UV laser marking machine: ideal for precision marking and heat-sensitive materials

Some materials, due to their unique physical and chemical properties, are not suitable for fiber laser marking machines. Plastics, glass, acrylic, ceramics, and some coated or soft metals can suffer from excessive heat damage, rough edges, or poor contrast when marked with fiber lasers. In these cases, a UV laser marking machine becomes a far better choice. Operating with a shorter wavelength and lower thermal impact, it delivers clean, high-contrast marks without damaging the surface—making it ideal for industries where precision and appearance are critical.

What is a UV Laser Marking Machine?

A UV laser marking machine uses a 355 nm wavelength laser, generated by third-harmonic generation (THG) technology. Compared to fiber or CO₂ lasers, UV lasers produce a much smaller spot size and have higher photon energy, allowing for micro-fine marking with exceptional clarity.

Key characteristics:

Ultra-fine beam for precision marking

Minimal thermal impact (“cold marking”)

High absorption rate for plastics and other sensitive materials

Capable of micro-text engraving, QR codes, and intricate designs

Why Choose UV Laser Marking?

Compared to traditional marking methods, UV laser marking offers significant advantages:

No consumables – No need for inks or labels, reducing operating costs.

Non-contact process – No mechanical wear or pressure on the material.

High contrast, permanent results – Resistant to fading, abrasion, and chemicals.

Eco-friendly – No hazardous waste, complies with environmental standards.
