Roll Bending Machines Work Principle

The effect of the strip shape defects is due to the fact that the strips have different internal stresses in the width direction, resulting in a small length difference in length along the longitudinal fibers adjacent to each other in the width direction. In order to obtain a flat plate strip, it is only necessary

Aluminum Profile Stretch Elongation

The calculation of elongation T (sheet thickness) = r (outside) – r (inside) ð (elongation rate) = t / r (inside) ×100% The national production standard for Aluminum profile(6063、T5)is ð (elongation rate) ≥ 8 % The general elongation rate requirements in Aluminum profile stretching Aluminum profile(6063, T5): When the bending ð (elongation rate) ≤ 10
