The forging process usually includes the following steps:
1. **Material selection**: Select metal materials suitable for forging, such as carbon steel, alloy steel, etc.
2. **Heating**: Heat the metal material to a certain temperature to make it soft and easy to forge.
3. **Forging**: Use a forging machine or hand forging tools to shape the metal to form the required bow shackle shape.
4. **Cooling**: After forging, the metal piece is cooled to fix the shape.
5. **Heat treatment**: Heat treatment such as quenching and tempering may be required to improve the hardness and toughness of the shackle.
6. **Inspection and testing**: The forged shackle is inspected for quality and tested for load capacity to ensure that it meets the requirements for use.
