China’s mold industry has experienced rapid development in recent years, and the achievements have been considerable, especially since the beginning of the year, under the guidance of the national twelfth five year plan, the industry vigorously develops high-end precision equipment, and constantly promotes the steady progress of China’s mold industry.
According to experts, due to the development of die and mold industry in recent years to a larger, more precise, more complex and more economic and rapid direction, so the requirements for the miniaturization and precision of its products are higher, which urges China’s mold industry to constantly improve and upgrade technology to adapt to the changing market environment. According to relevant data, in terms of precision plastic mold, China has been able to produce plastic parts mold for camera and mobile phone, multi cavity small module gear mold and 7800 cavity plastic sealing mold with accuracy of 5 μ M.
In recent years, domestic die steel production has made great progress. At present, many domestic steel mills are mass producing some steel grades with strong universality or excellent performance internationally, such as 4Cr5MoSiV1 (equivalent to aisih13), 3Cr2Mo (equivalent to aisip20), 10ni3mncaal, Cr12MolV1 (equivalent to aisid2), etc. Among them, 4Cr5MoSiV1 and 3Cr2Mo are relatively large in production and use, and their research and improvement are also in-depth.
Reducing material cost and improving performance price ratio have become the focus of new die steel development in advanced die steel production enterprises. For example, when Hitachi Metal Co., Ltd. and Datong Special Steel Co., Ltd. introduced their products at the technical exchange meeting during the exhibition, they all agreed to develop dac-magic hot working die steel, hpm-magic and cena1 plastic mold steel and dha-world die-casting die steel to cope with the financial crisis and more fierce market competition.
Generally speaking, some well-known die steel manufacturers abroad still have obvious advantages in the production means, variety specifications, serialization degree, after-sales service and awareness and effect of developing new steel grades. CNC machine tool processing of domestic die steel serialization degree and quality stability is still to be improved; the proportion of production and application of some good performance die steel is still low, the application of most new steel is still small, at the same time, there is a lack of effective means of promotion and sales, post-sale service needs to be improved; in addition, some new steel grades with special performance need to be developed. Improving and perfecting the above shortcomings will still be the main task of die steel development in China in the future.
