Machine details
A CO2 laser marking machine works at 10.6 um, in the far infrared. Non-metals such as wood, leather, acrylic, paper and fabric absorb 10.6 um extremely well, so the energy is taken up almost entirely at the surface and converted to heat - which is why marks are fast and edges are clean. Metals, by contrast, reflect most of this wavelength, so bare metal is generally not a candidate without a coating or spray.
The ZY-CO2 uses an RF (radio frequency) laser source. Compared with a traditional glass CO2 tube, an RF source delivers a better beam mode, faster pulse response and longer service life, and it supports high pulse repetition rates. High frequency matters because it keeps pulse overlap uniform even at high scan speeds, so the mark does not show light and dark banding - the baseline requirement for online coding on food and pharmaceutical packaging, where consistency is non-negotiable.
On performance: depth to 3 mm, minimum line width 0.05 mm, air cooled and maintenance-light, with 30 W, 60 W and 100 W options. 30 W suits shallow marking and high-speed coding on cartons and leather; 60 W balances engraving with thin-sheet cutting; 100 W handles thicker stock and faster lines. One machine covering both marking and cutting is why many advertising-letter, lighting and craft workshops choose this configuration.
The boundary is worth stating: CO2 performs poorly on bare metal. For stainless steel and aluminium alloys choose fiber; for ultra-fine internal engraving in glass or wafer marking choose UV. Each wavelength has its own job - there is no single machine that does everything well. Send your samples and we will tell you which wavelength fits your material, which is the most valuable step in our free sampling service.

Every point below is a checkable fact, not an unprovable promise.
- High-speed galvanometer scanning: fast, strong interference rejection, and a stable mark path over long runs.
- Integrated frame with high rigidity; changing a job means editing parameters, not dismantling the machine.
- Non-contact processing: no tool wear, clean and permanent marks that do not fade.
- Software imports DXF / PLT / BMF / AI / JPG artwork, editable on the PC before marking.
- Batch import from TXT / Excel, with automatic serial numbers, production dates, QR codes and barcodes.
- No consumables and low maintenance cost; the optical module is an industrial part whose service life is defined by its datasheet.
- Quiet operation with virtually no dust, suitable for 24-hour continuous running (a constant-temperature chiller keeps energy output stable).
- 10.6 um CO2 laser is the most cost-effective marking route for plastics and wood.
- 30 / 60 / 100 W options, with honeycomb fume extraction and filtration for shop-floor use.

Buyer questions
When engraving bamboo and wood gifts, how do you control edge charring?
Charring comes from heat accumulation: the longer the dwell time per unit area and the more concentrated the energy, the heavier the carbonization. Three controls: raise scan speed, lower power percentage, widen hatch spacing, and use air assist to carry away fumes and heat. Moisture content also matters - wetter wood darkens more. The ZY-CO2 RF tube keeps pulses uniform at high speed, which is key to consistent charring; run a gradient coupon to find the optimal parameter window for your wood.
For leather craft engraving, can CO2 handle complex patterns?
Yes. At 10.6 um the leather vaporizes in a controlled way, producing relief depth and tonal shading; a grayscale bitmap reproduces complex patterns in one pass with no screen printing or stamping die. The key is keeping energy below the point of perforation while keeping pattern edges crisp. Genuine leather and PU absorb differently, so parameters must be tuned separately. With a 0.05 mm line width the ZY-CO2 renders fine texture - send a real hide and we will return a sample video showing depth and feel.
For precision marking on clear acrylic, CO2 or UV?
It depends on the finish you want. CO2 is fast on acrylic, gives a frosted white mark, suits large-area back engraving and cutting, and costs less. UV is a cold process with finer edges and no heat-stress haze, better when optical clarity and ultra-fine lines matter. If you also need to cut acrylic sheet, one CO2 machine covers both; for haze-free precision engraving choose UV. We can sample both on the same sheet for comparison.
Can a CO2 laser mark bare metal directly?
Generally no. Bare metal reflects most 10.6 um energy and absorbs little, so coupling is poor: marks come out shallow and uneven with low throughput, and back-reflection risks damaging the optics. For metal use a 1064 nm fiber machine. If CO2 must be used on metal, apply a dedicated marking spray or anodising first - the mark forms through the coating bonded to the substrate.
