Nowadays, UV roller coaters have gradually replaced traditional spray coating and hot-air drying roller coating equipment, and are widely used for surface coating of panels, decorative mouldings, silicon steel sheets and other profiles. Integrated with precision roller coating and UV light curing technology, Colorful UV roller coaters meet the requirements of high efficiency, stable coating quality and environmental protection, and are suitable for large-scale continuous coating of flat and slender special-shaped workpieces.
1. Ultra-fast Curing & High Production Capacity
The machine delivers far higher curing efficiency than conventional coating equipment. Based on UV ultraviolet light curing principle, paint films can be fully cured within seconds after roller coating. It eliminates lengthy hot-air drying and natural air-drying procedures. Finished workpieces can be stacked and transported directly without paint adhesion issues. Equipped with a frequency-conversion synchronous conveying mechanism, the conveying speed is adjustable on demand. The production line supports 24-hour non-stop operation, which greatly shortens production cycles and boosts overall output.
2. Stable Coating Accuracy & Few Surface Defects
It adopts a matched dual-roller structure consisting of metering roller and coating roller. Operators can precisely control film thickness by adjusting roller gap and rotating speed, achieving uniform coating layers. Common coating defects including orange peel, sagging, missing coating and paint accumulation on edges can be effectively avoided. The machine supports single-sided and simultaneous double-sided roller coating, which perfectly covers grooves and side edges of skirting lines and silicon steel sheets. It outperforms traditional spray coating in both paint film adhesion and surface flatness.

3. Eco-friendly & Cost-effective Operation
Matched with solvent-free UV coatings with nearly 100% solid content, the equipment generates extremely low VOC emissions and leaves no pungent odor in workshops, fully complying with environmental inspection standards.The closed paint supply structure removes the need for large waste gas spraying booths, lowering investment in plant space and waste gas treatment.
4. Strong Versatility & Easy Maintenance
The machine is fitted with a PLC touch control system with storable process parameters, which lowers operation difficulty for workers. The solvent-resistant rubber rollers feature excellent corrosion resistance and long service life, only requiring routine post-shift cleaning. It is compatible with multiple substrates including solid wood, PVC, metal and MDF, and satisfies diversified coating demands for primer, high-gloss topcoat and matte topcoat.
