Details
UV Paint Line is a professional automated color spraying production system designed for UV base color painting, metallic color painting, and matte color finishing. Different from the UV Coating Line which focuses on high-gloss clear functional coating, this line is specially optimized for color uniformity, metallic flashing control, color difference management and full-tone coverage.
It supports mass production of various UV color paints, metallic paints, pearl paints and matte paints, widely used for two-wheeler parts, automotive plastic trims, home appliance housings and 3C appearance components. With electrostatic rotary atomizer spraying, precise IR color leveling and low-temperature UV instant curing, it realizes stable color consistency, high coverage rate and excellent surface texture in high-volume production..
Feature And Advantag
Standard Process Flow
Loading → Pre-cleaning → Surface Activation → Electrostatic Dust Removal → UV Primer Spraying → IR Leveling → UV Color Paint Spraying → Precision IR Color Leveling → UV Instant Curing → Cooling → Color Inspection → Rework → Unloading
1. Professional UV Color Tone Control System Optimized rotary atomizer speed and molding air parameters specially for metallic and pearl UV paints. Effectively solves common color defects such as floating color, mottle, metallic unevenness and light difference.
2. Low-temperature Color Locking Technology Adopts mild IR soft leveling + instant UV curing. No high-temperature baking, ensuringzero color shift and stable tone batch-to-batch.
3. High Hiding Power & Uniform Coverage Precision flow control and ultra-fine atomization ensure consistent film thickness, perfect hiding power and no substrate exposure for dark color series.
4. Strict Color Difference Control Stable dust-free & constant humidity environment eliminates color deviation caused by environment fluctuation, achieving mass production color difference ΔE ≤1.2.
5. Fast Color Change Structure Equipped with quick-clean paint circuit and automatic flushing system, color change time ≤15 minutes, suitable for multi-color mixed production.
6. Eco-friendly Low VOC Formula Adaptation Fully adapted to high-solid UV color paints, with extremely low VOC emission, meeting global environmental protection standards.

FAQ
Q: How do you guarantee our quality standards?
A: We layer in quality: offline robot programming optimizes spray paths first, SCADA logs every parameter (full traceability), and we can add automated vision checks for 100% surface inspection. One client matched their OEM's strict standards on the first try.
Q: How fast can you set up a car parts paint shop?
A: 3-6 months with modular parts.
Q: Does it work for EV production lines?
A: Yep, it's perfect for EV parts like BYD's, with eco-friendly coating.
Q: How much maintenance is needed?
A: Daily wipe-downs, quarterly checks. Downtime's under 2% with our support.
Q: Can it fit in a small factory?
A: Absolutely. We design compact layouts-even multi-level (mezzanine) setups to save floor space. Our 3D simulation lets you see the layout first, so we maximize output per square meter. A Guangzhou client with a tight space now runs 2 lines where they used to fit 1.
Q: Is this a fully unmanned, "lights-out" factory system?
A: While highly automated for minimal supervision, the system is engineered for operational excellence with strategic human oversight. Tasks like fixture loading, final quality audit, and system monitoring are essential for ensuring ultimate reliability and quality, creating a perfect synergy between automation and human skill.
