Automated spray coating delivers high-quality automotive topcoat appearance.
The spray booth in a paint shop is an enclosed or semi-enclosed space specifically designed for painting operations, serving the primary function of providing a stable and controllable coating environment. Situated between the pretreatment/electro-coating and drying stages, it is dedicated to the automated application of primer-surfacer and topcoat layers on vehicle bodies-in-white. Through processes such as paint atomization, trajectory control, and environmental adaptation, it ensures the formation of a uniform coating on the body surface; it is a critical piece of equipment for guaranteeing the vehicle's visual quality, weather resistance, and corrosion protection, thereby enhancing the product's overall competitiveness.

Function of Spray Booth
—— Provides a clean and stable painting environment, precisely controlling paint pressure, flow, and atomization pattern to ensure uniform film thickness.
—— Captures and treats overspray and VOC emissions, reducing paint mist diffusion and environmental pollution while improving working conditions.
—— Works with robotic spray systems to achieve even coating on complex areas such as curved surfaces, edges, and door frames.
—— Maintains stable temperature, humidity, and airflow to minimize solvent fluctuation and improve coating repeatability and product yield.
—— Enables paint recovery and recycling, reducing material consumption and supporting green, low-carbon production requirements.

Structural Characteristics of the Spray Booth
—— Composed of air supply system, exhaust and paint mist treatment system, spray operation area, exhaust gas treatment system, and lighting system.
—— Uses laminar air supply combined with downward exhaust airflow, creating a stable airflow field that effectively removes paint mist and solvent vapors.
—— Equipped with wet paint mist capture devices such as Venturi and water-rotary systems, or dry filtration systems, ensuring high removal efficiency.
—— Integrated with constant temperature and humidity control, airflow monitoring, pressure differential monitoring, and safety interlocking functions for stable process parameters.
—— Supports both robotic automatic spraying and manual touch-up spraying, enabling flexible mixed-model production.
—— Equipped with fire and explosion protection, automatic fire suppression, and emergency shutdown systems to ensure safe and stable operation.
