Common direct causes of uneven paint thickness include: • Unstable paint output from the spray gun; • Improper spray path spacing settings; • Mismatch between spray angle and workpiece surface; • Uneven spraying speed; • Poor paint atomization quality; • Inadequate equipment maintenance.

Under standard operating conditions (uniform spray width, optimized reciprocating path, continuous workpiece conveying), the spraying speed of a CNC automated painting machine is typically 200–600 square meters/hour. High-end multi-spray gun models, combined with intelligent path planning algorithms, can even exceed 800 square meters/hour.

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.

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.
