Aperture Type Demagnetizers
Aperture Type Demagnetizers are widely used to demagnetize tools, cutters, small parts, bearing components, and assemblies. The item is simply passed through the aperture and then removed from the demagnetizing field. Care should be taken to make sure that the workpiece is well away from the demagnetizing field before the demagnetizer is switched off.
For production lines, a non-metallic chute may be used to slide the parts through the aperture.
Walker Aperture Type Demagnetizers are designed to operate on alternating current at 100% duty cycle and are also available as the only compensated units on the market, providing field strength which increases with workpiece volume. These units idle at their lowest current level, and increase the current flow and demagnetizing field when presented with a work piece. They are available in table top and floor stand models in a variety of aperture sizes.
Aperture D.C. Demagnetizers also are available for demagnetizing large volume parts such as engine blocks, and machine casting and die blocks. The D.C. Demagnetizer uses a series of pulses of alternating polarity and decreasing amplitude to accomplish demagnetizing.
