10W UV Laser Marking Machine - JPT Seal-355-10S Water-Cooled Production Workhorse
Five Reasons This Machine Earns Its Place On The Shop Floor
Cold Marking, No Thermal Damage
A 355nm UV photon has roughly three times the energy of a 1064nm fiber photon, so it breaks molecular bonds on contact instead of heating material until it burns. The result is crisp permanent marks on silicone wristbands, medical catheters, PCBs with live components nearby, golf balls, heat-shrink tubing, and pharmaceutical packaging without melting, scorching, or warping anything around the mark zone.
JPT S-Series Source, Not E Economy
Haotian only ships S-series JPT UV lasers. The S-grade unit hits M² ≤ 1.2 (compared to ≤ 1.25 on the E economy) with tighter beam circularity and better long-term power stability under heavy production load. The difference shows up in the quality of small-font marks on cases and panels, and in how the laser holds output over a full shift instead of drifting.
Water Cooled For Continuous Duty
Water cooling is not a nice-to-have on a 10W UV laser, it is what separates a unit that runs all day from one that thermally throttles after an hour. The Seal-355-10S specifies a 500W cooling capacity requirement, and the machine ships with a matched industrial chiller that keeps the DPSS crystal at operating temperature through shift after shift. Sealed optics also block dust ingress that plagues air-cooled UV lasers.
Clean Beam For Micro-Marking
A 0.55mm beam diameter with TEM00 spatial mode and ≤2 mrad divergence delivers the tight focus needed for datamatrix codes, serial numbers, and logos on small electronics, jewelry components, and medical parts. The ≤1.2 M² value means the beam focuses close to the diffraction limit, which is what makes fine text legible down to fonts that fiber lasers smear or blur on heat-sensitive substrates.
Sealed Integrated Architecture
JPT built the Seal-355 series as a fully enclosed opto-electrical unit with the drive electronics integrated into the laser housing, which gives it strong EMI resistance on noisy shop floors and eliminates the fragile cable runs that cause service calls on split-box designs. A built-in air self-purification system keeps the internal beam path clean even in high-humidity environments, which is how JPT guarantees long-term stability without constant recalibration.

The Six Questions Every UV Buyer Asks Us First
What This Machine Cannot Do
Honest limitations before you buy
- Cannot cut sheet metal. This is a marking and micro-processing laser. For sheet metal cutting, the CNC fiber laser cutter category is the right tool.
- Cannot do fast bulk metal engraving. A 60W or 100W MOPA fiber laser is 5 to 10 times faster on stainless, brass, and aluminum production runs.
- Cannot drill through glass. UV marks the surface of glass beautifully, but drilling through-holes in glass requires the JPT M8 series (120W M8 or 200W M8) with the G3 PRO 2.5D galvo and EZCad3 software.
- Cannot do color marking on stainless steel. That is a MOPA fiber laser capability. UV produces white, clear, or etched marks, not the blue-green-gold color palette MOPA fiber creates.
- Not for wood cutting or large-format wood engraving. A CO2 gantry machine is the correct tool for those applications.
If any of the above is a primary requirement, ask us at info@haotianlasers.com and we will direct you to the right machine in the Haotian range.
How The 10W UV S Compares Inside The Haotian UV Range
| 5W UV S | 10W UV S | 15W UV S | |
|---|---|---|---|
| Average Power | Greater than 5W | Greater than 10W | Greater than 15W |
| Cooling | Air cooled | Water cooled | Water cooled |
| Duty cycle | Light / intermittent | Continuous production | Heavy continuous production |
| Best for | Entry, small format | Professional workhorse | Maximum UV throughput |
| M² beam quality | ≤ 1.2 | ≤ 1.2 | ≤ 1.2 |
| Source grade | JPT S-series | JPT S-series | JPT S-series |
The 10W UV is the volume choice for shops running UV as a daily production tool. The 5W suits lighter workloads where air cooling is sufficient. The 15W is for shops that need maximum throughput on UV work and are processing high volumes of glass, PCBs, or medical parts every shift.

Frequently Asked Questions
Why does the 10W UV cost significantly more than a 100W fiber laser?
UV lasers use a fundamentally different and more complex source architecture. The 355nm wavelength is produced by frequency-tripling a 1064nm infrared beam through nonlinear crystals, which requires precision optics, active temperature control, and much tighter manufacturing tolerances than a standard fiber laser. The DPSS crystal itself is expensive, and the sealed integrated architecture adds further cost. You are paying for capability the fiber laser physically cannot provide, not for more of the same.
Do I need special ventilation for UV marking?
For most applications, standard shop ventilation is sufficient because UV marking releases very little fume compared to CO2 cutting or fiber engraving on some plastics. When marking certain plastics (ABS, PVC-free thermoplastics, coated materials), basic fume extraction to the outside or through a HEPA plus activated carbon filter is recommended. We can include a fume extractor with the order if requested.
How long does a UV laser source typically last?
A JPT S-series UV source in normal production use lasts 20,000 to 30,000 working hours before output drops below rated power. That is roughly 10 years of daily single-shift operation. Water cooling and the sealed architecture are both designed to extend this lifetime, which is why we do not recommend the E economy grade for shops planning to run the laser hard.
Can I use LightBurn instead of EZCad 2?
Yes. The machine ships pre-configured for EZCad 2 because that is the native software for the SG7110 galvo controller, but the laser is LightBurn compatible through the standard galvo controller interface. Most UV users stick with EZCad 2 for production work because the UV material library is more developed there, but LightBurn is a valid alternative if your shop is standardized on it.
What kind of electricity does it need?
The machine runs on standard single-phase power (110V or 220V depending on region) and draws less than 250W average during normal operation. The industrial chiller adds its own power draw which we document in the setup guide. A standard workshop outlet is sufficient for the laser head, and the chiller may need its own circuit depending on your panel layout.
Can I upgrade the marking field later?
Yes. The standard 110 x 110 mm F-theta lens can be swapped for larger field lenses (150 x 150 mm, 175 x 175 mm, 200 x 200 mm, up to 300 x 300 mm) at the cost of some edge resolution. Let us know the field size you need and we will ship the right lens, or you can order additional lenses later and swap them in minutes.
How do I test the UV laser before committing to an order?
We run sample tests in the Saginaw showroom for customers who want to see results on their actual materials before purchase. Mail us a sample at 6191 Sherman Rd, Saginaw, MI 48604 with a note describing the mark you need, and the US director will run the test and return the sample with photos and settings. There is no charge for this service on serious inquiries.
Warranty And Delivery
18-Month Full Warranty
Every Haotian UV laser ships with 18 months of full warranty coverage on the laser source, galvo, power supply, control board, and chiller. If any non-source component fails within the warranty window, we ship a replacement free of charge and the broken part stays with you. No return required for most parts. Source defects require return shipment for JPT manufacturer warranty service, and Haotian covers shipping both ways.
After the warranty expires, lifetime email support continues at info@haotianlasers.com. The support team includes engineers who built the machines, not a general helpdesk.
Free DDP Shipping
