Printing Production Line of Colored Steel for GEIT

The printing production line of colored steel plate is 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..

Equipment Parameters:
