After undergoing machining and non-destructive testing, components often retain residual magnetism, which can directly interfere with subsequent processing and operational performance; therefore, demagnetization is a mandatory step. The nature of the magnetic field present on a workpiece's surface is heavily dependent on the specific environment to which the workpiece has been exposed. Not all magnetic fields share identical characteristics; they can be broadly categorized into DC magnetic fields, AC magnetic fields, irregular magnetic fields, and others. Consequently, it is essential to select a demagnetization method specifically tailored to the characteristics of the magnetic field in question—typically employing dedicated DC demagnetization techniques for DC fields and AC demagnetization methods for AC fields. We offer a comprehensive range of demagnetization equipment designed to meet these diverse requirements.
