to produce 210,000 vehicles in 2007. It plans to reach a scale of 450,000 vehicles by 2010 and realize sales revenue of 40 billion yuan. The implementation of the project in 2008 will be of great significance to improving its level of engineering technology and manufacturing in the country and expanding the Hefei automobile industry.
At the same time, Hefei Changhe Automobile Co., Ltd. is also about to launch a technical transformation project for the entire vehicle production line. The main construction contents of the project include: construction of stamping, welding, painting, assembly and inspection process lines, and a production capacity of 100,000 vehicles/year. At the end of 2007, it plans to complete an investment of 150 million yuan. It is expected that the project will be completed and put into operation by the end of September 2008, and the project will increase output value by 3.6 billion yuan after it reaches production.
It is also known that a large foreign investment automobile industry related project with an investment of 240 million U.S. dollars will soon enter the Hefei market. It will start in November 2008 and be completed and put into production in 2010. It is estimated that the investment for the project in 2008 will reach approximately US$ 44.04 million. The three major energy projects create a total investment of 11.65 billion yuan for the expansion of the three major power plants of Hefei Power. This is a key project that will accommodate the increase in the power load in the province and the Central Guizhou Province and will play an important role in Anhui's energy base in the East China Power Grid. The pressure on electricity supply in Hefei area promotes the coordinated development of economy and society.
among them:
The main construction contents of the expansion project for the No.5 unit (1×600MW) in Hefei Power Plant include: the use of the existing site of the Hefei Power Plant to expand a 1×600MW supercritical coal-fired generating unit, and the simultaneous construction of a desulfurization unit, leaving room for denitrification facilities. And there is room for expansion of 6# machine (1×600MW), with a total investment of 2.5 billion yuan. The project has been approved by the National Development and Reform Commission and started construction in January 2007. By the end of October, an accumulated investment of 500 million yuan has been completed and the planned construction period will be December 2008.
The expansion project of 6# unit (1×600MW) of Hefei Power Plant is located on the east side of the expansion end of the 5# unit of the power plant, with a planned capacity of 1×600MW coal-fired generating units, and simultaneous construction of flue gas desulfurization, denitrification and other environmental protection devices. The total static investment is 1.949 billion yuan. Strive to start construction in 2008, put into operation in 2010.
Hefei No.2 Power Plant Phase 2 2×1000MW unit project is located in Feidong. It is planned to build a 2×1000MW supercritical coal-fired unit in the first phase of the project expansion, and reserves for further expansion. The project is planned to start in 2008, and around 2011. One unit was put into production.
Diesel engine base will settle in Economic Development Zone
In the area east of Lianhua South Road and north of Pahe River in the Economic Development Zone, Hefei City initially plans to build a very substantial diesel production base with a total investment of approximately RMB 2.6 billion, which will be constructed in two phases, including: 1.5 million horsepower marine low-speed diesel engines. After the project is completed and put into production, it can annually produce 3 million horsepower of high-power and low-speed diesel engines, with an output value of approximately RMB 6 billion.
While a large number of industrial projects have been launched, Masteel (Hefei) will strive to start construction of deep processing of steel products in 2008 in order to ensure high-quality, adequate steel resources for industries with potential for development such as automobiles, home appliances, machinery, and construction. The project will eliminate the iron and steel smelting and primary steel production capacity of Maanshan Hefei Iron and Steel Company, expand the steel deep processing production line, and finally form a production capacity of 1.89 million tons of steel deep processing. The total investment of the project is 5.4 billion yuan. The construction period is 2 years. It is expected that a sales income of 10 billion yuan will be formed after the project is completed. At present, the "Masteel restructured steel structure adjustment plan" program has been submitted to the National Development and Reform Commission Industry Division review. The project will re-position and structurally adjust Maanshan Iron & Steel's main business, and promote the company's optimal allocation, industrial upgrading and competitiveness.
Notable Characteristics:
