High Pressure Die Casting (HPDC) is when molten metal is forced at high speed and high pressure into the cavity of a closed die. The die is locked tightly in place by powerful closing forces applied by the horizontal HPDC machine used. Once the metal has solidified, the die is released, and the casting is ejected.

The forces applied to the die are critical to achieving a tight seal and casting precision. The bigger the part, the greater the pressure needed to guarantee accurate die closure.
With large ‘single piece’ castings increasingly popular - especially in automotive - HPDC machines able to deliver massive closing forces are often preferable.
Our Giant HPDC machines deliver closing forces up to 11,000 tonnes!
高压压铸工艺是如何工作的？
高压压铸技术可以生产非常大的轻合金零件，大批量，速度快。
这些设备可提供具有高精度、卓越的表面光洁度、出色的均匀性和最佳的机械性能的轻合金零件。
高压压铸工艺还可以生产具有薄壁的组件和具有不同类型插件的“共铸”零件，例如螺钉和衬垫，这些之后成为产品本身的组成部分。
Do I need a Toggle Free HPDC machine?
That depends. As the name suggests, Toggle Free HPDC machines have no toggle.
Because of this, they typically have a smaller machine footprint, greater rigidity and fewer wear parts for improved reliability and lower maintenance costs, they tend to be a preferable choice where closing forces of more than 1,650 tonnes are required.
应用
冷室高压压铸技术是生产各种铝和镁汽车铸件的理想选择，如发动机缸体、变速箱壳体、油槽、发动机支座和跨车梁等结构件。
它广泛用于其他领域，用于生产从最简单（照明组件）到最苛刻（如航空发动机零件）应用中的各种组件。
