Blanking is a process that creates shapes in sheet material by applying a punch and die, custom designed to the shape of your design. Blanking forces the custom punch tool through the sheet and into a mating die. A key advantage of blanking is its low cost when the quantity is moderate to high (typ. 1000+).

Blanking can create almost any 2D shape. The process can be applied to most sheet metals. Blanking requires a custom punch and die which adds to initial cost but results in low production costs.

Blanking Cost Reduction Tips

• Use rounded corners and shapes.
• Try to design shapes with no interior holes or cutouts.
• Minimize the size of the part.

Blanking design considerations

• Edges will have a slight rounding on the top side
• Edges will have a slight burr on the bottom side.
  
• The bottom side may have a few thousandths more material than the top side.
