工艺简介：自由锻造是利用冲击力或压力使金属在上下砧面间各个方向自由变形，不受任何限制而获得所需形状及尺寸和一定机械性能的锻件的一种加工方法，要求操作者具备较为熟练的操作经验。

工艺应用：自由锻是一种比较传统的锻造工艺，通常用于锻打形状较为简单的产品，例如棒条、粗胚、圆环、轴等。

The Open Die Forging Process：Open Die Forging is one of the oldest forms of manufacturing, using traditional blacksmith methods. The billet is heated above recrystallization temperature,ranging from 1000°C to 1300°C for steel, and gradually shaped by skilful hammering or pressing of the work piece to create the desired shape.

Application: Open Die Forging is an old manufacturing process often associated with simplershaped parts, such as bars, blanks, rings, hollows or spindles, it can beconsidered the ultimate option in custom-designed metal components.
