Zinc alloy die-casting the whole process of the greater depletion of the stage must be attributed to the metal surface treatment, in which and electroplating process processing method is greater, then how to deal with this poor plating process goods?
Zinc-aluminum alloy die-casting is──a kind of aluminum die-casting parts with zinc as the main component. These parts have a high-density surface, and the inside is a firefighting sparse porous material, but also a cheerful amphoteric metal. Therefore, only the choice of moderate former solution and plating can ensure that the plating process layer on the zinc alloy material has excellent adhesion and achieve the provisions of qualified products.
The common raw material of zinc alloy material for electroplating process is ZA4-1, whose main components are: aluminum 3.5% to 4.5%, copper 0.75% to 1.25%, magnesium 0.03% to 0.08%, capacity of zinc, total residue ≤ 0.2%. And 925 models of zinc alloy materials with high copper content, but also to facilitate the plating process. In general, the relative density of zinc alloy material is 6.4 ~ 6.3g/cm, if the relative density is <6.4g/cm, the electroplating process is easy to produce bubbles and black spots. In a word, try to strictly supervise when selecting materials. In addition, aluminum die-casting when the abrasive tool must be designed program effective, to prevent the plating process to produce insurmountable shortcomings (such as black spots).
Zinc alloy die-casting process in the current market listing most of the mold manufacturers use a mold production technology, the use of this constraint produced by the product either in terms of quality or in terms of price is far better than the other products are much better. It is also the product that users prefer now.
