Most laser machines use engraving of marks into metallic or plastic components, or ablation of the surface layer to reveal the contrasting material beneath. All these processes involve laser beams at high energy.
Fiber lasers are now a common industrial tool that comes with a wide variety of capabilities that make it possible to use it on a wide range of materials. This method offers a fast ROI, low running costs, reliability and a small carbon footprint. This is the reason why it has been more accepted as a low-cost alternative to conventional lasers.
The results of laser marking are high contrast, easy to read and durable identification on a wide variety of surfaces for industrial use as well as consumer products. You can engrave a wide variety of patterns including barcodes, text, and logos.
The process is contactless and can create the marks on both metallic and non-metallic surfaces, being commonly used on glass, electronics, sporting goods, medical devices and packaging material.
The combination of a reliable industrial-grade laser, accurate and fast imaging systems and a computer control system gives the manufacturer the right mix of speed, versatility, and permanence that cannot be matched with any other marking technique.
The Laser Marking Process
Traditionally, laser marking involved making a physical mark on the surface just like the traditional methods or etching a surface of the material to reveal the underlying one. However, this has changed, and at the moment the process makes use of high-energy beams to create a change in the surface. The process is non-contact, which means that the underlying surface isn’t stressed by the process. The non-contact process also leads to low maintenance schedules, since no tool needs to be replaced. Better still, the marking is highly repeatable and machine-readable.
The Process Promotes Stringent Quality Control
The laser engraving process is usually used to mark metallic surfaces due to its reliability, speed, and durability of the results. However, it also produces fine debris that comes from the surface due to the process.
Manufacturers have to process the debris stringently. The good thing is that the process makes use of minimal engraving process that only induces a change in the color of the surface.
The use fiber laser generates the same high contrast mark on the surface, but it does so with less production of debris, which means you can easily maintain the quality you are required to stick to while enjoying reliability like no other.
Maintains a Small Spot Size
Most marking applications have come into the spotlight due to the spot size performance. However, fiber laser provides what you need in terms of spot size across all the power levels, pulse sequences and the lifetime of the laser. The spot size remains tiny, and also consistent and predictable.
The small spot size and the quality of the beam mean that the irradiance at the focus is high, meaning manufacturing tools that are equipped with the lasers produce high-quality results much faster even at low power levels. Using a focused beam means the power is localized in a very small area of the material, with the advantage that little heat is generated to the surrounding areas. This means you can perform high-quality precision marking, cutting and welding close to the most complicated or hidden areas such as joints.

Fiber laser machines make marking easy and fast. It also takes you a shorter period to handle tasks that usually took ages to complete.
