What is Closed die forging?
The closed die forging is a metal forming process that compresses a piece of metal under high pressure to fill an enclosed die impression. For some special shapes, the second forging operation is required to reach the final shapes and dimensions.
What is Open die forging?
Open die forging is the process of striking a hammer to deform a piece of metal, typically placed on a stationary anvil. Another approach is to use compression to press the metal between the simple dies.
Difference between the open die and closed die forging:
- Open die forging is the workpiece is compressed between the two flat dies, while the closed die forging the workpiece is compressed between the two impressed dies.
- Open die forging the cost of dies is low, while the closed die forging the cost of dies is high.
- The process is simple in Open die forging, while the closed die forging process is complex.
- Open die forging machining of components is required, while the closed die forging, machining of the component are not required.
- Open die forging there is poor utilization of the material, while the closed die forging there is a better utilization of the materials.
- Open dies forging the dimensional accuracy of the obtained products is not good, while the closed die forging the dimensional accuracy of the obtained products is good.
- Open die forging is used for low-quality production, while closed die forging is used for high-quality production.
- Open die forging is suitable only for the production of the simple type of components, while closed die forging is suitable for the production of simple and complex components.
