Pulsed Fiber Lasers are renowned for their versatility with laser marking being one of the most popular applications. Although similar to laser engraving, the appliance of a mark is at a surface level, whereas engraving is a mark with depth. Laser marking is the process where a material, which can be anything from ceramics, plastics, metals, LEDs, rubber, graphic composites, etc. is marked or labelled with a simple black mark, or in colour (depending upon the material).
Laser marking is typically used for processes such as applying labels with bar codes, date codes, QR codes, serial numbers, part numbers or adding copyright/trademarks and logos to a number of different surfaces being commonplace across many industries.
Another popular use is the addition of a date value being added to materials such as metals and plastics; this could be used as a best before date or maintenance due date, etc. Additionally, marking is very useful in security applications such as the creation of ID and smartcards offering high degrees of fraud prevention.
Night and day marking is another very popular application. This is the marking of components with marks which can be seen both at night (via backlighting) and day, this is popular for signage and on car dashboards as examples.
Marking with a laser is extremely popular in manufacturing industries and is widely integrated into sub-processes across the production line. Laser marking is also popular in automotive (e.g. component marking – such as spark plugs), electronics (e.g. printed circuit boards), medical (e.g. marking medical implants), aerospace (e.g. dot peen and cockpit marking), semiconductor manufacturing as well as other industries too.
There are many advantages of using a laser over other marking methods. Marks using this technique tend to be much more durable than through other methods. The process is non-contact and uses a much lower number of consumables. Marks can be 100% accurately added in large batches, through a process which is highly repeatable. When you think of these benefits and the fact that process times are much lower it’s no surprise the process is becoming increasingly popular. Buy the perfect SPI Laser for you, we manufacture a range of Pulsed and CW Fiber Lasers which will exactly match the beam quality and power level required for the marking task needed.

SPI Laser’s reliable and robust Pulsed Fiber Lasers combine a wide range frequency pulsing output with high peak power to deliver highly precise, efficient, and durable marks that will last.
Also, remember that SPI Lasers can be used for a wide-variety of other purposes, as well as being a useful laser marker, they can also be used for welding, drilling, engraving, cutting, etc. These can all be programmed into one seamless process for ultimate efficiency.
For a basic black mark or any combination of coloured marks, an SPI Laser is an excellent purchase which is used globally by industrial manufacturers. Our Lasers combine a wide range frequency pulsing output with high peak power to produce long-lasting very fine, extremely precise, controlled marks and ablation. Using a galvo mirror delivery these units can mark almost any material at very high speed. We produce many different models to match the power level and beam quality required for the task at hand.
Laser markers are easily integrated with material handlers, X-Y tables, galvos, rotary axis drives, bowl feeders, conveyors, dial tables and other industrial manufacturing equipment.
