Typically, the paint utilization rate of curtain coater machines can reach 95%–98%.
In contrast, the paint utilization rate of automatic spraying machines is usually between 60%–85%, far lower than that of curtain coater machines.
Generally speaking, under the same working conditions, the color-changing time of a curtain coater machine is typically 15-40 minutes, shorter than that of a spray painting machine (which usually takes over 60 minutes) and simpler than a multi-roller coating system.
The curtain coater machine is not a "universal device." It is more suitable for continuous, flat, and flexible material coating processes.
For three-dimensional workpieces or irregular surfaces, traditional spray coating still offers greater flexibility.
