Laser Marking on Metal

Direct Part Laser Marking on Metal Parts

Laser marking machines are a popular choice for engraving and marking products with logos, text, and even barcodes. These machines are designed to provide precision results on various materials, including metals. Selecting a suitable laser marking machine for metals can make an impactful difference in the success of your project.

Depending on the type of material you are using, such as aluminum, stainless steel, iron, cemented carbide, copper or other metal composites, there are different processes and techniques that you need to consider to achieve the desired finish. From ceramic-filled etching to deep engravings, assessing what features your laser marking machine needs before purchasing one is critical.

As an example, laser machines with high-speed capabilities and workstation flexibility may be necessary for certain metals, given their unique properties. Additionally, your choice should reflect the purpose of the chosen laser marking machine: is it mainly for industrial production or commercial use? Once you understand these and other important factors and outline your objectives appropriately, you'll be able to find the best laser marking machine that meets all of your metal marking requirements.

Dark Metal Laser Marking

A dark metal laser marking is formed by heating the surface with a laser to form an oxidized layer. A laser marker with a fundamental wavelength, typically 1064nm or 1090nm, is recommended for either oxidation or surface annealing.

White Metal Laser Marking

White metal laser marking results from when light irradiates the target, melting the surface and creating many small and highly reflective pools. With minimal surface damage and fast marking speeds these bright pools will appear white.

Deep Laser Engraving

Deep laser engraving is the process of cutting deep marks into metal, wood, plastic, and various substances by removing material through vaporization. This process creates depth as it displaces the material being used.

Metal Laser Processing

Metal laser processing occurs through many types of production processes such as cutting, cleaning, peeling, or even welding. With KEYENCE's variety of laser wavelengths and 3-Axis technology you can find the correct laser for every job.

Metal Engraving Machines

Metal engraving machines are important and versatile tools for various industries. These machines precisely engrave or etch intricate designs into metal surfaces. However, laser engraving metal does differ a bit from laser marking. Metal engraving machines place information onto a part by penetrating the surface of the material, while laser marking marks the surface.

In either case, laser engraving metal is a common practice by many businesses across the globe. Jewelers and artists use these machines to create customized jewelry pieces and works of art. Manufacturers also use them to etch logos, serial numbers, and other imprints onto products for identification purposes. The medical industry, for example, employs this technology for engraving implants with patient information. Metal engraving machines offer quick, high-precision etching solutions with heavy-duty results.

Best Machines for Laser Marking on Metal

When deciding which laser marking machines are best suited for your needs, there are several factors to consider. First and foremost is your budget, as these machines can vary significantly in price. Additionally, you’ll want to take into account any special features you may need, such as speed control or software compatibility. Finally, you should think about how you plan on laser marking metal. Additional factors, like focal distance and the geometry of your part, will play an important role in your laser marking set up. However, the 3-Axis Hybrid Laser Marker can eliminate these types of factors as a concern.

As you see, laser marking machines are an excellent choice for businesses looking to mark metal surfaces. With their high level of precision and accuracy, these machines provide businesses with reliable results in a cost-effective manner. Choosing the right marking equipment can seem intimidating, but KEYENCE’s diverse and industry-leading collection of laser markers will help your metal marking projects go smoothly. We offer rapid support, personalized integrations, and same-day shipping to get you up and running quickly.
