Powder Coating Powder coating is another common decorative finish you can use for your die casting part. It involves applying charged particles on the surface of the die casting part. This process is ideal as it hides minor flaws on the die cast surface, has better thickness control and is uniform. Consequently, the product becomes durable, hard, high anti-corrosion and anti-scratch on completing the process. Powder coating is environmentally friendly as it produces no hazardous toxic material Antiquing This surface finish technique gives the cast an antique look, and it is mostly applicable to zinc casting. The casting is electroplated with copper or other alloys and then covered with a colored component such as copper sulfide. The casting is relieved (i.e., removing some colored layers to give the underlying later of copper) and then treated to prevent tarnishing. Ceramic Coating Ceramic coating is a decorative process and involves adding ceramic in its solution form to the exterior of a part. The process produces a thin layer that is similar to anodizing. Consequently, surface preparation procedures are important before their applications. Plating Plating can be electroless or electroplating processes and is a suitable and cheap method for die cast finishing. As the ceramic coating option, the layer of finish is thin. Therefore, you need a surface preparation procedure before using it. Electroless plating uses chemicals instead of electricity to plate a diecast part. The die casted part is placed in a chemical with reducing properties. When catalyzed by other minerals, the chemical becomes deposited on the die cast. Electroplating is similar. However, instead of being catalyzed by minerals, the catalysis occurs by passing a current through the electrolyte. Both methods are ideal for aesthetic purposes. Although some sheet metal enthusiasts use it to improve some parts’ conductivity.
