自由锻造分手工自由锻和机器自由锻。手工自由锻生产效率低，劳动强度大，forging报价，仅用于修配或简单、小型、小批锻件的生产。

Manual free forging is inefficient and labor intensive. It is only used for the production of repair or simple， *all and *all forgings.Free forging c*ists of manual free forging and machine free forging.

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，forging生产厂家，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.

铝合金锻件的生产可在多种锻造设备上进行。锻锤可用于开式模锻和闭式模锻，其生产费用较低，forging哪家好，锻打时需要控制好锤头的高度、打击力量和速度，因为在急剧变形过程中铝合金对应变速率敏感并具有放热性。机械压力机和螺旋压力机都广泛用于铝合金闭式模锻，适宜于生产中等尺寸、大体积和形状适度的铝锻件。

The production aluminum alloy forgings can be carried out on a variety of forging equipment. Hammer can be used for open die forging and closed die forging， the production cost is low，forging， when the need to the forging hammer height， strike force and speed， because of the sharp deformation in the process Alloy strain rate sensitive and exothermic. Mechanical press and screw press are widely used in aluminum alloy closed die forging， which is suitable for the production of medium size， large volume and moderate shape aluminum forgings.
