UV laser marking machines (typically 355 nm “cold” lasers) are preferred when you need ultra-fine, high-contrast marks with minimal heat-affected zones on plastics, glass, silicon, and delicate metals. Buyers in India often compare price against output quality, line speed, uptime, and after-sales support. As a ballpark, UV laser markers span from compact 3 W entry systems to high-throughput 10–15 W lines with automation. Price varies by wattage, brand of laser source and scanners, marking area, vision systems, fume extraction, and integration needs. This page explains how pricing is formed, what features matter, and where to buy from a reliable manufacturer—so you can budget wisely for your production, compliance, or branding requirements without compromising lifetime value.
Working Principle & Process Flow
UV laser marking uses a short-wavelength beam (around 355 nm) generated by frequency-tripled solid-state lasers. The beam passes through galvanometric scanners and an F-Theta lens to rapidly position and focus on the target surface. Instead of melting the surface, UV photons typically cause photochemical reactions (ablation or color change) at low thermal load—ideal for polymers, glass, medical devices, and electronics. The operator prepares art or codes (text, QR, UID, batch) in the marking software, sets parameters (power, frequency, speed, hatch), and starts the job. With inline encoders/sensors, the system can mark on moving conveyors. Vision checks confirm readability and placement, while fume extraction keeps optics clean. This “cold marking” flow delivers crisp edges, low burr, and superior legibility for tiny fonts and micro-codes.

“Cold” marking → minimal heat-affected zone, no substrate warping
Ultra-fine spot size for tiny fonts and dense 2D codes
Excellent contrast on clear/colored plastics and coated surfaces
Low consumables, clean process, and minimal maintenance
Key Features That Influence Price
Laser Power & Brand: 3–5 W for light coding; 10–15 W for higher speed/contrast. Reputed sources cost more but offer stability.
Marking Field & Optics: Multiple F-Theta lenses (e.g., 70×70, 110×110, 150×150 mm) affect cost and flexibility.
Motion & Automation: XY tables, rotary axes, conveyors, and enclosure interlocks add budget but boost throughput and safety.
Vision & Traceability: Camera alignment, code grading (ISO/IEC), and MES connectivity are premium add-ons.
Cooling & Dust Control: Efficient thermal design and fume extraction preserve optic life and reduce downtime.

Maintenance & Safety Tips
ChecklistTechnolaser
Monthly / Quarterly
Inspect optics (protective window, F-Theta lens) and clean with approved wipes to avoid energy loss and hot spots.
Verify galvo scanner health, run test patterns, and recalibrate field if marks drift.
Service cooling and fume extraction; keep airflow paths clean to protect the laser source.
Operating Best Practices
Use validated parameter sets for each polymer or glass; avoid over-powering to prevent charring or micro-cracks.
Grade codes (DMC/QR) routinely and log OEE; tune hatch and frequency for consistent contrast.
Follow Class-UV safety: proper enclosure, interlocks, eyewear rated for 355 nm, and restricted access.
FAQs — UV Laser Marking Machine Price
Q1
How much does a UV laser marking machine cost in India?
Pricing typically starts from compact 3–5 W systems for small batches and scales up for 10–15 W, larger fields, vision grading, and automation. Request a line-item quote to compare base machine vs. add-ons.
Q2
Which factors impact the final price the most?
Laser wattage/brand, optics set, enclosure and safety, motion/automation (rotary, conveyors), camera alignment and code grading, and integration to MES/PLC are the biggest drivers.
Q3
Can UV lasers mark metals as well as plastics?
Yes—especially on coated or anodized metals and finely finished parts. For deep engraving on bare metals, fiber lasers are usually preferred, while UV shines on delicate, heat-sensitive substrates.
Q4
What throughput can I expect?
Throughput depends on code size, fill density, and substrate. With 10–15 W UV and tuned parameters, inline marking of small parts and fast code cycles is achievable with high read rates.
Q5
How do I budget for ownership beyond purchase price?
Include preventive maintenance, optics cleaning, occasional lens/window replacements, operator training, and any software/vision licenses. Good fume extraction reduces long-term costs.
