Abstract: An springback compensation method for on-line real-time metal sheet roll bending includes the steps of using multiple rollers to bend a continuous metal sheet of multiple sections having different materials or different thickness respectively; using a first position sensor to individually measure springback angles of the multiple sections of the bent metal sheet, and feeding back to a programmable logic controller; using the programmable controller to control a bending roller to compensate the multiple sections of the bent metal sheet respectively; using a second position sensor to individually measure compensated angles of the multiple sections of the bent metal sheet; and comparing a difference between the compensated angles and standard angles of the multiple sections of the bent metal sheet after compensating bending.

Abstract: A method for manufacturing a clad type electromagnetic shielding material includes step as follows: a first electrically conductive metallic layer, a magnetically conductive metallic layer, a second electrically conductive metallic layer and a shock-absorbing insulation layer, which are stacked in order, are one-time continuously rolled by a clad type rolling process, so as to finish a clad plate applied to an electromagnetic shielding field, wherein the surface of the shock-absorbing insulation layer provided with a binder faces the second electrically conductive metallic layer.
