Core Advantages for Industrial UV Curing
1. 405nm UV Wavelength, Perfect Matching for Industrial UV Formulations
405nm ±5nm near-UV wavelength matches the absorption peak of widely used photoinitiators in UV resins, adhesives, coatings and printing inks.
Effectively suppresses oxygen inhibition to achieve complete surface curing, eliminating sticky residual surfaces;
Narrow spectral linewidth ≤4nm FWHM, no redundant stray light, reduces substrate thermal deformation caused by broadband heat radiation;
Suitable for transparent resin, colored coating, optical adhesive (OCA) and low-shrinkage industrial curing materials.
2. 100W High Fiber Output Power Improves Line Speed & Throughput
Genuine 100W CW optical power at fiber end with 0–100W stepless power adjustment. Compared with low-power 20–60W UV laser modules, it enables higher conveyor speeds (20–80 mm/s) and supports wider curing zones and thicker coating layers.
Built-in constant current driving scheme for stable long-term operation, suitable for continuous batch curing production. Consistent UV energy output helps maintain stable curing quality within production batches.
3. Bundled Low-OH UV Fiber, Uniform Energy Output
Adopts integrated bundled UV low-OH multimode silica fiber, single unit fiber core 150μm (bundle configuration), with anti-UV aging cladding. Features low transmission loss even under long-duration high-power UV irradiation;
Non-detachable integrated bundled fiber design. Optimized bundle arrangement realizes superior near-field energy uniformity after beam shaping; no power loss risks brought by repeated plugging;
Standard fiber length 2m, customizable from 1–15m with UV-resistant anti-kink metal sleeve. The laser host and curing head can be separately arranged to reduce heat transfer to workpieces.
Matched with external homogenizing optics, it generates ideal flat-top uniform illumination for strip or planar continuous curing.
4. Built-In Active Water Cooling Syste for 24/7 Mass Production
Equipped with integrated high-flow circulating water cooling system, designed for high heat load of 100W full-power continuous output.
Efficient heat dissipation stabilizes laser operating temperature under full load, restraining power attenuation induced by heat accumulation;
G1/4 leak-proof water connectors with flow monitoring. Automatic alarm and laser interlock cut-off will activate once cooling failure is detected to protect laser chips and fiber;
Fanless zero-noise design, prevents dust accumulation, suitable for clean workshop environments. MTBF ≥10,000 hours supporting non-stop automated curing lines.
5. Multiple Control Modes & Comprehensive Safety Protection
DC 24V wide input voltage (22–26V tolerance), compatible with mainstream industrial curing equipment control systems.
Supports multiple control modes:
High-frequency PWM modulation (1kHz, 0–100% duty cycle);
Built-in analog modulation (0–24V analog signal for continuous power adjustment);
RS485 Modbus RTU communication for remote parameter configuration, real-time status monitoring and laser on/off control.
Multi-protection circuits: over-temperature protection, over-current protection, over-voltage protection and reverse connection protection. Sealed IP54 anodized aluminum alloy housing with anti-vibration performance for automated production line vibration.
