There are many ways to mark or engrave surfaces. It can be done with tools such as drills or chisels. It can be done by sandblasting or other abrasive methods, or it can be done with acids that alter a portion of an object’s surface. All of these methods are effective, but they can be expensive and they consume a certain amount of raw materials. Laser marking is a more modern way to mark or engrave surfaces. It is cost effective and requires a minimum of materials. Recent advances in the field of laser marking mean that fiber lasers are the best type of laser marking machine to use for most surfaces.
No Water Cooling
While all types of laser marking have advantages, fiber laser marking machines has the benefit of being free from the need for water cooling devices to keep them running safely and smoothly. Solid state laser machines run very hot, which requires the use of a water cooling system to prevent overheating. Water cooling systems are expensive and can be very dangerous due to their use of large volumes of liquid which can reach high temperatures. Water chillers also require constant observation and regular refilling, which can slow down the process and which can be very dangerous if someone forgets to replenish the water supply. Fiber laser marking machines use an air chiller instead, which is safer, more efficient and more environmentally friendly.
Safe and Environmentally Friendly
Due to their easy cooling method, fiber lasers are more environmentally friendly than solid state and gas lasers. They are also more “green” than most other engraving methods. Fiber laser marking machines do not introduce chemicals or particles into the atmosphere or into the groundwater. They don’t use harmful chemicals and there is no risk of spillage or leakage. These features also make laser marking machines much safer for their operators to use. As long as they take the proper safety precautions, the risk of using these machines is minimal.
One of the challenges faced by early designers of marking machines was the difficulty of marking on metal. The earliest laser markers were the most effective on wood, and other materials like plastic and glass soon followed. Fiber laser marking machines are the most ideal for marking metal, including coated metal. They were originally designed for this purpose. By applying intense heat to the surface of the metal, they melt tiny portions of it and on certain types of metal, can change the color of the surface due to a chemical reaction. The result is a permanent mark that can withstand high temperatures and frequent cleaning.
