- Minimum line width 0.015mm — sharper than chemical etching
- Up to 10,000mm/s linear scan speed
- Fully enclosed laser cabin — Class-1 safety
- Air-cooled · no chiller · no maintenance
Still etching pad printing plates with chemicals?
Traditional photochemical etching is slow, dirty, and expensive. Every batch means film exposure, acid corrosion, washing, and drying — plus the ongoing cost of consumables and environmental compliance.
- Multi-step process: film → exposure → acid etch → wash → dry
- 15-20 minutes per plate — slow turnaround for urgent orders
- Ongoing consumable costs: film, photoresist, etching acid, rinse water
- Chemical waste requires special disposal — environmental compliance burden
- Inconsistent depth and edge quality — plates need secondary finishing
- Complex designs and fine text often lose detail in the etching process
- Health risk for operators exposed to chemical fumes
- One-step digital process: import file → laser engrave → done
- High-speed galvo scanner at 10,000mm/s — plates done in minutes
- Zero consumables — no film, no acid, no photoresist
- No chemical waste — clean, dry, environmentally friendly
- Consistent depth with burr-free, smooth edges — ready for the pad printer immediately
- 0.015mm minimum line width — full design fidelity for fine text and complex logos
- Fully enclosed laser cabin — safe for operators, meets occupational health standards
Optical pump source → Q-switched pulse → scanned beam
The RSD-M200 uses an internationally advanced optical pump technology. Photons from the pump source excite the laser medium, and the Q-switch releases them as 1064nm high-peak-power pulses. A galvanometer scanner and F-θ lens direct each pulse into the steel surface.
Why a fiber laser?
1064nm wavelength light is strongly absorbed by metal surfaces, which means most of the energy goes into vaporizing steel instead of bouncing off. The RSD-M200 uses an industry-leading JPT fiber laser source with M² < 1.3 — a near-perfect TEM00 beam.
The result: a focused spot under 20µm in diameter, with a divergence angle only one-quarter that of a semiconductor-pumped laser. That beam quality is what allows 0.015mm minimum line width and the clean, burr-free edges the M200 is known for.
Seven reasons production lines choose the RSD-M200
Built around a JPT fiber laser and high-reliability galvanometer scanner, the RSD-M200 delivers precision, stability and zero-maintenance operation for pad printing plate production.
Integrated Structure with Auto Focus
One-piece frame with an automatic focusing system. The operator loads the plate and the machine finds focal distance — no manual adjustments, no trial-and-error.
Imported Isolator Protects the Laser
An imported optical isolator shields the fiber laser window from back-reflection damage. Stability and laser source life are both extended — the M200 runs reliably for years without service.
Beam Quality M² < 1.3 · TEM00
Far superior to traditional solid-state lasers. Focused spot under 20µm, divergence angle one-quarter that of semiconductor-pumped lasers. Purpose-built for fine, precision etching.
1/10 the Power of Lamp-Pumped Lasers
High electro-optical conversion efficiency. The entire machine draws under 800W — one tenth the energy of a lamp-pumped solid-state marker. Big savings on every monthly electricity bill.
Zero Maintenance
No consumables, no alignment drift, no daily service tasks. Long service life in harsh workshop environments. Just plug in, load the plate, and run.
One-Click Automatic Operation
Import your design file, click start. The machine runs the entire engraving cycle automatically. Anyone on the production floor can be trained to operate it in under an hour.
Fully Enclosed Laser Cabin
All laser processing happens inside a closed safety enclosure, raising your factory's safety production level and meeting occupational health requirements.
Auto-Encode Serial Numbers & Dates
The control software automatically codes serial numbers, batch numbers and dates. Perfect for traceability marking on regulated products.
Universal Software Compatibility
Compatible with AutoCAD, CorelDRAW, Photoshop and other design tools. Import PLT, BMP, DXF, AI files directly. Uses SHX and TTF font libraries — no conversion headaches.
