The 50W Fiber Laser Engraver is capable of cutting materials such as thin gold, silver, brass, stainless steel, carbon steel, and aluminum. However, the efficiency of the cutting process varies based on the metal being used. For example, the cutting thickness of gold, silver, and brass materials can range from 0.1mm to 1mm, and the time it takes to cut a 30x30mm block of 1mm brass took approximately 3 hours in a test. This versatility makes the fiber laser engraver popular among jewelers for cutting thin metals.

If you’re considering purchasing a fiber laser engraver, to help you out, I’ve gathered some helpful information below for your consideration.
Features of Fiber Laser Engravers
High ambient air temperature control options for air cooling offer a range of benefits for laser engraving. These include high efficiency with low power consumption, a low-maintenance design, and a laser source with a long lifespan of up to 100,000 hours. Additionally, they feature long pulse lengths and high peak power, enabling fast marking and deep engraving applications. Furthermore, these control options are easy to integrate into your business.
Fiber Laser Applications
Fiber laser marking, also known as laser engraving, is utilized for various applications including:
Medical Equipment – For safe and effective sterilization of medical devices, identification tags made to withstand high temperatures are engraved with fiber lasers.
Barcode and Serialization – Fiber lasers are widely used to mark barcodes, serial numbers and other codes directly onto equipment and parts, producing clear, readable marks.
Jewelry Engraving – As a means of identification and protection against theft, engraving distinct markings on jewelry has become popular.
Trademark Placement on Merchandise – For businesses that sell high-end products, laser etching their company logo can ensure brand visibility and protection against removal of labels.
Customized Products – Fiber laser engravers are also utilized for customizing products, providing businesses and startups the ability to engrave logos on industrial-level items and create personalized items such as jewelry and watches.
Automated Parts – Circuit boards are one example of the utilization of fiber laser engraving in automated parts.
Types of Fiber Laser Markers:
Fiber laser markings can have different shapes and dimensions. The capabilities of laser marking equipment determine the variety of marks that can be made. Despite these limitations, various engravings and markings can still be achieved, including:
Annealing: It involves marking metal, creating a colorful marking through a laser-generated oxidation process instead of black. The power consumption and type of metal used affect the color produced.
Color Coding: This technique operates similarly to annealing and allows for variations in color shades.
Withholding Material: In this method, only a small portion of the material is removed to create a permanent marking with the desired engraving. The top layer of the substrate is etched.
Which fiber laser for deep metal engraving?
The choice of technology and proper implementation are crucial in determining the success or failure of deep engraving text, traceability codes, and intricate artwork on metals and some polymers.
Fiber laser marking technology is a top-notch solution for high-quality engravings with depths over 0.004 inches, especially on materials like hardened or stainless steel, anodized aluminum, copper, or precious metals.
A minimum power of 50 watts is needed for most deep engraving projects. However, lower power levels can also be used for deep engraving, but it may take longer.
When comparing a 50W fiber laser engraver with a 20W fiber laser engraver, it’s clear that the former produces more detailed results.
More passes with a 20W fiber laser engraver are needed to achieve the same depth as a 50W machine, but the results will likely not be as good.
Additionally, materials that are more thermally conductive and light reflective are harder to engrave with fiber laser equipment, making a 50W fiber laser a better option.
For light marking and etching on metals, a 20W fiber laser is adequate, but for deeper engravings, a 50W fiber laser is the way to go.
Applications of deep metal engraving
The use of deep laser engraving is not limited to just one industry and is utilized by various industries such as jewelry, tool, coin, aesthetic, and shoe.
The application of deep laser engraving for both 2D and 3D designs on metal is extensive. This technique is used for creating logos, text, and artwork on gold, silver, and platinum jewelry.
FAQ’s
