Bending Specifications

Bending Specifications

Normal Bending

No.	Standard Part	Standard Value	Example
1	Bend angle tolerance	Product lineup: Standard / International Economy Plate Thickness ≤ 10.0 mm: ±1.0° Plate Thickness > 10.0 mm: ±1.5°
2	Inner radius (r)	Plate thickness (reference value)
3	Outer radius (R)	R = plate thickness × 2 (reference value)

R-bend shape(FR bending)

No.	Standard Part	Standard Value	Example
1	Bend angle tolerance	±2.0°
2	Inner R	Modeling dimension (Reference value)
3	Outer R	Inner R+Plate thickness (Reference value)

Protrusions from Bending

Standard Value	Example
As shown in the right hand example, bulging/protrusions of about 15% of the plate thickness can occur on each side.

Defects Caused by Bending

Standard Value

Example

As shown in the right hand example, defects have occurred in the bent die.

Since it is processed as FR bending (feed bending), die marks will be left on the R bending part.

■Without surface treatment (EN AW−5052 equiv.)
Inner bend	Outer bend

■Paint
Inner bend	Outer bend

Cracks caused by bending (EN AW−5052 equiv.)

Standard Value	Example
EN AW−5052 equiv. would have a slight crack when bent due to its material properties.	■EN AW−5052 equiv. (Thickness: 6.0 mm)
