Achieving True Zero-Radius Flattening Bending
The design of the Hemming Die demands exceptional precision, particularly in the lower flattening bending surface. Perfect parallelism and rigid tool alignment between the upper punch and the die are critical. This ensures the material is compressed uniformly, achieving a true zero-radius hem without any material bunching or uneven deformation along the bend line, which is the hallmark of professional Press Brake Tooling.
