Metal Engraving: Techniques and Applications for Durable Markings

Metal Engraving: Techniques and Applications for Durable Markings

February 7, 2024

The process of carving designs, text, or examples into various metal surfaces is known as metal engraving and is a renowned kind of art. Metal engraving delivers unmatched durability and long-lastingness, and as a result, it is a tactic that has withstood the test of time. Engraving is an accurate and efficient solution whether you’re looking to modify diamonds, create Custom Name Plates, or add enduring figures to industrial parts. In this article, we’ll examine metal engraving methods and applications revealing the adaptability of this reliable specialty.

 Metal Engraving?

The technique of engraving metals allows for the marking of text, logos, numbers, images, 2D codes, and other items. This method of processing a logo or character includes making cuts on metal surfaces to draw lines, letters, or other patterns. Metal pieces that have been laser etched are used in the operations of several sectors, including automotive, medical, jewelry, energy, and aeronautics. This strategy may be used by project managers and business owners to brand their products. Using various engraving techniques, text, serial numbers, logos, codes, and other items may be etched into various metal materials.

Laser Engraving

One of the quickest and most dependable methods for adding marks to objects is laser engraving. The method depends on laser beams’ capacity to melt predetermined regions of the component in predetermined patterns. Sublimation is a process that turns metals into gasses without turning them into liquids. The part’s surface sublimes as a result of the laser beam’s intense energy input. The material’s surface will change to have a strong contrast as a result. Barcodes, logos, serial numbers, component numbers, and QR codes may all be engraved with the aid of this method. This technique is well-liked for metal engraving because of its excellent dependability. Compared to laser etching and marking, laser engraving on metal produces deeper dents and is quick.

Materials For Laser Engraving

  1. Metals:  In many industries, metal serves as the main component. Aluminum is the best metal for laser engraving out of the several that are appropriate. However, stainless steel, which is made up of several alloys, also functions superbly with this method. In reality, engraving on stainless steel is a common engraving service for many sectors.
  2. Coated Metals: Metals that have coatings can also benefit from laser engraving. Because it may remove the coating or polished surface, it is a special technique that facilitates the marking of coated metals. On mild steel, powder-coated stainless steel, coated aluminum, and other types of coated metal, laser engraving works well.
  3. Plastic: The temperature required for laser engraving on plastic often fluctuates. The spectrum of absorption of the plastic used and the additives added during the production process cause variations. The following plastics can be laser engraved: ABS, acrylic, polycarbonate (PC), PET, and polypropylene (PP).

Advantages OF Laser Engraving

  • Speedy Production Cycle

The process is swift and may be finished in 3 to 5 minutes, depending on the material, design, and laser power. The procedure is crucial in quick production because of its speed.    

  • Variety Of Materials

Unlike marking technologies like dot peening and chemical etching, it is suitable for a variety of materials like metals, wood, and plastics. 

  • Accuracy

Although the precision varies depending on the type of equipment and its parts. Laser markers offer excellent precision and accuracy and can be engraved at +/-.01″. It may be used in the jewelry, medicinal, and electrical industries because of its accuracy.

  • Repeatability

Laser markers are suitable for the batch marking process due to their reproducibility. The design is stored in the machine’s software, which may mark and collect the same marks on other or related pieces. Repeatability ensures quicker response times and aesthetically pleasing items.

  • Longevity 

Laser-etched marks are more noticeable due to their high contrast and longevity. As a result, they can withstand various environmental factors including abrasion, heat, and chemicals. As opposed to marking methods like inkjet marking, where the marking substance may wash off under poor conditions.  Laser-engraved marks are useful for product identification and traceability due to their longevity.

  • Sustainable Production Methods

It doesn’t need consumables like chemicals that might harm the environment, unlike inkjet marking. Additionally, they don’t make any noise, in contrast to dot-peening machines. As a result, the process is energy- and environmentally-friendly and clean.  

  • Marking Without Contact

The non-contact marking process prevents material contamination and the component’s mechanical or physical properties from being altered. Contrary to dot peening, where the stylus strikes the materials, and inkjet marking, where chemicals may not be compatible with the materials, this does not include doing so.
