Mold the direction of rapid manufacturing technology

Want, with the prerequisite of the requirements is its rapidity, that is, from design to market time as short as possible. This is the RT technology and high-speed cutting technology the root causes. Discrete / RT deposition modeling technology based on the principle of net removal of material forming the high-speed cutting technology the two are complementary,[link widoczny dla zalogowanych], have been the type of CNC technology support. RT technology can be said to be truly digital manufacturing, as RT technology not only support tool trajectory control, and can be directly related to the material itself, which can perform more complex shape processing, can also create a functionally graded material gradient of the mold, But it is the forming principle, limiting its current accuracy and surface roughness. In contrast, although the high-speed CNC machining technology is the digital analog processing, only the same kinds of materials, machining, but in terms of accuracy and surface roughness control can not be compared with the advantages of RT technology, many companies use their respective advantages and die, At the same time using both technologies. Can be expected, Mould & dieproject2005.

Laiwu Steel molds previously used only to die in the module manufacture, market price is not high, profit margins smaller, less competitive. The R & D by the Laiwu Steel Technology Center, also known as P20 rolling rolling mill 3Cr2Mo, mainly used in the manufacture of plastic molds, are high-tech, high value-added products, the market price is high and in short supply, the demand in ten years tons. As the steel on steel demanding, Laiwu Steel Technology Center has developed a detailed plan and process quality trial operation points, thus ensuring a product quality inspection. Japan will transfer abroad of mold manufacturing mold industry in Japan after 1998, output value of 1.87 trillion yen, after the peak,[link widoczny dla zalogowanych], although the growth rate slowed for several years, but still has growth, but since 2004 there has been recovery. Japan remains the world leader in mold technology. Slowdown in the mold industry in Japan is mainly caused by the transfer to other countries, rather than technical problems. Mold industry in Japan to China,[link widoczny dla zalogowanych], Southeast Asia and other countries the shift. Japan's mold production accounts for about 40% of the world, ranking first in the world every year die from abroad for a large number of 1:3. Die increasingly competitive market, the Japanese die industry has to reduce production costs. Japanese industry is now gradually die is not high-tech transfer out of the mold parts, only the indigenous production of high-tech products; major companies in Japan use the mold to speed up the transfer abroad of the trend, with prices lower middle and low mold the mold, but also accelerated the pace of overseas development of mold manufacturers. ■
