Plating Metals

Plating is a critical step in manufacturing where a metal is applied to the surface of your work piece. Plating has been used for hundreds of years for decoration, but in modern technology its purpose is far more than just decoration. Various materials are plated to help slow corrosion, to reduce friction, to harden the surface of your work piece, for radiation shielding, to help paint adhere, and many more reasons.

Often used in electronics, gold and silver plating is the process of depositing a thin layer of either gold or silver on another metal. Typically used in electronic connectors and printed circuit boards, this type of plating adds an electronically conductive layer that is resistant to corrosion. Chrome plating is a finishing treatment that is used to leave a bright shiny mirror-like quality to things like furniture frames and car trim. Plating with zinc oxide provides a barrier between the coated metal and helps to prevent oxidation and rust. Tin plating is widely used in the food industry because it is non-toxic, resistant to corrosion, and easy to shape without damaging the tin layer.

Gold plating is also called gilding. This type of plating dates as far back at the Old Testament. Modern gilding can be applied through many different processes onto many different surfaces. Plastics, wood, leather, etc can not be gold plated. However, previously chromed metals and previously gold plated items can be replated and look new again.
