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.

For general decorative panels If the furniture panel is only used for ordinary decoration (such as back panels, drawer bottoms, partitions, etc.), one roller coating is sufficient to form a basic protective layer and a gloss layer. In this case, spray painting is not necessary.

Yes, but certain conditions must be met. The core advantage of a UV roller coating machine lies in its high-precision coating control and surface smoothness. If the base coat's formulation, viscosity, pigment dispersion, leveling properties, and roller parameters are properly adjusted, a uniform coloring effect can be achieved.

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

The roller gap determines the actual amount of paint transferred and is the primary inspection item. • Normal gap range: Generally between 0.05–0.20 mm (depending on the process); • Adjustment method: Use a feeler gauge to measure the gap.

Depending on the product type and coating requirements of different companies, a furniture roller coating line typically requires 8 to 15 machines to form a stable and efficient production system. The key equipment required for each process will be analyzed below.

UV roller coating machines have high requirements for coating viscosity, typically controlled between 20 and 40 seconds. If the viscosity is too high, a special thinner can be added appropriately (do not use ordinary solvents) to improve leveling and help expel air bubbles.

In most normal temperature (20~25℃) production environments, the UV Roller Coating Machine usually does not require long-term preheating. The temperature difference between the machine's metal parts and the environment is not significant, and the fluidity of the UV coating is within a reasonable range.

In high-end applications, such as piano lacquer panels, automotive parts, or high-gloss furniture, the spraying precision of CNC automatic spraying machines can reach within ±0.1mm, while the coating thickness control error can typically be controlled within the range of ±3 to 5μm. This level far exceeds the capabilities of manual painting.
