Other ways to produce multi-gauge strip material are rolling or forging. However, producers of electrical connectors or leadframes for discrete semiconductors appreciate the milling technique because of a number of reasons:

• Hardly any limits for the cross section, including multiple channels.
• Prevention of internal stresses because the strip is not deformed during contouring.
• Low tool costs. This is important for small production lots and a quick karket launch of new products.

Advantages of milling

• Milling does not produce any stresses and allows dimensionally accurate transitions between thick and thin sections. The tooling costs are low.

Advantages when stamping contour-milled strip

• Less coining or folding, requiring simpler tools; strip consumption per stamped part is reduced.
• Simpler stamping tools, resulting in reduced costs for new tools and maintenance.
• Lower stamping force, higher stamping speed.
