color coating line
The printing production line of colored steel plate is a complete of production equipment for colored steel plate
The printing production line of colored steel plate is a complete of production equipment for colored steel plate, and the process is as follows: make the steel coil strips be subject to surface degreasing, parkerising and passivating treatment, then apply multi-layer organic coatings (e.g., coatings of modified resin (SMP), high weather-resistant polyester (HDP), polyvinylidene fluoride (PVDF) etc.) on the strip surface by means of continuous roller coating, next, overprint multi-color patterns, and finally compound to form new functional plates. The production line is composed of equipment of uncoiler, sewing machine, tension machine, storage machine, degreasing and washing unit, roller-coating machine, printing machine, curing furnace, shear, coiler etc..
