What are the reasons for the failure of soft label demagnetization?

There are several possible reasons for soft label demagnetization failure, including the following common causes:

Demagnetization device malfunction: Insufficient power or aging of the demagnetizer prevents it from effectively demagnetizing the magnetic field in the soft label.

Incorrect demagnetization device settings, such as mismatched demagnetization frequency and intensity, may prevent the demagnetization process from being completely removed.

Damaged soft tags: The tags themselves may be damaged or have quality issues, such as a broken chip or magnetic material, which can cause the demagnetization process to fail.

Excessive aging or uneven magnetic material on the tags can also affect demagnetization effectiveness.

Incompatibility between label type and demagnetization device: Different soft labels require different types of demagnetizers. If the demagnetization device used is not compatible with the label type, demagnetization may not be possible.

Incompatibility between the label frequency and the demagnetization device frequency can also lead to demagnetization failure.

Improper operation: Failure to operate the demagnetization device correctly can lead to demagnetization failure. For example, improper label placement or angle during demagnetization may result in incomplete magnetic field removal.

Excessive distance or insufficient contact between the tag and the demagnetizer can result in poor demagnetization.

Metal objects or other interference sources near the tag: Metal objects near the tag can interfere with the demagnetization process, preventing effective magnetic field removal.

Electromagnetic interference or other electronic devices can affect the demagnetizer's operation.

Insufficient demagnetization time: If the demagnetization time is too short, the magnetic field on the tag may not be completely removed, potentially causing the soft label to remain detectable.

By examining the above causes and making appropriate adjustments, you can effectively resolve the issue of soft label demagnetization failure.
