Permanent Laser Marking
& Precision Engraving

Laser marking creates permanent, high-contrast identifiers such as serial numbers, logos, barcodes, QR codes, and decorative patterns directly on the part surface without inks, labels, or mechanical contact. The result is durable, precise, and resistant to wear, heat, and chemicals.

GZTECH MOPA, UV, and green laser sources enable color marking on stainless steel, black annealing on titanium, deep engraving on tool steel, and gentle high-contrast marking on plastics, ceramics, and coated surfaces with full parameter control.

Marking Techniques
4-Step Process Overview
01
Surface Engraving

Material is ablated to form a recessed mark with excellent contrast, ideal for dies, tools, and industrial parts.

02
Annealing / Black Mark

Controlled heating creates a smooth, dark mark without material removal, preferred for medical and premium components.

03
Colour Marking

MOPA pulse control creates interference colors on stainless steel for decorative and traceability applications.

04
Foaming / Carbonising

Specific parameters produce high-contrast marks on plastics without cracking, burning, or yellowing.

Why Choose Laser Marking?


Permanent Mark

Laser marks resist abrasion, chemicals, temperature, and handling, making them ideal for lifetime identification.

Tamper Resistant
Colour on Steel

MOPA sources create vivid colors on stainless steel without inks or pigments, expanding decorative and functional marking options.

MOPA Controlled
Traceability Ready

Mark barcodes, QR codes, and Data Matrix codes with excellent scan reliability for industrial and compliance workflows.

Industrial Coding
No Consumables

Eliminate labels, ink, and printing tools. Operating cost stays low while uptime and repeatability remain high.

Low TCO
