Yes, laser marking is considered permanent. This featured performance is one of the key advantages of laser markings. Unlike other types of marking, such as inkjet printing or labels, which might fade, wear off, or be readily erased, laser markings are deeply etched or engraved into the surface of the material. They are consequently very resistant to:
● Abrasion: Even in high-friction conditions, laser marks are resistant to being scratched or worn away.
● Chemicals: Laser marks are often resistant to contact with a variety of chemicals, such as acids and solvents.
● Environmental Considerations: They are resilient to UV light, moisture, and temperature changes.
● Modification: Without causing harm to the underlying material, it can be hard to change or delete laser markings.
Due to its durability and resistance to external influences, laser marking is widely utilized in fields where long-lasting, legible marks are required, including aerospace, automotive, electronics, and medical. It is a reliable process for branding, personalization, and traceability of products that guarantees the marks are identifiable and permanent for the duration of the product’s lifecycle.
