TTO UV Laser Marking Machine
Products Description
Most laser markers struggle when you need fine detail on heat-sensitive materials. The TTO UV laser marking machine from HGTECH solves that problem with 355nm ultraviolet cold processing - marking without burning, melting, or damaging the substrate surface. Whether you're engraving micro QR codes on medical devices or adding serial numbers to electronic components, this machine delivers consistent, readable results that hold up over time.
Built for manufacturers who need precision and reliability on the production line, the TTO series handles everything from high-volume batch marking to custom one-off engraving jobs. You get industrial-grade performance in a compact footprint that fits into existing workflows without major reconfiguration.

The system comes with an integrated galvanometer scanner that moves the beam across the marking area at speeds up to 7000 mm/s. You can mark text, logos, barcodes, QR codes, serial numbers, and complex graphics with line widths as fine as 0.01mm. The included software supports most common file formats and lets you import designs directly from CAD or vector graphics programs.

Products Application
Applications
Electronics & Semiconductor
Mark PCBs, IC chips, capacitors, and connectors with traceability codes that won't interfere with circuit function. The cold process won't damage sensitive components or cause delamination on multilayer boards.
Medical Devices
Engrave surgical instruments, implantable parts, and diagnostic equipment with UDI codes and serial numbers. UV marking produces biocompatible, corrosion-resistant marks that survive autoclave sterilization cycles.
Automotive
Mark plastic interior parts, rubber seals, sensors, and metal components with permanent identification. The system handles both black-on-white and white-on-black contrast marking on engineering plastics.
Packaging & Labels
Add date codes, lot numbers, and anti-counterfeiting marks to food and beverage packaging, cosmetic containers, and pharmaceutical blister packs - without ink, solvents, or consumables.
Glass & Ceramics
Produce fine, crack-free marks on glass bottles, ceramic substrates, and watch dials. UV processing avoids the micro-cracking common with CO2 laser marking on glass.
Promotional & Custom Goods
Engrave personalized text and graphics on pens, USB drives, phone cases, and awards. The photochemical process produces clean, sharp edges on almost any plastic or coated metal.
FAQ:
What materials can the TTO UV laser marking machine mark?
It works on a wide range of materials including most plastics (ABS, PC, PVC, PE, PP), glass, ceramics, anodized aluminum, stainless steel, copper, brass, silicon wafers, and coated metals. It's especially effective on materials that fiber lasers struggle with, such as transparent plastics and glass.
How is UV laser marking different from fiber laser marking?
Fiber lasers (1064nm) use heat to melt or discolor the material surface, which works well on metals but can damage plastics. UV lasers (355nm) use a cold photochemical process that breaks molecular bonds, producing clean marks with almost no heat effect. UV is the better choice for heat-sensitive, transparent, or high-value materials.
Can this machine mark curved or round objects?
Yes. The standard system includes a rotary attachment option for marking cylindrical objects like bottles, tubes, and shafts. For 3D curved surfaces, a 3-axis dynamic focusing system is available as an upgrade.
What's the typical marking time for a standard QR code?
A 10mm × 10mm QR code with medium contrast takes approximately 0.5 to 1.5 seconds, depending on material and required mark darkness. High-speed production settings can bring this under 0.3 seconds for simple codes.
