A powder coating production line for steel drums is a complete finishing system used to clean, pre-treat, coat, cure, and cool steel drums with a durable powder finish. It’s commonly used for industrial drums, oil drums, chemical drums, and decorative metal drums. Typical process flow1. Loading / Feeding - Steel drums are loaded onto a conveyor or hanging line.2. Pre-treatment - Degreasing / alkaline cleaning - Water rinsing - Phosphating or nano-ceramic coating - Drying - This improves adhesion and corrosion resistance.3. Powder Spraying - Electrostatic powder spray guns apply powder evenly to the drum surface. - Can be manual, automatic, or combined.4. Powder Recovery - Oversprayed powder is collected by cyclone + filter system and reused.5. Curing Oven - The coated drum passes through a curing oven, where powder melts and crosslinks. - Typical curing temperature: 180–200°C - Typical curing time: 10–20 minutes depending on powder type and drum thickness.6. Cooling - Air cooling or cooling tunnel before unloading.7. Inspection / Packing - Check coating thickness, adhesion, gloss, and appearance.
