Blanking
The Blanking machine 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.
Manufacture of the blanking tooling and of blanked parts can be designed
and ordered separately. After tooling costs, blanking has low production cost.
Possible shapes
Any 2D shape.

Example parts
Brackets, enclosures, assorted mechanisms.
Advantages of Blanking
Low cost when the quantity is moderate
to high (typ. 1000+).
Specifications for Blanking
 Material - most
sheet metal. Hard plastics are possible but can present difficulties.
Alternative machines
- Turret Punch (for moderate quantity), Laser Cut (for low quantity), Mill 3-Axis (for
very low quantity).
