When it comes to custom-engraving metal, few processes provide speedy and precise results, like metal laser engraving. Using the power of a laser to vaporize the material into a detailed design, a top-notch metal laser engraver (like a CO2 laser engraving cutting machine) can provide exceptional results for virtually any metal product or part. From stainless steel to aluminum, metals of all thickness can be efficiently engraved with a laser engraving metal machine or, more productively, a laser engraving services provider.
However, manufacturers, artists, and businesses of all sizes that require engraving for their products may not inherently know how to laser engrave stainless steel or how to engrave metal in general.
So, let’s take a closer look at the process, and when you’re ready to learn more, reach out to the experts at Steelway Laser Cutting. For decades, we’ve been the trusted resource for laser engraving and laser cutting services across all sectors. Our engineers are glad to be your partner for any laser engraving project on the horizon.
How Does a Laser Engraver for Metal Work?
When it comes to how to laser engrave metal, the process is somewhat like laser cutting, depending on the advancement of the machine. The best laser engraving machines operate with minimal manual intervention. Detailed designs and instructions via computer aided design (CAD) software are fed to the computer numerical control (CNC) machine, which then dictates the specifications for each workpiece.
Once the instructions are in hand and the process is ready, the laser engraving machine creates deep or minor crevices (depending on the specs) through the sublimation process. Then, it instantly turns solids into gas while bypassing the liquid phase. In order for the process to work, the laser engraving machine must generate enough energy to allow the workpiece’s surface to reach the peak vaporization temperature within milliseconds. Additionally, that means that laser engraving steel, aluminum, or even copper or brass requires a powerful laser engraving machine to be effective.
Preparing the Metal Surface
For laser engraving to be most efficient and productive, there are a few steps that manufacturers should take before the engraving process begins. Especially when it comes to laser engraving metal and other more challenging materials.
- Review your design thoroughly – Once the CAD-created instructions are fed to the laser engraving machine, the process will run uninterrupted until the full project is complete. So, ensure that your design is perfect. This is especially important when it comes to letters, numbers, verbiage, and other essential information, like barcodes, logos, or instructions.
- Prepare the surface – Laser engraving works best with a clean and debris-free surface. Therefore, take any steps required (cleaning, polishing, coating, etc.) to ensure your surface is as smooth as possible before the engraving begins.
- Have a clean work environment – Laser engraving service providers like Steelway use a state-of-the-art facility to perform the laser engraving process. Our team ensures that the environment is clean because it is essential when it comes to preventing errors or alterations to the finished laser-engraved products.
- Set up your proper parameters – The end result of the laser engraving process will also depend on the settings on your laser engraving machine. So, double check the speed, power, resolution, and other factors that will determine the depth, width, and design of the engraving.
Different Types of Materials that Can be Handled with Laser Engraving Services
When it comes to the types of materials that can be laser engraved, the sky is the limit! A sample of the different raw materials that can be processed with a laser engraving machine includes the following:
- Stainless steel
- Aluminum
- Titanium
- Brass
- Copper
- Plastic
- Wood
- Glass
Remember that the effectiveness of laser engraving depends on the type of laser engraving machine utilized in the process. Therefore, be sure that your laser engraving machine can handle the tougher and/or more delicate materials required for your project.
Laser Engraving Tips
There are a few steps that you can add to the process to ensure the laser engraving process runs smoothly from start to finish without any errors. Before you start to use a laser engraving machine, be sure to consider the following tips:
- Use masking, especially when using a less effective laser engraving machine – Not all laser engraving machines are created equal. So, if you are using an older or less powerful machine, then the smoke from the engraving process may stain the edges of the engraved surface. Masking tape is a simple and inexpensive solution that may minimize any damage.
- Perform a test cut – Performing an initial test cut is imperative, especially if you intend to engrave multiple products or parts simultaneously. Be sure to review the results carefully and adjust the laser engraving machine settings as needed based on the test results.
- Add a finishing, like powder coating – Again, depending on the laser engraving machine, you may need to add a post-process coating, like paint or powder coating, in order to eliminate any minor blemishes or rough edges from the engraving process. Adding a finishing coating can also extend the life of your product or part, depending on the material.
Unlock the Potential of Laser Engraving with Steelway Laser Cutting
Laser engraving can make any manufacturing process more efficient in virtually any industry. Laser engraving excels in various applications, from inscribing essential details such as instructions or barcodes on mass-produced products like automobile parts or appliances. It is also perfect for creating logos and decorative designs that distinguish a product. This method is the most streamlined and technologically advanced process, especially when employing the right tools and skilled technicians.
This is why if you’re new to easing engraving metal or any type of material, you need an exceptional resource.
