Color Coating Line Coating process description
Aluminum coil color coating line is developed according to the market demanding, which could implement simultaneously coating at both sides. According to the different needs of customers, it can finish single coating at one side, single coating at both sides, dual coating at top side while single coating at under side, dual coating at both sides in one time.
Color Coating Line General process flow
1#2# Uncoiler → steering pinch roller → steering roller →confluent pinch roller → inlet shear → sewing machine → press burr and pinch roller → 1# tension roller → inlet looper → 2# tension roller →degreasing → brushing → water washing → drying → chemical roller-coating machine → chemical-coating drying furnace → 1# deviation-correcting machine → 3# tension roller → initial coating unit → initial coating curing furnace → cooling unit → 2# deviation-correcting machine → dryer → 3# deviation-correcting machine → 4# tension roller → printing unit → fine coating unit → fine coating curing furnace → cooling unit → dryer → 4# deviation-correcting machine → 5# tension roller → outlet looper → 6# tension roller → pinch shear → steering roller → EPC deviation-correcting coiler → inspection → package → entering warehouse
