The product is the round component in the center of the image. The lower three-fifths of the vertical section is shaped into four blades, with their tips evenly and tightly pressed together.

To ensure the four blade tips are securely in contact, various techniques are applied, such as surface pressing around the blades and shaping them into a perfect circular form. The biggest challenge in the curling process is preventing twisting and eccentricity, as the connecting section to the carrier is only 0.3 mm wide and the pre-curling developed length is just 3 mm.

If you are facing difficulties with precision curling processing, please feel free to contact us.
