China General Machine Components Industry Association has announced that General Machine Components Industry GDP grew only 6.4 percent last year, which is the lowest recent years, down from 12.1% in 2008. Fasteners and powder metallurgy industry even have negative growth of -1.5% and -2%. According to reports, General Machine Components industry output since 2006 has maintained a double-digit growth. China General Machine Components Industry Association said in 2012 the industry suffered the most difficult times in recent years, compared to the global financial crisis in 2008, the more serious problems encountered by industries and enterprises.
Founded in 1989, China General Machine Components Industry Association (CMCA) is a registered national industrial organization having the social entity as a legal person with the approval from the Ministry of Civil Affairs. It is voluntarily formed by the manufacturers, research institutes and related associations in the fasteners, gears, chains transmission, springs, powder metallurgy, and couplings industry.
In the complex domestic and foreign downturn grim development situation, on the one hand, enterprise development funding significantly increased; on the one hand, there was a dramatic decrease in corporate profits. Besides, fasteners suffered the international trade protection impact which results in the range of exports narrowed significantly; less order, upgrade, products optimization, green manufacturing, lack of funds, labor drain and other series of problematic issues, are pooled together in 2012.
China General Machine Components Industry Association also said that in last year, precision hardware has growth totally. The gear output value reached 195 billion yuan, a year-on-year increase of 9.5%; gear exports is relatively stronger which is $ 4.543 billion with an increase of 18.3%; precision parts manufacturer said that chains, springs and transmission joints basic sub-industry growth rates is 8%; however, fasteners, powder metallurgy industry has emerged negative growth, year-on-year growth of between -1.5 to -2%.
Association reported that the reason why fasteners and powder metallurgy industry has negative growth is that lack of market demand. Especially fasteners are suffered by the international anti-dumping, which caused export sales showed a downward trend.
However, China General Machine Components Industry Association believes that, the development of the industry has switched from the high-speed growth stage to the high-quality and stable growth period. And “from the forecast analysis trend of economic development in 2013 at home and abroad, the industry should be better in 2013 than in 2012”.

Solar LED Street Lighting Fixtures
Nearly 17 years ago, in the Caribbean purchased solar street lighting systems for areas around the neighborhood. Now, they purchased additional lights, to expand its existing installation. Technology has changed a lot, because the installation of the first light. Here A comparison technology then and now.
Solar LED Street Lights
The old-fashioned lamp use, the new design uses a compact fluorescent LED lamps. The cost of the new device is a little old style the Cobrahead device than, but rapid payment of the total savings from the use of LED fixture design. LED solar lights use about one-third of the generating capacity to provide the same lighting energy-saving lamps and last 5 times longer.
Solar LED Street Light Power System
With higher efficiency lighting available through LED technology allows for lower power consumption. The old solar lamp requires a large amount of electric power systems, street lighting from dusk to dawn. The lower electricity mini solar system does not need a powerful the one pole hurricane resistance to reduce the cost of the entire system up to 10%.
Solar LED Street Light Mounting Bracket
Finally, the installation of the new system is very different. The new T-top mounted using fewer resources, is easier to install and reduce wind resistance than before, this is great for hurricane-prone areas. Fixture installation curve, cone, upsweep straight tube stent compared to the old style, the architecture is more enjoyable.
It's always nice to see the advances in technology and changes over the years. After 17 years of service, the new system will apply to the great LED lights provide additional security by society. What other lighting technology changes has happened in the last decade and a half?
Led-solarlights.com integrates R&D, manufacture and export in LED solar lighting products like LED solar lights, solar home lighting system, solar mobile charger and solar Inverter. We are committed to provide innovative solar energy solution for catering to different market demand. With advanced technology, professional staff, advanced machines, strict quality control process and complete production process, our indoor solar lighting has been exported to India, Bangladesh, Australia, Solomon and South Africa etc...

Introduction to 304 Stainless Steel
304 stainless steel is a very common type of stainless steel, also known as eighteen-eighths stainless steel in this industry. Corrosion resistance of it is preferable to that of 430 stainless steel, but the price of it is cheaper than that of 316 stainless steel. 304 stainless steel is widely used in daily life, such as: high grade stainless steel cutlery, outdoor stainless steel railings and 304 stainless steel coil products.
Although this type of stainless steel is very common all over the world, but the name "304 stainless steel" came from the United States. Many people think that the 304 stainless steel is a model called in Japan, but strictly speaking, Japanese official call of 304 stainless steel is "SUS304". Currently, common indicating methods of this type of stainless steel on the market include 06Cr19Ni10, 304, and SUS304. Among them, 06Cr19Ni10 generally means Chinese standard production, 304 generally means ASTM standard production, and SUS304 means JIS standard production.
304 is a universal stainless steel. It is widely used for making equipment and parts require for good overall performance (corrosion resistance and formability). In order to maintain the inherent corrosion resistance of stainless steel, steel must contain more than 16% chromium and over 8% nickel content. 304 stainless steel is a mark of stainless steel produced in accordance with United States ASTM standards. 304 is equal to 0Cr18Ni9 stainless steel in China. (GB/T 20878-2007 has been changed to 06Cr19Ni10).
Product Standard
It is a very important parameter for 304 stainless steel, directly determining its ability to resist corrosion and its value. The most important element of 304 stainless steel is Ni and Cr, but they are not the only two elements. The specific requirements are stipulated by the product standard. Industry common decision situation finds that as long as the content of Ni is greater than 8%, and the content of Cr is greater than 18%, it can be regarded as 304 stainless steel. That's why this type of stainless steel is called eighteen-eighths stainless steel in this industry. In fact, related product standard has very clear rules to 304, which is different to stainless steel of different shapes.
