III. Technical Overview

1. Basic Principles

• The equipment uses infrared radiation to directly heat the coating, rapidly reaching the curing temperature and allowing molecular crosslinking to form a durable coating. Infrared radiation has strong penetration, provides uniform heating, and ensures fast curing.

2. Core Process Flow

•  Powder Spraying

• Electrostatic Spraying: Uses electrostatic adsorption to evenly apply powder onto the workpiece surface.

• Fluidized Bed Spraying: Suitable for small workpieces, where powder adheres evenly using a fluidized bed process.

•  Infrared Preheating

• Preheating: Uses infrared radiation to preheat the workpiece, allowing the powder to begin melting, preparing for the curing process.

•  Infrared Curing

• Curing: Under infrared radiation, the powder fully melts and cures, forming a uniform coating.

• Temperature Control: Ensures proper curing temperature and duration to avoid under-curing or over-burning.

•  Cooling

• Natural Cooling: Workpieces cool naturally in the air.

• Forced Cooling: Cooling is accelerated using fans or a water-cooling system.

IV. Technical Advantages

• Rapid Heating: Infrared radiation penetrates the powder coating directly, enabling fast heating and reducing curing time, increasing production efficiency.

• Uniform Heating: Infrared radiation ensures even heating across the surface, preventing localized overheating or under-curing and guaranteeing consistent coating quality.

• Energy Efficiency and Environmental Protection: High heating efficiency with minimal energy loss, reducing overall energy consumption and operating costs while minimizing exhaust emissions.

• Precision Control: Intelligent control systems precisely regulate temperature and curing time, ensuring a stable curing process and improved product quality.

• Strong Adaptability: Suitable for various materials and complex-shaped workpieces, offering high production flexibility.

• Easy Maintenance: Modular design simplifies maintenance and component replacement, lowering maintenance costs and downtime.
