FIBER LASER ENGRAVING
Fiber lasers are a relatively new technology that have shown very promising results: they can offer better quality in marking and deep-engraving thanks to short pulse duration minimizing thermal effects and faster speed processing with high peak power pulses.
What is Fiber Laser Engraving?
Laser engraving is the process of removing a portion of material to leave an engraved mark which is visible beneath. The engraving process is produced by the Laser beam removing material to create a mark, where the Laser acts like a chisel and blows away selected areas of the subject material. It is a subset process of laser marking where the object is actually marked beneath the surface and is the most common of all the laser marking methods. The depth of the engraving made will depend on the dwell time as well as the type of material being used.
There are two types of Laser engraving. Light engraving is where a relatively shallow trench is created, between 5µm and 25µm. The depth achievable depends on the material, and also the power and the dwell time of the Laser. Deep engraving is used for making moulds and dies, stamps, etc. The depth that can be achieved is entirely dependent on how the material absorbs the Laser, how much energy the Laser has, and how long the Laser can dwell on the target. Deep engraving is usually a fairly slow process. Both types of engraving can be carried out on surfaces such as different metals and some plastics.
Popular uses & applications:
Laser engraving has many industrial uses. Laser engraving can be used for traditional marking purposes such as identification or serial numbers and logos but has the advantage of depth which makes it popular for making stamps, dies and moulds.
The laser is one of the most versatile modern inventions. Lasers are used in almost every industry, including: Automotive, Industrial & Tooling, Electronics, Medical, Military & Defense, Aerospace, Oil & Gas and much more.
Benefits of Fiber Laser Engraving:
- This is the fastest way to mark with a laser.
- You can engrave on almost any kind of materials: metal, plastic, wood, leather and glass surface.
- Produces a high-contrast, permanent mark
- Does not affect the integrity of the part
- Engraving using Fiber Lasers is a more environmentally friendly approach as inks and bit heads which are used with traditional techniques are no longer required. The fact that the process is contactless also has direct benefits of reduced “wear and tear” compared to the use of tools.
