Guangdong New Energy Bus Exceeds 30,000 in 2012
The 25th World Conference on Pure Electric Vehicles, Hybrid Electric Vehicles and Fuel Cell Vehicles (EVS25) was held on November 5, 2010 in Shenzhen, China. The theme of this conference and exhibition is the “Sustainable Power Revolutionâ€. . Jointly discuss and exchange the development strategies, policy orientations of various governments, as well as supporting infrastructure construction, enterprise market development, and application of new technologies, discuss research and innovation of high-end and cutting-edge technologies in the industry, and build economic and technical cooperation and exchanges for the international electric vehicle industry. platform. The following is the speech delivered by Zhu Xiaodan, Member of the Standing Committee of the Guangdong Provincial Party Committee and Executive Vice Governor of Guangdong Province, at the opening ceremony of the Sustainable Power Revolution Forum. Moderator: The following please the Standing Committee of the Guangdong Provincial Party Committee, Deputy Governor of Guangdong Province, Zhu Xiaodan speech! Zhu Xiaodan: Distinguished leaders, ladies and gentlemen, ladies and gentlemen, friends, today the 25th World Electric Vehicle Conference was grandly opened in Shenzhen Special Economic Zone. I would like to express warm welcome to the guests attending the meeting on behalf of the People’s Government of Guangdong Province. We would like to express our heartfelt thanks to the organizers and contractors of the conference and friends at home and abroad who have always cared about and supported the economic and social development of Guangdong. This year's event was unprecedented, with participation in reviews, representatives, exhibitors, and exhibition areas creating the world's largest ever electric car conference, which will set a new milestone in the development of electric vehicles worldwide! In today's world, climate change has become a severe challenge faced by all humanity. Controlling greenhouse gas emissions and promoting green development have increasingly become global consensus and concerted action by all countries. As a major developing country, China has made tremendous efforts to respond to climate change from the height of its responsibility to the world and mankind. The Chinese government has already determined and made a commitment: By 2020, China's gross domestic product (CO2) emissions have fallen by 40% to 45% compared to 2005. As the province with the largest economic aggregate in China, Guangdong has the responsibility and ability to make due contributions to achieving this goal. Since the birth of new energy vehicles represented by electric vehicles, profound changes have taken place in automotive energy technologies, which has made us see the hope that the world’s most popular means of transport can effectively reduce emissions and realize low-carbon development. Guangdong Province attaches great importance to the development of electric vehicles. After years of efforts, it has initially established an electric vehicle as a leader, a power battery as the core, and an electric motor and electric control as the foundation, supporting the charging and electric auxiliary systems, and using electric vehicles. Demonstrate the development pattern of electric vehicles for market promotion. The Guangdong Electric Vehicle Action Plan and the Guangdong Guangdong Provincial New Energy Vehicle Demonstration Scale Program have been promulgated and a batch of electric vehicle manufacturers are pushing ahead. I think 12 cities, including Guangzhou, Shenzhen, and Zhuhai, will fully launch demonstration activities for the promotion and application of new energy vehicles. It is estimated that by 2012, the total number of new energy bus demonstrations in the province will exceed 30,000, and the production and promotion of electric passenger cars will also be accelerated. In the near future, our province will prepare a new energy automobile industry plan for Guangdong Province and strive to build Guangdong into an important electric vehicle industry base in China and even the world in ten to fifteen years. The holding of the electric car conference will inject new impetus into the development of electric vehicles in Guangdong. We will fully learn from and learn from the successful experience of developing electric vehicles in various countries, and earnestly hope to receive the attention and guidance from participating experts. We sincerely invite domestic and foreign universities, scientific research institutions and friends from all walks of life to visit, cooperate and invest in Guangdong. . The prospects for the development of electric vehicles in the world are worth looking forward to and are infinitely bright. I sincerely wish the conference a complete success and wish all the guests good health and all the best. Thank you!

Casting Parts:
The casting is a metal human control of hot working
process relatively early, has a history of about 6000 years.In early 1700 BC to
1000 China has entered into casting heyday era,the technology has reached a
very high level.
the material to be casting is usually solid
but heated to a liquid metal (copper, iron, aluminum, lead, tin, etc.), and
mold materials can be sand, metal and even ceramics. In response to different
requirements, the use of the method will be different.

Category:
Casting blank is almost forming, which
achieves the goal of free machining or less processing, reduces cost and
reduces production time to a certain extent. Casting is one of the basic
processes in modern equipment manufacturing industry.
(1) Sand casting:
Using sand as the mold material, also known
as sand casting, foundry, including wet sand, dry sand and chemical hardening
sand 3, but not all are available in sand casting. Advantage is low cost,
because of the use of the mold sand can be reused; drawback is the mold
manufacture time-consuming, repeated use casting model is not possible. To
damage can be achieved after the finished product.
(2) Special Casting Process:
According to the special casting molding
materials can be divided into natural mineral sand as the main materials (such
as casting, mud casting, shell casting, vacuum casting, mold casting, ceramic
mold casting, special casting and metal) as the main cast materials (such as
metal casting, pressure die casting, continuous casting, low pressure casting,
centrifugal casting, etc.
2.1 Metal mold casting method: using high
melting point is the raw material made of metal mold. The subdivision for
gravity casting, low pressure casting and pressure casting method. By casting
the melting point can be cast metal has also been limited.
2.2 Lost wax casting method: this method
can for membrane casting and solid casting. First the object copy the required
casting wax, and then dipped into ceramic containing (or silica sol) in the
pool and stay dry, the wax replica covered with a layer of ceramic membrane,
repeating the steps until the outer membrane is sufficient to support the
casting process (about 1/4 inch 1/8 inch), wax melting in the mold, and out of
the mould. Then many times to enhance the mold temperature, the hardness can be
used to rear casting.
Based on different casting raw material,we`ve
Steel Die Casting,copper alloy die casting and aluminium alloy die casting.
Processing:
(1)The mold preparation (liquid metal become
a solid container for casting ) according to the material used can be divided
into sand, metal, ceramic, clay, graphite, according to the frequency of use
can be divided into single type, semi permanent and permanent mold preparation,
quality is the main factor affecting the quality of castings;
(2) The melting and casting;:casting metal
(alloy) mainly include all kinds of cast iron, cast steel and casting of
nonferrous metal and alloy castings;
(3) The processing and inspection: casting
processing including removal of the core and the casting surface removal of
foreign body, riser, shovel thorn and sanding fash protrusions and heat
treatment, plastic. Anti rust and rough machining.
