The difficulties of e-coating and powder coating large workpieces lie in the conveying method, powder recovery and color change efficiency. Taizhou Yufeng Intelligent Equipment Co., Ltd. designed a gantry e-coating and powder coating booth system for large workpieces and powder coating workshops, balancing heavy load carrying, uniform coating and clean production.

Gantry conveying system

The gantry conveyor uses a traveling crane or pusher structure. Workpieces are hung and automatically conveyed through the pretreatment, e-coating, drying and powder coating stations. The gantry structure has high load capacity and suits large products. The conveying speed matches the cycle of each process section, and the dwell time of workpieces in tanks and booths is controlled accurately. The conveyor uses variable frequency speed control, and different products can set different process parameters.

Powder booth structure design

The powder booth is designed according to ventilation and recovery requirements. The booth body uses a modular structure with smooth wall panels for easy cleaning. The booth is equipped with automatic powder guns or manual powder coating stations, and the airflow design prevents powder from escaping. Powder recovery combines cyclone separation and cartridge filtration. Recovered powder can be reused to reduce waste. The booth is equipped with explosion-proof lighting and safety devices.

Color change design

Color change is the key to powder coating efficiency. The system uses quick-change powder hoses and guns with independent color change components. The color change flow is standardized, cleaning the booth and recovery system, and the color change time is controlled. For customers with many colors, multiple powder hoppers and guns are configured to shorten color change waiting.

Powder recovery and environmental protection

The powder recovery system collects overspray powder. Cyclone separation recovers most of it, and cartridge filters capture fine powder. The recovered powder is sieved and reused to reduce coating cost. Exhaust air is filtered and discharged to standard. The system is maintained regularly to ensure recovery efficiency and filtration performance.

Project planning points

When planning a gantry e-coating and powder booth system, provide the product size and weight, daily output, powder colors, coating standard and factory height. We design the conveying plan, tank layout, powder booth and recovery system, and calculate investment and operating cost.
