第一节概述压力铸造是近代金属加工工艺中发展较快的一种少无切削的特种铸造方法,具有生产效率高、经济指标优良、铸件尺寸精度高和互换性好等特点,在制造业,尤其是规模化产业得到了广泛应用和迅速发展。压力铸造是铝、镁和锌等轻金属的主要成形方法,适用于生产大型复杂薄壁壳体零件。压铸件已成为汽车、运动器材、电子和航空航天等领域产品的重要组成部
The first section outlines the pressure casting is a modern metal processing technology in the development of a less non-cutting special casting method, with high production efficiency, excellent economic indicators, casting size and high precision and interchangeability characteristics, in the manufacturing , Especially large-scale industry has been widely used and rapid development. Pressure casting is a major method of forming light metals such as aluminum, magnesium and zinc for the production of large and complex thin-walled shell parts. Die casting has become an important part of the products in the fields of automobiles, sports equipment, electronics and aerospace
