Even if the mold has electricity, because it is CR material, it will still corrode the mold during production, so there will still be some traces on the sample surface
Even if the mold has been electrified, the CR material will still erode the mold during production, so there will still be some traces on the sample surface
Even if the die is electrified, because it is CR material, it will still erode the die during production, so there will still be some traces on the surface of the sample.
