The excimer lamp surface finishing machine uses a 172nm excimer lamp (VUV) to cure ultra-thin coatings, creating a soft-touch, velvet-like, or matte surface on various substrates, including:
- Wood-based panels (MDF, particleboard)
- PVC / PET films
- Plastic sheets (ABS, PC, PMMA)
- Automotive interior parts
- Electronic housings
- Furniture and flooring materials
Unlike conventional UV curing, excimer technology achieves 100% matt finish (gloss level as low as 0-5 GU) without using matting agents. The process produces a micro-shrinkage surface that scatters light, resulting in an elegant soft-skin feel, anti-fingerprint properties, and high scratch resistance.
This system operates under inert nitrogen atmosphere to prevent oxygen inhibition, ensuring consistent curing quality. The entire line can be customized for flat panel, roll-to-roll, or 3D-shaped substrates.
We provide full customization for excimer lamp surface finishing lines:
- Working width: from 300 mm to 2200 mm
- Substrate type: flat panel, roll-to-roll, or shaped parts
- Lamp power and number of lamp units (single or dual excimer)
- Nitrogen flow rate and atmosphere control precision
- Coating method: roller coating, curtain coating, or spray
- Integration with existing UV line or printing line
- Fully automatic or semi-automatic operation
- Exhaust and ozone filtration level (for cleanroom environment)
- Custom GUI on PLC touchscreen (multiple languages)
- Explosion-proof configuration for solvent-based coatings
Q: What is the difference between excimer curing and conventional UV curing?
A: Excimer (172nm) creates a micro-shrinkage layer for ultra-matt and soft-touch effect, while conventional UV gives a glossy, hard finish. We can customize combinations of both.
Q: Can I add an excimer unit to my existing UV line?
A: Yes, we offer retrofit excimer modules that can be integrated into existing conveyor systems.
Q: What substrates are compatible?
A: Wood, MDF, PVC, PET, PP, ABS, PC, and even metal sheets with primer. The system is customizable for heat-sensitive films.
Q: Is nitrogen required?
A: Yes, nitrogen is essential to eliminate oxygen inhibition at 172nm. We supply a complete customizable nitrogen control system with low consumption.
Q: How is the soft-touch feel measured?
A: Subjective tactile evaluation + gloss meter (60° angle). Gloss below 5 GU typically correlates with a pronounced soft-feel effect.
