MOPA Fiber Laser Marker for Stainless Steel Color Coding

MOPA laser marking system has a more diverse application range, wider pulse width range and is more flexible than the conventional Q-switch platform. The adjustable pulse width can indirectly affects the peak power, allows MOPA laser marking system to mark on a wide variety range of materials with high contrast results, and vivid colors on stainless steels. Finer beam quality ensures the best marking results.

Overview


The MOPA Laser Marking Machine for Stainless Steel Color Marking is a specialized solution designed to create vibrant, permanent color marks on stainless steel surfaces using advanced Micro-Pulse Amplitude Modulation (MOPA) technology. Engineered to control oxidation depth with precision, it delivers high-contrast color coding for traceability, branding, and decorative applications.


Features


MOPA Laser Technology: 20W MOPA fiber laser with adjustable pulse width (10ns–20μs) and repetition rate (10kHz–80MHz), enabling precise control over oxidation layer thickness for consistent color formation.

Color Palette Generation: Produces up to 8 distinct colors (gold, blue, black, red, green) on 304/316 stainless steel without coatings or chemicals, with color fastness exceeding 500 hours of UV exposure.

High-Resolution Marking: 15μm spot size achieves 800dpi resolution for detailed logos, gradient color effects, and micro-text (0.5mm height) on 0.1mm² micro-areas.

Thermal Management System: Active air-cooling with temperature feedback (±1°C stability) ensures stable power output during 24/7 operation, preventing color inconsistency caused by thermal fluctuations.

User-Friendly Color Editor: Dedicated software with real-time color preview and presets for common stainless steel finishes (brushed, polished, bead-blasted), reducing trial-and-error time by 70%.


Application


Ideal for stainless steel-specific marking, this machine is used in:

Medical Instruments: Color-coding surgical tools (forceps, scalpels) with sterilization dates and batch numbers for quick identification in operating rooms.

Consumer Goods: Engraving brand logos and serial numbers on stainless steel watches, kitchenware, and luxury accessories with premium color effects for enhanced aesthetics.

Aerospace Components: Marking heat-resistant stainless steel parts with temperature-sensitive color codes (e.g., blue for high-temperature zones) for maintenance tracking.

Industrial Equipment: Creating corrosion-resistant color marks on valves, flanges, and pressure vessels in oil & gas and chemical plants for safety signage and asset management.


Why Choose Us


Color Marking Specialists: Our MOPA technology achieves industry-leading color consistency (ΔE ≤1.5) across large batches, surpassing traditional laser marking methods.

Process Control Mastery: Proprietary algorithms adjust laser parameters in real-time based on material reflectivity, ensuring 99.7% color uniformity even on curved or textured surfaces.

Compliance Assurance: Marks meet FDA 21 CFR Part 11 (medical) and NACE MR0175 (corrosion) standards, ideal for regulated industrial environments with strict material requirements.

Innovation Leadership: Continuously develop new color recipes for emerging stainless steel alloys (e.g., duplex stainless steel), future-proofing your marking operations.
