Due to the soft texture of aluminum, if a surface coating is not used, it is easily worn by the plastic, accelerating its damage and changing the gloss of the injection-molded part. The electroless nickel coating can increase the mold surface by 50RC, which is enough to protect and prolong the gloss and structure of the mold surface.
An electroless nickel coating can achieve a better surface finish quality than the aluminum itself, but it must be noted that some surface preparation is required first before the mold can be electroplated.
For example, in order to enable it to achieve a lens-grade quality level, it is recommended to first machine the surface of an aluminum mold to a SPIA-3 level finish, and then apply a 0.0003~0.0005 high-phosphorus electroless nickel coating before it is further polished , bringing it to a diamond-quality finish level.
