Stationary tool in metal plate bending machines that shapes metal against the upper punch.
The lower tool, commonly called a die, is a precision-engineered stationary component in metal plate bending machines that provides the forming surface against which the metal plate is pressed by the upper punch. It determines the final bend angle, radius, and geometry of the workpiece through controlled deformation.

V-dies create sharp bends with defined angles (typically 30°-90°), while U-dies produce rounded bends with larger radii, suitable for thicker materials or specific geometries.
Die opening is typically 6-8 times the material thickness for mild steel. For example, a 3 mm plate requires an 18-24 mm V-opening. Consult machine manufacturer guidelines for specific materials.
