Application – Laser Marking
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).
Popular laser marking applications and industries
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.
And it 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 very popular:
First of all, cars (such as component markings – such as spark plugs),
Second, electronics (such as printed circuit boards), medical (such as marking medical implants),
Third, aerospace (such as point shot peening and cockpit marking), semiconductor manufacturing.
Finally, jewelry and other industries.
