Laser engraving of an electrode

Another laser engraving of an electrode.
In this case, laser engraving is performed on the slope at the top of the electrode.
This slope exceeds 45º.
In the two photos we can see the electrode, in the one on the left before the engraving and the one on the right after.
An interesting point in this last photo (the one on the right) is the inclination of the letters.
This inclination allows erosion in the mold by attacking it from above (i.e. from 90º).
Subsequently, this inclination will allow the demoulding of the parts to be injected, without them getting caught and broken in the extraction process.
