These zigzag springs are made piece by piece but not in rolls, the 2 ends are made to a custom design. First let’s take a look at how it is made on a CNC bending machine. The video is quite straightforward so you can easily understand the process.

  • Material C70 (carbon steel)
  • Wire diameter 3.0 mm
  • Dimension (relaxed) length 80 * width 60 mm
  • Surface coating None
  • heat treatment 230℃, 30 minutes

As you may notice, the 2 ends are bent to a custom design, that is why they need to be bent on a CNC machine.
