Spring Properties
Aoi Spring uses wire forming machines to bend wires into a variety of shapes.
Compared to springs pressed with a stamping die, wire formed springs offer the following advantages:
1. No upfront investment. (However, there are special cases when costs for jigs and other tools may arise.)
2. You can change designs quickly.
3. Less material loss means wire forming is the best way to cut costs.
Aoi Spring can fulfill your requests with our vast array of wire forming machines.
