The use of zinc in a coating or plating process is not new, but there have been significant advances in technology and process control that make this a very precise metal finishing option for parts and components across a wide range of industries.
The ability to use zinc electroplating on small and large parts with simple to complex shapes and design features makes it a natural choice for parts in the automotive industry. Pairing this practical aspect of using zinc plating with the exceptional resistance to corrosion and long life cycle, even in high-temperature types of applications is a clear indicator that this is often the right match for your needs.
Additionally, the cost of zinc electroplating is very reasonable, and it is a fast process that can be completed for large volume orders with the same precision as with smaller orders. New technology allows for a superior thickness distribution of better than 2:1 between high and low current density area.
Experience and Final Finish
As with any type of outsourced service, it is critical for an OEM to take the time to find a company with a specialized focus on zinc electroplating. While any metal finishing company can do basic work when it comes to precision plating, the details make the difference.
Correct Preparation
An experienced company does more than just understand the principles behind the process; they have the process managed from prepping the metal through to final finishing. They also take the time to ensure the parts are correctly cleaned and prepared for the zinc plating process.
This step is often overlooked or incomplete with inexperienced companies or those services trying to focus on the volume of metal finishing rather than exceptional quality. This can lead to failure of the zinc plating over time, resulting in faster corrosion and a less durable part.
