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.

UV Roller Coating Machines typically require paint viscosity within a certain range (e.g., 25–60 seconds/Ford-4 cup). If the viscosity is too low, the coating cannot form a stable film on the roller surface, and it tends to spread too quickly on the board, causing it to sag due to gravity.

The most common and highly compatible UV paints for roller coating machines include: UV primers, sealers, intermediate coats, high-gloss topcoats, matte topcoats, and clear acrylic systems.

Furniture coating requires high precision and consistency. Single-roller or double-roller structures often cannot meet the complex process requirements; therefore, most furniture factories choose multi-roller UV Roller Coating Machines.

A UV Roller Coating Machine in a furniture factory typically requires only 2-3 people to operate efficiently. Among them: • 1 person responsible for equipment control and process monitoring; • 1 person responsible for material feeding and receiving; • Depending on production volume, one additional person can be added for assisting with handling and inspection.

Coating machines, UV curing machines, and sanders are linked through an automated control system, maintaining a stable 24-hour production line cycle. However, it's important to emphasize that theoretical feasibility does not guarantee practical sustainability.

Step 1: Shut down the equipment and power system. Step 2: Drain the paint system. Step 3: Clean the roller surface. Step 4: Clean the scraper system. Step 5: Clean the paint tank and conveying system. Step 6: Clean the pipes and pump.

From a coating process perspective, a UV Roller Coating Machine is perfectly suitable for small-batch production, provided that the company correctly configures the equipment parameters and production process.

When the speed difference between the metering roller and transfer roller of a UV Roller Coating Machine is too large, shear bubbles can form in the coating layer. Especially under high-viscosity coating conditions, these bubbles are more difficult to escape, resulting in "pinhole" or "bulge" defects during curing.

Although theoretically UV Roller Coating Machines should not scratch furniture boards, in actual production, surface scratches, lines, or abrasions can still occur if the equipment or operation is improper.
