If the wavelength is properly matched, a UV dryer machine will achieve fast drying speed, strong coating adhesion, and a smooth, glossy surface; conversely, problems such as incomplete surface drying, sticky surface, and insufficient hardness may occur.

In traditional drying methods, such as natural drying or hot air drying, coatings may take a long time to fully cure. However, in paint spraying production lines using UV dryer machines, the coating can cure in a much shorter time under UV light.

Furniture factories commonly use paint dryers, which can be categorized into hot air, infrared, and UV types. The corresponding lamps can be broadly classified as follows: • Ultraviolet lamps (UV lamps) • Infrared lamps (IR lamps) • Halogen lamps • Quartz heating tubes • LED ultraviolet lamps (UV LEDs)

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.

Furniture Manufacturing Industry In furniture production, many board surfaces require coating treatment. Some furniture production lines use UV coatings and are therefore equipped with UV dryer machines.

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.

In furniture coating production, the automatic spray painting machine is the core equipment for "painting," while the UV dryer machine is the core equipment for "curing." The two complement each other functionally, forming a complete automated coating system.

• The suitable paint film thickness range for furniture UV dryer machines is 5μm to 80μm. • The optimal curing range is 15–50μm, balancing gloss, hardness, and curing efficiency. • Thick films (>60μm) require high-power metal halide lamps or LED-395nm light sources, combined with low-speed conveyor transport.

UV dryer for furniture coating Recommended configuration: • Small furniture line: 2-3 lamps • Medium-sized production line: 3-4 lamps • Large automatic roller coating line: 5-6 lamps (multi-stage curing)

Common engineered wood types suitable for UV dryer machines: • MDF (Medium-density Fiberboard) • UV-coated panels • Particleboard • Melamine-coated panels • Plywood
