Ultra-precise 355 nm cold marking on glass, PCB, plastic, ceramics & heat-sensitive materials
UV Laser Marking Machines are advanced precision laser systems designed for ultra-fine and high-accuracy marking applications. These machines use ultraviolet laser technology with a shorter wavelength, allowing highly detailed marking with minimal heat effect and exceptional surface protection. UV laser marking is especially suitable for delicate, heat-sensitive, and high-precision materials where traditional laser systems may cause damage or burning. The machine delivers clean, sharp, and permanent markings on plastics, glass, ceramics, silicon, electronic components, medical devices, and coated materials. These systems are ideal for micro marking, QR codes, serial numbers, logos, barcodes, date coding, and precision engraving applications requiring superior clarity and accuracy. Due to the cold marking process, UV lasers minimize thermal stress and maintain the original quality of the material surface. UV Laser Marking Machines are widely used in industries such as electronics, semiconductor manufacturing, medical equipment, cosmetics packaging, mobile components, precision instruments, and high-end industrial applications where fine marking quality and reliability are essential.
We offer a wide range of imported UV laser machines sourced from globally recognized manufacturers. These products meet international quality standards and are ideal for high-resolution marking and micro-engraving on delicate materials. Our imported UV machines feature premium DPSS laser modules, advanced galvo scanning systems, and industry-leading beam quality — delivering consistent, repeatable results across demanding production environments throughout India.
A UV laser marking machine uses a solid-state diode-pumped (DPSS) laser to generate a 355 nm ultraviolet beam through a process of frequency tripling from the fundamental 1064 nm infrared wavelength. Unlike thermal laser processes, UV light interacts with material at a photochemical level — breaking molecular bonds directly rather than melting or vaporizing through heat. The focused beam is steered by a high-speed galvo scanning head and positioned with sub-micron accuracy, producing extremely fine, clean marks on even the most delicate surfaces without any surrounding thermal damage.

Common questions about UV laser marking machines, pricing, and operation in India.
It is used for ultra-precise cold marking and engraving on heat-sensitive materials like glass, plastics, PCBs, and ceramics. Its short 355 nm wavelength prevents thermal damage, making it perfect for delicate substrates.
It marks a wide range of materials, including glass, silicon wafers, PCBs, ceramics, white plastics (PVC, PP, PE), packaging, and most transparent surfaces that fiber or CO2 lasers fail to mark.
Cold marking is a photochemical process where the UV laser breaks molecular bonds directly instead of using heat. This leaves a near-zero heat-affected zone, eliminating micro-cracking, charring, or warping.
Prices typically range from ₹2.5 Lakhs to ₹10 Lakhs depending on the wattage (3W–15W) and system setup. They cost more than fiber or CO2 systems due to high-end optical components. Contact us for a quote.
Yes. It is the electronics industry standard for marking micro-text, barcodes, and serial codes on PCBs. The cold marking method protects circuit layers, ensuring electronic integrity is never compromised.
