Benefits of using laser marking machines for gold applications
Gold engraving using lasers is a particularly apt technology because it results in less wastage of material. Since the material could literally be worth their weight in gold, even a small amount of this precious metal etched away could be an expensive loss.
The quality and reliability of this metal is unparalleled. It can produce high-quality engravings that are permanent, accurate, and legibly display even the smallest details. The software allows jewelry makers to very easily load image and design files, and to produce models before marking on the actual jewelry. The accuracy and reliability of laser marking are highly prized when working with precious metals – after all, a mistake in this field could prove to be very costly.
With this in mind, the annealing process has become the standard process for etching, engraving, marking or cutting this material. In annealing, a colour change is achieved on the surface by oxidation of the material without any material loss. Since gold is an incredibly soft metal, marking it successfully requires high-speed and very little power – with just a 20W laser, a simple design is completed in a fraction of a second.
