Metal components require permanent markings to identify, brand, or decorate them.
Methods like dot peen stamping, chemical etching, and electrochemical marking can be used for this purpose, but laser marking stands out for stainless steel.
That is because laser markings are permanent and do not fade or blur with time. They are also faster to apply to stainless steel and highly efficient for different applications across industries.
In this guide, we explain laser marking on stainless steel and the technologies we use at Bunty LLC to achieve professional results that look flawless and are long-lasting.
Laser marking is a non-contact marking method that uses a focused beam of light to mark the surface of a material.
When a beam of light strikes the surface of stainless steel, it engraves a clean and permanent mark.
Because laser beams can be a fraction of a millimeter thin, this stainless steel marking technology is more precise and does not wear down metal components.
The results of laser marking sometimes depend on the types of lasers used. Here are four options in the market today:
| Fiber Lasers | The industry-standard marker for processing metal parts. Fiber lasers are an energy-efficient option that is very fast and precise for mass production |
| MOPA Lasers | This laser type has adjustable pulse durations that create multi-color designs or high contrast black marks on stainless steel surfaces |
| Diode Lasers | Used by hobbyists, as it is smaller and cost-effective. It’s not used for industrial applications as it lacks the power to engrave deeply into metals |
| CO2 Lasers | Not commonly used because it doesn’t directly mark bare stainless steel, and so requires extra coating of components. The metal has to be painted, coated with powder, or pre-treated with a laser bonding spray |
In the end, the characteristics of the laser marking process make it an ideal method for marking stainless steel, providing numerous advantages over alternative techniques.
Let’s discuss some of them.
Laser marking on stainless steel is far more advanced compared to traditional marking methods.
This metal marking method unlocks various benefits:
Laser markings on stainless steel are highly resistant to abrasion, chemical exposure, temperature variations, corrosion, and moisture.
After all, this method alters the chemical composition of the steel just beneath the surface, which is why markings it produces stay durable and easily legible even under adverse conditions.
This makes laser marking ideal for rugged and harsh environments.
Another reason laser marking is the go-to option for adding marks on different-sized stainless steel components is that it offers high-precision markings.
Its focused laser beams are able to create incredibly fine lines, letters, and symbols.
No other method can compare. For instance, mechanical engraving or etching often produces much coarser markings.
That’s why organizations choose laser marking for drawing micro barcodes, detailed logos, and other custom patterns, every single time.
Laser marking is not a manual process. It is computerized and automated to mark components fast and without errors.
On top of that, laser marking technology does not require drying time or tool changes during operation, which speeds up metal component manufacturing.
In industries where time is money, that is incredibly valuable.
The sheer quality of laser marking of stainless steel makes it suitable for commercial, decorative, and industrial applications.
Here are some examples.
Laser marking is highly favored in the manufacturing of medical equipment.
That is because they create permanent marks that are highly readable, without cutting into or deforming the shape of the metal parts.
By avoiding deep engraving into stainless steel, the medical components and equipment are easier to sterilize and clean, making them safe to handle people and animal health.
In other words, laser-marked medical equipment is commonly used as surgical instruments, medical implants, lab tools, diagnostic equipment, and hospital devices.
Laser marking is used to make permanent tracking information on industrial-grade stainless steel components.
This option is the top pick for business owners because it’s able to clearly capture detailed QR codes, 2D data matrix codes, serial numbers, barcodes, plus any industry specifications and safety warnings.
Unlike other markers that fade over time and may not hold up under intense activity, laser marking can withstand many years of intense vibration, heat exposure, chemical oils, and rough handling.
Laser marking is also an effective way to brand components by placing brand information directly on the surface of the metal.
Things like company logos, brand symbols, taglines, and slogans can be added to stainless steel equipment and machinery.
It is frequently used in appliances, industrial products, consumer goods, premium equipment, and more.
Besides identification, laser marking is a great way to add decorative details to stainless steel, as it allows users to create intricate designs, artwork, patterns, and textures.
Decorative laser marking is particularly important for jewelry, watches, architectural panels, interior design, luxury consumer products, custom gifts, and awards.
Achieving high-quality laser markings on stainless steel is necessary to identify, brand, and decorate the parts.
