Details
This line adopts an integrated design of multi-station rotary indexing mechanism + matched spraying unit + segmented curing system. It is tailor-made for the round shape and complex local structures of fuel lids, realizing full 360° spraying, stable film thickness and high yield. Compatible with solvent-based and water-based coatings, it meets A-class appearance standards for passenger cars and new energy vehicles, and is an efficient, space-saving solution for mass production of fuel lids.
Core Differentiation
- Linear forward movement only, no independent workpiece rotation. Hard to spray inner grooves, back sides and hidden gaps of circular fuel lids; frequent leakage and uneven film on edges. Long overall line length, large floor occupation, low utilization for small round parts.
Our Rotary Paint Line
Adopts turntable rotary indexing structure. Workpieces rotate synchronously at fixed stations to achieve double-sided & full-perimeter coverage without blind spots. Compact layout reduces floor space by over 40%. Each station completes dedicated process step by step, with higher production density for small round auto parts.
VS Ordinary Single-Station Rotary Spraying Equipment
Common Single-Station Rotary Equipment
Only supports spraying procedure, no integrated pretreatment, flash-off and curing functions. Processes are separated manually, leading to secondary dust pollution and unstable quality. Simple speed control, easy to cause paint sagging on curved surfaces of fuel lids.
Feature And Advantage
1. Dual Rotation Design for Full Coverage
Combines turntable indexing and workpiece self-rotation. Cooperated with multi-angle fixed spray guns, it completely solves the spraying difficulty of circular outline, inner grooves and back sides, realizing 100% coverage without blind spots.
2. Space-saving Integrated Rotary Layout
All processes are concentrated on one rotary turntable. Compared with linear lines, it greatly reduces floor area, lower requirements for workshop site and infrastructure.
3. Fuel Lid Dedicated Non-blocking Fixture
Custom clamps avoid shielding key spraying areas. Combined with matched rotation speed and airflow, paint accumulation and sagging in narrow grooves are fundamentally eliminated.
4. Low-temperature Gradient Curing Anti-deformation Technology
Abandon high-temperature baking. Segmented heating ensures thorough curing while protecting thin plastic fuel lids from warpage and deformation.
5. High Cost Performance & Easy Operation
Simple mechanical structure, low failure rate and low maintenance cost. No complex robot programming. Ordinary operators can master operation quickly, ideal for long-term mass production of single or similar parts.
Wide Compatibility
Supports solvent-based paint and water-based paint. Adapt to plastic, zinc alloy and aluminum alloy fuel lids, compatible with gloss, matte and metallic painting processes.

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.
