Free forging

Refers to a method of forging a simple universal tool or directly applying external force between the upper and lower anvils of the forging equipment to deform the blank to obtain the required geometry and internal quality. Forgings produced by the free forging method are called free forgings.

Free forging is mainly based on forgings with small production batches. Forging equipment such as hammers and hydraulic presses are used to shape the blanks to obtain qualified forgings. The basic processes of free forging include upsetting, drawing, punching, cutting, bending, twisting, shifting and forging. Free forging adopts hot forging method. For example, national standard shackle, Japanese style shackle , European style shackle, etc.


2.Die forging

Die forging is divided into open die forging and closed die forging. Metal blanks are deformed by compression in a forging die cavity with a certain shape to obtain forgings. Die forging is generally used to produce parts with small weight and large quantities. Die forging can be divided into hot die forging, warm forging and cold forging. Warm forging and cold forging are the future development direction of die forging, and they also represent the level of forging technology. Such as cargo hooks, lifting rings, rotating rings, double ring buckles, American die forged flower orchids, strong rings and so on.


3. Grinding the ring

Ring milling refers to the production of ring-shaped parts with different diameters by special equipment ring milling machines, which are also used to produce wheel-shaped parts.


4. Special forging

Special forging includes forging methods such as roll forging, cross wedge rolling, radial forging, and liquid die forging. These methods are more suitable for producing some special shaped parts. 后续的成形压力;楔横轧可以生产钢球、传动轴等零件;径向锻造则可以生产大型的炮筒、台 阶轴等锻件。 For example, roll forging can be used as an effective preforming process to greatly reduce the subsequent forming pressure; cross wedge rolling can produce steel balls, transmission shafts and other parts; radial forging can produce large forgings such as barrels and step shafts.
