With the development of science and technology, and social needs of the diverse, more competitive products, replacement cycle is getting shorter. The requirement of not only the requirements of the market as soon as possible to design new products, but also in the shortest possible time to produce prototypes to conduct performance testing and modification of the final forming shape products. In traditional manufacturing systems, requires a lot of mold design, manufacture and commissioning work, high cost, long period, can not meet the rapid changes in the market. In order to improve R & D and production speed, quickly and accurately to produce high-quality, low-cost molds and products, can make quick response to market changes, people made a lot of research and exploration work. With the falling prices of industrial lasers and industrial laser processing technologies become more sophisticated, to mold manufacturing and product production process has brought significant changes. This paper introduces the industrial processing lasers, and laser in mold making, mold surface laser hardening and alternative, laser die repair, mold and other aspects of laser cleaning are introduced and analyzed.

Industrial processing lasers Present, industrial lasers used in laser processing are two major categories: solid-state lasers and gas lasers. Among them, solid-state laser with Nd: YAG laser as the representative; and gas lasers CO 2 Laser as the representative. With laser technology, now people are starting to use some processing power applications high-power fiber lasers and semiconductor lasers.

HC Chemical Network News, the mother of an industrial chemical called, but the chemical industry’s contribution and impact on the environment and security, they often make people tough love and hate the cut. Yesterday, the province held special rectification of chemical manufacturers teleconference meeting, the City related to lead in the final speech, announced that this meeting marks a new round of chemical manufacturers special work started.

“Globe Solar Power Chinese, the Chinese solar power in Shandong. “This is the solar energy market rumors say. As the most concentrated solar thermal organization in the province?? Shandong Province, China Solar Thermal Industry contradictions and issues that exist have been embodied in Shandong. Recently, on Solar Thermal Business Status investigated.

6,000 companies in an business in chaos

“According to incomplete statistics, concentrated solar thermal market, about 6,000 significant and modest enterprises, can be mentioned that the business is now extremely fragmented business. Messy, quite a mixed bag, disorder and even vicious competition.” Sept. two Day, when it comes to solar thermal market currently faces difficulties, as the line in Shandong, 1 of the leading new force Norit Energy Co., Ltd. Deputy Common Manager of light consistently on Literature and Philosophy, sigh.

According to him, solar thermal industry is in the country is a nascent market, China Solar Thermal Market in now Sell Revenue of about in between 40 billion? 50 billion yuan between, the sales volume and not even a enterprise in Shandong Haier 1 / 3, but is in this modest market, but gathered more than 6,000 businesses nationwide, so several organizations divided four to 5 billion business output, industry fiercely competitive, is evident. “Now for each and every business enterprise, and are in a very precarious, unstable position in the marketplace.”
