Model WF325 -Stainless Steel Small Double Torsion Spring

SHARE

These are 2 small double torsion springs made of stailess steel 304. The first spring (the one on the right) is easier, while the second spring (the one on the left) is a lot harder to be made because there are a lot of right angle bendings, and these bendings are made in a small space. We spent almost 2 days to programme the machine.

  • Material SS304
  • Wire diameter 1 mm
  • Dimension (relaxed) 18*20 mm
  • Surface coating electro polishing
  • heat treatment 230℃, 30 minutes
