Common printing technologies on seals

Common printing technologies on seals
There are two kinds of printing technologies on cable seals, one is by laser printing, and the other is by hot stamping. The two ways are same in meaning, just different in technologies.

Workers need to make preparation before producing ABS plastic seals for laser printing. Specialized laser powder needs to be added when injecting seals. In such way, printing is clear, just products color is not that bright. And the printing is also not that bright on aluminum seals
Comparing with laser printing, hot stamping is more convenient. There is no need of adding materials at injection. It directly hot stamps on products. The serial number and logo after hot stamping can be shown clearly, but long time later, the printing is not that clear.
