Engraving and laser marking are both methods of creating permanent markings on materials but differ in technique and application:

• Engraving: This process involves physically cutting or etching a design into a material’s surface using a mechanical tool or laser. It removes material to create deep, permanent markings, making it ideal for serial numbers, logos, and decorative designs.

• Laser Marking: This method uses a low-powered laser to discolor the material’s surface without removing it. It creates high-contrast marks by altering the material’s properties through heat, oxidation, or chemical reactions. Common in medical, automotive, and electronics industries, it’s used for barcodes, QR codes, and branding.

Both methods provide durable, precise, and high-quality markings, but laser marking is generally faster and non-contact, while engraving offers deeper and more tactile results.
