Bend To Mold Line Distance Calculation

Bend To Mold Sheet Metal Line Distance Calculator determines the bend line to mold allowance when forming sheet metal.


Inside Bend Radius (R) (Inches) :
Thickness (T) (inches) :
Angle(a) Must be > 90 and < 180 degrees :




Distance to Mold Line (D):

Most sheet metal materials will conform to the calculations.

Bend radius

Bend radius is measured to the inside curvature, the bend radius is the minimum radius one can bend a pipe, tube, sheet, cable or hose without kinking it, damaging it, or shortening its life. Smaller bend radius means greater is the material flexibility, when the radius of curvature decreases, the curvature increases.
