Laser engraving and laser etching are similar processes with some differences.
- Laser engraving creates much deeper markings than laser etching. This is ideal for high wear parts requiring durability.
- Laser engraving also generates more heat than etching, making it less compatible with thinner or more sensitive materials.
Some of the benefits for laser engraving and etching include:
- Better legibility
- No drying
- Long term durability
- Resistance to high temperature sterilization
Laser engraving locally vaporizes surfaces creating a visual and tactile code. Since laser engraving and etching do not involve particle blasting, there is a significantly reduced chance of surface damage or deformation. The markings produced are also more legible than other engraving methods.
Some of the more common laser engraving uses include:
- Barcodes and QR codes
- Logos and other branding
- Contact information
- Serial numbers
- Part numbers
- And other identifying marks
Our laser engraving processes utilize three different marking systems to meet the needs of your specific project.
- UV, or ultraviolet lasers produce shorter 355nm wavelengths and can be used for non-thermal processes including color changes.
- Green lasers produce a 532nm wavelength that allows for extremely precise, high speed engraving of plastics and metals.
- YAG lasers produce a 1064nm wavelength for engraving metal and harder plastics.
