A color coating line is an automated production system used to apply colored or functional coatings to the surface of metal coils, such as steel, aluminum, and stainless steel. The finished products offer excellent corrosion resistance and an attractive appearance, making them widely used in construction, household appliances, and other fields.
| Production Line | Substrate Type | Process Speed (m/min) | Substrate Thickness (mm) | Substrate Width (mm) | Production Line Length (m) | Energy Medium | Process Flow |
| Pre-painted coil production line for home appliances | Galvanized / Aluminum-zinc / Zinc-aluminum - magnesium / Stainless steel | 20-120 | 0.3-1.5 | 700-1650 | 100-200 | Water / Electricity / Gas | Uncoiling → head cutting → riveting → deburring → entry looper → alkaline washing → brushing → hot water rinsing → conditioning tank → hot water rinsing → drying → chemical treatment → drying → cooling → primer coating → primer baking and curing → primer cooling → drying → finish coating → finish baking and curing → finish cooling → drying → exit looper → quality inspection → slitting → recoiling → packaging and storage |
| Pre-painted coil production line for construction panels | Galvanized / Aluminum-zinc / Zinc - aluminum - magnesium / Stainless steel | 20-250 | 0.1-1.2 | 700-1650 | 70-200 | Water / Electricity / Gas | uncoiling → head cutting → riveting → deburring → entry looper → alkaline washing → brushing → hot water rinsing → conditioning tank → hot water rinsing → drying → chemical treatment → drying → cooling → primer coating → primer baking and curing → primer cooling → drying → finish coating → finish baking and curing → finish cooling → drying → exit looper → quality inspection → slitting → recoiling → packaging and storage |
