Since the 1980s, in the national plastic base industry policy and supporting a series of national economic policy support and guidance, China's plastic base industry is developing rapidly, the average annual growth rate of 13%, 1999 China's mold industry output value To 24.5 billion in 2000 to 27 billion yuan, of which about 30% of plastic mold. In the future mold market, the proportion of plastic mold in the total mold will gradually increase.
China's plastic base industry from the start to the present, after more than half a century, with great development, mold level has been greatly improved.
Molding process, multi-material plastic molding mold, high-efficiency multi-color injection mold, inlay interchange structure and core pulling mechanism of the innovative design also made great progress. Gas-assisted injection molding technology is more mature, such as Qingdao Hisense Mold Co., Ltd., Tianjin Communications Broadcasting Company Mold Factory and other manufacturers successfully in the 29 to 34-inch TV shell and some thick-walled parts of the mold using gas-assisted technology, some Manufacturers also use the C-MOLD gas-assisted software, to achieve better results.
In the manufacturing technology, CAD / CAM / CAE technology on the application level to a new level to produce household appliances as the representative of enterprises, have introduced a considerable number of CAD / CAM systems, such as the United States EDS UG Ⅱ, the United States Parametric Technology Pro / Emgineer, CVS5 from CV, UK DOCT5 from Deltacam, CRADE from HZS, Cimatron of Israel, C-Mold of AC-Tech in USA and MPAS Mold Analysis Software of Moldflow Company in Australia. The introduction of these systems and software, although spent a lot of money, but in China's mold industry, the realization of the CAD / CAM integration, and can support CAE technology on the molding process, such as filling and cooling computer simulation, made a certain The technical and economic benefits, and promote and promote the development of China's mold CAD / CAM technology.
