Beijing North Hengli Science and Technology Development Co., Ltd. by the Chinese Academy of weapons, weapons technology to promote China jointly founded the high-tech enterprises. Companies to promote the progress of the design and the traditional casting industry, accelerate scientific and technological achievements into the goal, the use of powerful technological advantages successfully developed a series of domestic initiative, high technology content, good market prospects of high-tech products, and the fastest speed products to market. In China, from the mid-1990s to the SLS technology research, in 2000 he developed the first localization of SLS rapid prototyping equipment and industrial transformation. Hani -500 rapid prototyping machine, selective sintering rapid prototyping technology, can make any complex three-dimensional CAD model using a laser beam or other means to direct the processing of materials or parts solid model, it can quickly create any complex parts. Forming range, low cost, high utilization without waste. And a three-speed steel molding technology. You can quickly create any complex parts, shorten new product development cycle and reduce development measure very sad this, and no cutting noiseless, green production process, improve the competitiveness of enterprises. In addition, the Chinese Academy of Sciences as well as weapons Hengli independently developed casting simulation software castsoft, effective forecast shows the flow field temperature field simulation of the casting process, which interrupted him, details of the consultation Liu 18,233,177,200
