Project Requirements
The client approached Foshan Happy Technology with the following key requirements:
1. Space Efficiency – The available factory floor space needed to be maximized, making a vertical spraying production line the most suitable choice.
2. High Throughput – The line should handle large daily production volumes without compromising coating uniformity.
3. Surface Quality – Achieve a flawless, durable finish on all aluminium profiles, suitable for both powder coating and specialized surface treatments.
4. Automation – Reduce manual handling to improve consistency, safety, and labor efficiency.
5. Energy Efficiency – Incorporate advanced curing systems and ventilation to minimize energy consumption and VOC emissions.
Our Engineering Solution
After a thorough site survey and discussions with Jinniu Aluminium’s production team, our engineers proposed a custom powder coating line based on a vertical conveyor system. This design included:
Automated Profile Loading Station – Reducing manual lifting and risk of damage.
Multi-Stage Pre-Treatment – Chemical cleaning, rinsing, and drying stations to ensure optimal adhesion.
Precision Powder Spraying Booths – Equipped with high-efficiency guns for uniform powder distribution.
Vertical Curing Ovens – Compact yet capable of rapid temperature stabilization, ensuring uniform curing.
Automated Unloading and Packaging Section – Streamlining the post-coating process.

Technical Highlights
1. Space-Saving Vertical Design
Unlike conventional horizontal lines, the vertical layout significantly reduces floor footprint, allowing for more efficient material flow and better space utilization in the factory.
2. High Precision Powder Application
The industrial spraying system utilizes advanced electrostatic guns with adjustable spray parameters, ensuring consistent coating thickness on complex aluminium profile shapes.
3. Advanced Control System
A PLC-based interface allows operators to select coating recipes, monitor production status, and receive real-time maintenance alerts.
4. Energy-Efficient Curing
The curing ovens use an optimized airflow system, reducing power consumption by up to 20% while ensuring uniform heating.
