Equipped with multi-axis spraying robots, high-precision micro-atomization system, Class 8 dust-free environment and intelligent parameter database, the line realizes full-surface blind-spot-free spraying, stable color consistency and delicate surface texture. It supports solvent-based, water-based and UV paints, and meets high requirements of anti-fingerprint, matte, metallic and high-gloss finishes. As a core intelligent coating solution for the 3C industry, it adapts to multi-variety, small-batch and high-standard mass production.
Core Differentiation
- VS General Robotic Paint Shop: General robotic lines target large industrial parts; this line is miniaturized and refined for tiny 3C components, with stricter film thickness tolerance, higher dust-free grade and optimized robot trajectory for narrow gaps and curved edges.
- VS Fixed-Gun Paint Shop: Fixed guns cannot cover complex 3D surfaces of 3C parts; multi-axis robots achieve omnidirectional spraying, suitable for irregular, slim and cavity-structured electronic components.
- VS Ordinary UV / Water-based Automatic Lines: Conventional lines are designed for single process and single product; this robotic system stores dozens of product programs, realizing one-click switching between different 3C models and paint formulas.
- VS Automotive & Two-wheeler Dedicated Lines: Dedicated lines focus on large exterior parts; this shop prioritizes ultra-fine atomization, ultra-thin uniform film and zero micro-defects, complying with 3C high-end appearance inspection standards.

- High-precision Robot Trajectory Technology6-axis robot with ultra-high positioning accuracy, specially programmed for 3C complex structures such as curved edges, side walls, tiny holes and narrow gaps. Achieves 100% coverage without spraying dead zones, and keeps consistent spraying posture for every workpiece.
- 3C Dedicated Micro-atomization SystemOptimized low-pressure micro atomization structure produces fine and uniform paint mist. It forms an ultra-thin, smooth coating layer, effectively avoiding orange peel, grain and thick edge defects which are fatal for 3C appearance parts.
- Mass Program Storage & Fast Model SwitchingThe control system can store hundreds of sets of spraying trajectories, paint flow, air pressure and curing parameters for different 3C products. Realize one-click program switching, model changeover time ≤10 minutes, supporting frequent mixed production of multiple products.
- Full-process Ultra-clean Environment ControlAdopts high-grade dust-free booth and multi-stage air filtration. Combined with full-line static elimination, it drastically reduces micro-particle and pinhole defects, fully matching the zero-defect inspection standard of 3C electronic products.

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.
