Marking takes a variety of forms, but laser engraving is one of the most versatile and accessible. Manufacturers, hobbyists and site managers use this process in various applications. Laser-engraved awards and signs are common enough that most have seen them, but this engraving and cutting method is used in other ways. Below is some additional information on the most common uses for laser cutters and engravers.
Awards and Trophies
Laser engravers can create clean, legible carvings directly on surfaces. This factor makes the method simple to use, and it’s more durable than embossing, paint or stain. Therefore, companies that make awards and trophies use laser cutters with a co2 laser tube 100 watt on materials such as glass, metal and wood.
Creation of Barcodes
Many things have barcodes, from industrial machinery to the groceries people buy each day. While most barcodes are directly printed onto paper with an adhesive backing, this method does not work for all materials. Engravers can use a laser cutter to etch a barcode directly into an item, which can avoid problems in these situations.
When items have adhesive-proof surfaces
When items are excessively large
Where items are used so extensively that a sticker barcode would quickly wear away
Decorative and Commemorative Engraving
When buying jewelry and other gifts on special occasions, some people engrave significant phrases or dates on pieces. Sellers of these gifts sometimes offer the option to include decorative and commemorative engravings on jewelry, watches, glassware, party favors and silverware.
Medical and Electronic Devices
Certain components of medical and electronic devices need exact identification, particularly during highly stressful situations. To ensure the constant identification of important parts, certain manufacturers etch them with a laser cutter or engraver. The laser engraving process provides durability, legibility and simplicity when a high number of parts must be marked at one time.
Sign makers, gift sellers and others use laser engravers to decorate and design parts with a CNC (computer numerical control) system. A CNC system uses automated equipment to make one-off pieces as well as mass production components. Consult a metal fabrication expert or laser cutting specialist to determine whether a project’s scope warrants the usage of CNC laser cutting equipment.
