一、适应技术革新 日本的精密铸造技术在第二次世界大战后才得到开发,历史很短。然而,随着机械工业的发展对精密铸件在尺寸精度、形状复杂程度、外观和内部组织等方面,提出了更高的要求。1965年前后,从欧美精铸企业引进了这种技术,并以此为基础逐步加快了技术进步。 现在,一般机械部件占精密市场的主流。近期,精铸行业在与其他毛坯加工行业的竞争中,一部分已开始进入尖端技术行业。 精铸行业的市场,可以说是宇航、核能、汽车工业、通信设备以及有关医疗行业等五大领域。本文叙述的是过去的市场变化和今后的
First, to adapt to technological innovation Japan’s precision casting technology was developed after the Second World War, history is very short. However, with the development of machinery industry, precision castings have higher requirements in terms of dimensional accuracy, shape complexity, appearance and internal organization. Around 1965, this technology was introduced from the foundry companies in Europe and the United States, and based on this technology, technological progress was gradually accelerated. Now, the general mechanical parts of the mainstream of the precision market. Recently, the casting industry in competition with other rough machining industry, some have begun to enter the cutting-edge technology industries. Casting industry market, can be said that the aerospace, nuclear energy, automobile industry, communications equipment and the medical industry and other five major areas. This article describes the past changes in the market and the future
