In one embodiment, the electronic product housing is forged by the die in any one of the above embodiments, and the forged electronic product housing is anodized to find that the surface of the electronic product housing has a different color. This is due to the inconsistent density of the electronic enclosure. In order to prevent the electronic product shell from generating different colors after being anodized, the compression amount of the electronic product shell is independently scaled, namely the compression amount of the electronic product shell by the mold is changed.
The compression amount is independently scaled, that is, the compression amount of the electronic product housing by the mold is changed by repairing the mold and reworking the mold, for example, repairing a position corresponding to the cavity of the mold.
As shown in fig. 6, fig. 6 is a schematic structural view of a mold in one embodiment. The
