How Metal Coating is used in Electronic Devices

Technologically advanced electronic devices require internal protection of many parts for durability and functionality. Metallizing some of the internal parts, such as desktop computer cases and internal computer fan components, helps keep them working longer. This extra step in production also adds longevity to the life of the device.

Heat Protection
Inside a computer or electronic device, heat is created as the device is used. This also happens when portable devices are charged. Heat can cause wiring and thinner metal pieces to warp or melt inside the device. With a metal coating on vital parts, protection against heat damage is in place.

Moving Parts Protection
In electronics devices with moving parts, keeping the friction to a minimum is ideal. This prevents the parts from wearing down and becoming vulnerable. As gears intertwine with each other, there is a minor amount of rubbing that occurs. It can lead to the chipping off of gear tips, which leads to gear malfunction. One single gear, working improperly can completely shut the device down.

Corrosion Protection
Items with internal batteries are subject to corrosion. Corrosion can lead to a device catching fire or becoming unusable. Corrosion spreads quickly in an enclosed space. Metal coating can help protect vital internal parts from corrosion damage.
The type of coating used for corrosion protection should also be solvent resistant. If the parts are cleaned or exposed to chemicals, the coating could be eaten away, leaving the device vulnerable.

Color Coding Finishes
When multiple pieces that look similar in a device are used, consider color coding them. Metal coatings are available in multiple colors. This also helps match the interior of a device with the exterior for design purposes. In instances where similar parts are used for alternating manufacturers, this helps decipher the proper parts for the specific piece being made.

Metal coating is used in multiple industries. Auto manufacturers and aerospace industries use the process for both protection and visual appeal. With this process, electronic devices can endure more use with less malfunction. The coating is quite thin, however, it is durable to withstand years of wear and tear. Ensure that the type of coating used is the right option for the application the piece will be used in to optimize efficiency.
