自由锻造是靠人工操作来控制锻件的形状和尺寸的，所以锻件精度低，加工余量大，圣霖国际锻造生产，劳动强度大，生产率也不高，因此它主要应用于单件、小批量生产。
Free forging is by manual operation to the shape and size of the forgings，圣霖国际锻造价格， so the precision of the forgings is low， the processing allowance is large， the labor intensity is big， and the productivity is not high. Therefore， it is mainly used in single piece and **all batch production.
自由锻的基本工序主要有镦粗、拔长、冲孔、切割、弯曲、扭转、错移及锻接等。模锻又分为开式模锻和闭式模锻．金属坯料在具有一定形状的锻模膛内受压变形而获得锻件，模锻一般用于生产重量不大、批量较大的零件。
The basic process of free forging are upsetting， stretching，圣霖国际锻造， punching， cutting， bending， torsion，圣霖国际锻造报价， displacement and welding etc.. Die forging is also divided into open die forging and closed die forging. Metal billets are pressed and deformed to form forgings in the forging die chamber with a certain shape， and die forging is generally used for producing parts with **all weight and large batches.
锻件是金属被施加压力，通过塑性变形塑造要求的形状或合适的压缩力的物件。这种力量典型的通过使用铁锤或压力来实现。锻件过程建造了精致的颗粒结构，并改进了金属的物理属性。
A forged piece is an object that is applied to the metal by pressure to shape the required shape or the appropriate compression force by plastic deformation. This force is typically achieved by using a hammer or pressure. The process of forging has built a fine particle structure and improved the physical properties of the metal.
