When dealing with sheet metal fabrication, your two major options will usually be either laser cutting or stamping. Laser cutting has some significant advantages over traditional sheet metal stamping, even though sheet metal stamping is generally less expensive.
1. Laser Cutting Is More Precise
When stamping there isn't always a complete uniformity. Not only will the stamps change slightly over time (the first run metal will be different from the last run metal), but there will also be some natural deformity in the stamping process.
