The essential difference between a UV dryer machine and an infrared dryer lies in their energy action mechanisms. A UV dryer machine is a "cold light curing device" that does not rely on high temperatures; while an infrared dryer is a "thermal energy drying device" that relies on temperature transfer.

In a CNC automatic spraying machine, the flow rate is typically adjusted by an electronically controlled proportional valve or gear pump. The operator can input the target paint film thickness (e.g., 30μm, 60μm, etc.) in the control interface, and the system will automatically calculate the optimal parameters based on the spraying area and flow rate algorithm.

Theoretically, high-gloss curtain coating machines can use water-based paints, but certain conditions and equipment adjustments must be met. The key lies in the ability to consistently control the paint's flowability, drying speed, and gloss recovery.

For minor clogging, gently clean the nozzle orifice with a soft brush; for severe clogging, use an ultrasonic cleaner to remove tiny residues from the nozzle through high-frequency vibration. Never use steel needles or wires, as this may enlarge the nozzle orifice and disrupt the spray pattern.

Whether a curtain coating machine needs a UV curing machine depends on the coating system used. If the curtain coating machine uses UV-curable coatings, then a UV curing machine is necessary; if it uses thermosetting or air-drying coatings, a drying oven or natural drying line can be used.

A curtain coating machine is a device that applies coatings by utilizing the principle of a free-falling liquid stream. A roller coating machine, conversely, is a coating device that transfers paint onto a workpiece surface through mechanical contact.

Traditional furniture coating processes typically rely on methods such as hot-air drying or infrared radiation, which often require anywhere from several minutes to several hours to dry completely. In contrast, when using a UV dryer machine, the entire curing process can be completed in just a few seconds.

UV paint differs from traditional solvent-based or water-based paints; its viscosity characteristics, reactivity, and curing mechanism are more complex. Therefore, it must be used with a specially designed UV curtain coating machine.

The coating speed of a UV roller coating machine can be controlled by an automatic system, but manual calibration is still required. Automatic control ensures stability, while manual intervention is used for initial settings and error correction.

The UV roller coating machine is best suited for coating medium-sized furniture and decorative boards with a width of 800mm-1300mm and a thickness of 6mm-25mm. Within this range, the highest production stability and best coating quality can be achieved.
