Press selection
For hot forging aluminum, forging machines such as screw presses, crank presses, hydraulic presses, and hammers are used.
The forging machine to choose depends on the forming process, the work piece (geometry and material), and quantities to be produced. The machine selection also depends on the potential degree of automation as well as on economic features. The machines’ types can be classified as energy-related machines (screw presses, hydraulic double-acting hammers), course-related machines (crank presses), and force-related machines (hydraulic presses).
Hydraulic presses can be controlled very well in terms of force and speed, so they are suitable for pre-forming or open die forging due to their high flexibility.
Also, due to their high flexibility, hammers can be adapted to different working conditions. They are the least expensive forming machines; however, they can produce excessive noise and shock, which affects working conditions.
Mechanical presses are course-related machines that can generate only a certain forming energy via a defined course and thus with a limited force. The following presentation will be limited to mechanical and hydraulic presses only.

按选择为热的锻件铝, 锻件机器譬如螺丝新闻, 曲柄新闻, 水力新闻, 并且锤子被使用。锻件机器选择取决于形成的过程、工作片断(几何和材料), 和数量被生产。机器选择并且取决于潜在的程度自动化并且在经济特点。机器的类型可能被分类作为相关能源机器(螺丝新闻, 水力double-acting 锤子), 与路线相关的机器(曲柄新闻), 和与力量相关的机器(水力新闻) 。水力新闻可能被控制很好根据力量和速度, 因此他们是适当的为pre-forming 或打开模子伪造由于他们的高灵活性。并且, 由于他们的高灵活性, 锤子能适应不同的工作环境。他们是最少昂贵的形成的机器; 但是, 他们能导致过份噪声和震动, 影响工作环境。机械新闻是可能引起唯一有些形成的能量通过一条被定义的路线和因而用有限的力量的与路线相关的机器。以下介绍对机械和水力新闻将被限制唯一。
