Flattening Punch vs. Standard Punch
A standard press brake punch is primarily designed to form an angle.
A Flattening Press Brake Punch has a different purpose: it is designed to compress and flatten an already formed sheet edge.
That difference is reflected directly in the tool geometry. The elongated narrow profile is not simply a decorative shape—it is intended to provide access, clearance and controlled force transmission during the flattening stage.
For this reason, flattening tooling should be selected according to the pre-bend geometry, material thickness, hem size, required final profile and available machine/tooling interface, rather than selecting it only according to the punch angle.
