Plating Zinc Die Casting
Plating zinc die cast products is typically done for one of two reasons. First is for aesthetics, providing an attractive or decorative finish to the surface of the part. Some decorative finishes can be functional, but the main purpose of a decorative finish is to be visually appealing to customers.
The second reason is more functional where parts are going to be exposed to a harsher environment or need to be more durable. A functional finish or plating is meant to improve the component performance, which can include; hardness, tarnish, UV, surface friction & corrosion resistance; along with various other attributes.
The decision to apply a functional or decorative surface finish to a component depends upon where it will be used and its function. Products that face the consumer need to be visually appealing to customers, but they also must maintain their functional performance. A faucet must look good, but also needs to resist rust and corrosion which is a means for the decorative finish to add value.
