lend support to the high-tech aviation and space industries. Te aviation equipment manufacturing industry es expected to gain more market share (20-30%), so it may receive more policy support in the future.


7. Power Generation According to China’s 11th five-year plan, the goals of


large technical equipment have been achieved, and the producers’ ability to guarantee the equipment also has been significantly strengthened. It is believed that the need for efficient and clean power-generating equipment can be met by domestic enterprises and that their technical level and product quality are world-class. Te domestic producers are now providing 1,000-kV extra high voltage electric trans- mission and transformation equipment (more than 90% of use) and ±800-kV direct current transportation (more than 60%). China was the first country to begin using extra high voltage electric transmission and transformation equipment. As the engine industry and electric equipment industry develop, increased demands for the die manufacturing industry will arise.


8. Hot Stamping Die Hot stamping is a new material processing technology in


which steel plates are heated to over 900C, stamped rapidly, and cooled off at a constant pressure to realize the quench strengthening of hot stamping die steel. Because hot stamp- ing can help reduce the weight of a motor car while reducing carbon discharge, it has the advantages of a short adjustment cycle, long service life (200-300,000 strokes), interchangeabil- ity of hot glutting and low cost. China has 110 hot stamping stream lines, and it’s predicted that the need for hot stamping parts will be 350 million. If the output of one stream line is 1.5 million, the number of hot stamping stream lines will be doubled. In addition, hot stamping technology can be used in the agricultural and mining machinery industries. Te two major hot stamping equipment suppliers, Schuler


of Germany and APT Co. of Sweden, have set up branches in Shanghai. Te three major hot stamping parts suppliers, Bentler of Germany, Gestamp of Spain, and Magna (Cosma International) of Canada, have set up hot stamping stream lines in Changchun, Kunshan and Shanghai. Although 40% of the parts used by large companies such as Volvo are hot stamped, few companies have mastered the development of hot stamping dies. A hot stamping stream line launched by Baosteel was


produced by the Ningbo Heli die company. Hot stamping dies in the domestic market are almost always imported (one set of ordinary B hot stamping die costs more than 4 million yuan). Ningbo Heli has taken the leading position in lot manufacturing of hot stamping dies, and in the future, it will supply appliance dies for the hot stamping stream lines of Saikeli, Lingyun, Changchun Beite, Changan Xingqiao, Chongqing Dajiang, FAW, Tianjin Yuao, Shanghai Hui- zhong and Wuxi Qihao. ■

基本满足国内需求，技术水平和产品产量已经进入世界 前列。1000KV特高压交流输变电设备和±800KV直流 输电成套设备综合自主化率分别达到90%以上和60%以 上，我国成为世界上首个特高压输变电设备投入工业化 运行的国家。随着发动机和电力设备行业的不断发展， 对其模具制造设备也提出了更高要求。


8热冲压模具市场


热冲压是20世纪80年代发明的一种把钢板加热到 900℃以上，快速冲压，然后保压冷却，通过内部通冷 却水的热冲压模具实现淬火强化，从而制作超高强度零 件的新型成型技术。由于热冲压技术能实现汽车车身轻 量化，减少碳排放，热冲压模具调试周期短，使用寿命 在20~30万个冲程，热作镶块具互换性，制造成本低， 在汽车领域获得越来越广泛的应用。目前全球有110条 热冲压线，预计到2013年，热冲压零件的年需求量是 3.5亿个，按照每条生产线150万件的年产能计算，届 时热冲压生产线数量将翻一番。另外，热冲压技术在农 业、矿山机械领域也有广泛应用。


目前，全球两大热冲压装备供应商，德国的Schuler 和瑞典的APT公司上海建立分公司。全球三大热冲压 零件供应商，德国Bentler、西班牙Gestamp、加拿大 Magna(Cosma)公司分别在长春、昆山、上海建立了热 冲压生产线。尽管国外像VOLVO等大厂家使用热冲压 件的比例已经高达40％，但全球掌握热冲压模具开发的 公司很少，中国本土宝钢已经投产的热冲压件生产线模 具是由宁波合力模具公司开发成功的。国内热冲压模具 基本依赖进口（一套普通B柱热冲压进口模具价格400 万元以上），宁波合力在批量热冲压模具制造领域处于 领先地位，未来将为赛科利、凌云、长春北特、长安星 乔、重庆大江、一汽、天津顺达、天津宇傲、上海汇 众、无锡奇昊等公司热冲压生产线提供配套模具。


9出口市场


我国出口的压铸模具目前集中在欧洲、北美、日本、 韩国等地，部分企业的出口模具量已占总产值30%以 上。越来越多的优质压铸模飘洋过海，这些模具共同特 点是用料考究、制作精良、尺寸精度高、符合客户标准 要求、使用寿命和铸件质量达到国际先进水平，同时具 有明显的价格优势。我国压铸模具不但把国内顶级的客 户吸引过来，而且吸引了北美通用、美国克莱斯勒等世 界级汽车巨头眼光，他们已经多次派专家来内地公司考 察，大家彼此都有合作的意向。我国模具出口到欧洲的 汽车油底盘压铸模由于价格优势强、设计先进、制作精 湛得到外商认可，一再追加订单。 ■
