On December 19th, the 2009 LED Industry Investment and Market Strategy Forum was successfully concluded in Shenzhen Golden Central Hotel. The forum was hosted by the well-known domestic industry research, media organization Gaogong LED and National High-tech Enterprise Development LED Professional Committee. This forum invites Chen Yingchun, deputy mayor of Shenzhen, and Gao Lin, deputy director of LED project of Shenzhen Science, Industry and Trade Committee, and many LED industry experts, including Xiao Kewei, managing director of Jingke Electronics, Li Mantie, general manager of Lehman Optoelectronics, CTI Nie Pengxiang, vice president of China Testing and Testing Institute, Gu Yongde, chairman of Maoshuo Power, and Xiong Yingxiang, general manager of Deshida Optoelectronics. At the same time, many investors and institutional leaders attended and delivered speeches.
The topics of this forum are mainly focused on LED investment opportunities and risks, market development and how to finance. The content includes all aspects of the LED market and investment. Such as the traditional lighting to fight semiconductor lighting, the analysis of the success or failure of the company's listing report, the current status and strategy of the global LED market, order-for-investment: the fog of the lost LED industry.
What is the status of the LED industry market? Liu Zhen, general manager of Shenzhen Quantum Optoelectronics Co., Ltd. believes that the effectiveness of the six national policies and the lack of success after the government's investment, how to support the market to continue to prosper into a difficult problem.
Liu Zhen said that more than one hundred cities in 18 provinces in China have regarded the solar crystal silicon project as the “top-ranking projectâ€, which echoes the fact that more than one hundred cities have monopolized the local LED public lighting as a bargaining chip. . In this way, the national LED industry standards and product standards will not be implemented. Local governments are stepping up the development of local LED standards. It is difficult for domestic LED companies to make a fuss about domestic demand.
Liu Zhen emphasized that a small number of enterprises have used the quick success of local governments to install various LED products with quality defects and carry out unfair price wars, which directly led to the emergence of “bad money to drive out good moneyâ€. The large-scale expansion of LED chip packaging companies in 2009-2010 has made it possible for the bust of excess capacity in 2008 to reappear.

The single groove blanking process of motor blanking is a kind of blanking process relative to double blanking. Motor fixed, Rotor Core punching using single groove punching process, its mold design, manufacturing are relatively simple, suitable for small batch, variety of production, has the characteristics of low cost, fast change. With the development of advanced punching machine, production efficiency continues to improve, the single punching process is also developing rapidly. For the large motor, because of the cost of the duplex die and the equipment capacity, the single groove is also used. Another advantage of single groove punching is the consistency of groove size. Compound die is the same punch, stator or rotor groove completed at one time. How many slots correspond to the same number of punches, punch size to achieve complete has always been some difficulties: single slot punching is by the same punch to complete all the slots, groove consistency is better.
Stator and rotor laminations are an important part of motors and generators. For large-size and small-batch punching sheets, we usually use the notching method to produce them. The advantages of notching are that the cost of the notching die is low and the production cycle of the notching die is short. It is suitable for producing large size laminations, usually the outer diameter is from 500mm-1250mm. The slot size is more accurate than Laser Cutting.
