UV Laser Marking Machine
The WH-5W is a desktop UV laser marking machine with a 355 nm wavelength and a JPT laser source, rated at 5 W. It marks with a minimum line width of 0.01 mm and a minimum character height of 0.2 mm, using a beam quality of M2 <1.2.
Product Overview
What This Machine Is Built To Do
The WH-5W is a desktop UV laser marking machine with a 355 nm wavelength and a JPT laser source, rated at 5 W. It marks with a minimum line width of 0.01 mm and a minimum character height of 0.2 mm, using a beam quality of M2 <1.2. The marking scope is 150 x 150 mm, with optional 110 x 110 mm or 175 x 175 mm fields. The machine uses water cooling, an EZCAD main board, and a high-speed galvanometer to place marks with ±0.003 mm repositioning precision. It is built for workshops that need ultra-fine marks on glass, ceramic, plastic, PVC, PCB and polymer parts without the heat deformation that longer wavelengths can cause.
- 355 nm UV wavelength produces a small focused spot for ultra-fine marks on glass, ceramic and plastic
- 0.01 mm minimum line width and 0.2 mm minimum character height support micro-marking on small components
- ±0.003 mm repositioning precision keeps serial numbers and barcodes aligned across repeated part loading
- JPT laser source rated at 10000 hours lifetime reduces the frequency of source replacement
- Genuine Beijing EZCAD main board supports rotation axis and needs no independent dongle
- Desktop form factor fits into industrial online production processes without a dedicated cell
Where It Is Used
Application Scenarios
- Electronics manufacturers marking serial numbers and barcodes on PCB boards
- Consumer goods producers printing dates and codes on plastic and polymer packaging
- Glass and ceramic workshops engraving logos and text on brittle substrates
- Pipe fabricators marking identification codes on PVC pipes
- Charger and adapter producers placing regulatory text on small housings
Buyer Fit
Who It Is For
- Electronics and PCB assembly shops that need low-heat marking on sensitive components
- Plastic injection moulders marking parts directly instead of using labels
- Glass and ceramic producers requiring fine engraving without mechanical stress
- Machine dealers who need a compact UV marker that fits desktop production lines
Process Problems
Problems It Solves
- Longer wavelength lasers can deform thin plastic and glass; the 355 nm spot reduces mechanical deformation
- Heat-affected zones from other marking methods are minimised by the UV process
- Manual alignment errors are reduced by ±0.003 mm repositioning precision on repeated loads
- Consumable costs disappear because UV marking produces no inks or abrasives
- Small character legibility is maintained with a 0.2 mm minimum height and 0.01 mm line width

Working Process
From File To Finished Part
Import PLT, JPG, BMP, PNG or DXF files into the EZCAD marking software
Set automatic encoding, serial number, date or barcode parameters in the software
Adjust the Z axis lift between 0 and 47 cm to focus on the part surface
Position the part within the 150 x 150 mm marking scope
Run marking at up to 10000 mm/s with the high-speed galvanometer
Verify mark depth and legibility against the 0.01 mm line width specification
Quality Control
Quality Control Before Shipment

Options
Customisation Options
- Choose marking scopes of 110 x 110 mm, 175 x 175 mm, 200 x 200 mm or 300 x 300 mm
- Select laser power of 3 W, 5 W or 10 W depending on marking speed requirements
- Configure rotation axis support for cylindrical parts
- Voltage and plug configuration set for your destination market
Comparison
How It Compares With The Alternatives
| Fiber laser marking machine | The UV 355 nm source marks glass and plastic with less heat deformation, but cannot mark copper |
|---|---|
| CO2 laser marking machine | UV achieves a smaller focused spot for 0.01 mm line width, but has a lower maximum power of 10 W |
| Inkjet coding | UV marking is permanent and wear-resistant without consumables, but requires line-of-sight access to the surface |
Operating Notes
Use Guide
- Do not use on copper, as the UV wavelength is not absorbed effectively by that material
- Check water cooling temperature before long runs to maintain stable light output
- Use the rotation axis for cylindrical parts like PVC pipes or charger housings
- Adjust Z axis lift to match part height, since focus distance affects minimum line width
- Keep the field lens clean, as dust on the optics degrades the small focused spot
