Colour Marking Bench Platform
Desktop MOPA Laser Marking Machine
A 20W to 100W JPT MOPA marker in a mobile bench cabinet. Adjustable pulse width turns stainless steel into a colour palette, while the same source delivers deep black marks on metals and clean codes on coated materials — all inside a Class 1 enclosure.

MOPA Advantage
Why MOPA Prints Colour on Stainless
A Q-switched fiber laser has a fixed pulse character. A MOPA source lets you shape the pulse, and that control is exactly what produces colour instead of a grey mark.
Shaped Pulses
The MOPA architecture separates pulse width from repetition rate, so the heat delivered to the surface can be tuned instead of fixed.
Controlled Oxidation
On stainless steel a thin oxide layer forms at the surface. Its thickness sets the colour, so the beam controls hue rather than just contrast.
Black Without Additives
The same source produces deep black marks on stainless and other metals, with no ink, film or coating involved.
Repeatable Recipes
Once a colour is approved, the pulse and frequency settings are saved as a recipe, so the next batch starts from the same result.
Colour & Black Marking Chart
The Colour and Black Marking Chart
The references below are produced on stainless steel coupons, the same way we would prove a recipe for your part before production.
01
Warm Tones
Longer, lower-energy pulses build warmer shades on stainless steel, useful for premium branding and decorative detail.
02
Cool Tones
Shorter, denser pulses push the oxide toward cooler shades, giving a second family of colours from the same machine.
03
Deep Black
At high overlap the surface turns a solid, durable black, which is the choice for data plates and machine-readable codes.
Parameter Control
Pulse Width Is the Colour Dial
Two settings do most of the colour work: how long each pulse lasts, and how closely the pulses are spaced across the surface.
- Pulse widthChange the duration and the heat delivered to the surface changes, which shifts the oxide thickness and the colour.
- Frequency and overlapSpacing the pulses closer darkens the mark, while wider spacing holds the colour lighter.
- Power headroomThe 100W model covers deep black work and fine colour detail in the same cabinet, so one machine serves both jobs.
- Stored recipesApproved settings are named and saved, which keeps a colour consistent between operators and shifts.
Key Numbers
Four Power Steps, One Compact Cabinet
All four models share the cabinet and the 65 kg frame. Power and beam quality are what change across the range.
100WTop rated MOPA power
300mmLargest marking area
65kgNet weight, all models
24VDC supply voltage
Computer Display Control
A clear interface and generous storage keep the workstation organised and the operator focused on the job.
Mobile Cabinet
Castors and a 65 kg frame let the unit be repositioned quickly, which suits a shop that changes layout often.
Aluminium Work Table
The table spreads heat and resists corrosion, which keeps part location stable through long colour runs.

Colour output depends on the material and its surface finish, not on power alone. Recipes are proved on a coupon of your own stainless steel before the machine is specified. EZCAD3 support is available on selected versions for 2.5D relief work.
Colour Workflow
From Colour Trial to Production Run
Colour marking is a recipe-based process. These four steps are how a shade moves from a test coupon to a repeatable production part.
01
Mark a Coupon
Run a grid of pulse widths and frequencies on the actual material and finish you will mark in production.
02
Select the Shade
Compare the grid against the approved colour and note the pulse width and frequency that produced it.
03
Save the Recipe
Store the settings under a job name so the same colour can be recalled without repeating the trial.
04
Repeat in Production
Load the recipe, mark the batch and check the first and last parts against the approved coupon.
Class 1 Enclosure
Closed, Interlocked and Bench Ready
The MOPA source runs at a power that would be a hazard in the open. In this cabinet it never is, which is what makes the bench format practical.
Sealed Beam Path
The beam stays inside the enclosure for the whole job, so no protective goggles are needed while the door is closed.
Emergency Stop
A single button cuts power and halts the machine, protecting both the operator and the workpiece in an emergency.
Demand-Only Scanner Power
The controller powers the galvanometer only when it is needed, which lowers energy draw and reduces wear on the scanner.
“We wanted a colour logo on stainless without paint or a sticker. The MOPA cabinet gave us a repeatable shade straight from a saved recipe, and the same machine marks the black traceability code next to it.”

FAQ
Desktop MOPA Marking: Common Questions
A MOPA marker has better pulse dynamics than a Q-switched fiber laser. Each mark is more precise, and the finished appearance on the material is of higher quality.
The machine is built for durability with very low maintenance, but for best performance we recommend periodic checks and cleaning of the lens, the galvanometer and other parts.
We supply a full user manual and training videos that walk through setup and operation. Our support team also offers video demonstrations and remote assistance by WhatsApp, WeChat and email.
A standard machine usually ships within 3 to 5 days. Machines customised to a specific requirement take 7 to 10 days.
Yes. It can be integrated into an automated production line, which suits high volume environments that need consistent output.
Yes. It marks colour on metals such as stainless steel. By adjusting pulse width and frequency a range of colours can be produced, adding value and customisation options.
It covers metals such as stainless steel, aluminium and titanium, plus plastics, ceramics and coated materials, which suits many industries.
Yes. The interface is intuitive, so even operators new to laser marking can use it. Basic training from SP is recommended so operators work safely and effectively.
Yes. Every desktop MOPA machine carries our standard warranty covering manufacturing defects, together with technical support and repair service.
It is compatible with advanced marking software such as EZCAD, which supports design work, parameter adjustment and integration with several file formats.
