UV Spray Painting Line

UV spray painting lines are highly compatible and ideal for industrial mass production of various special-shaped products, including furniture, doors and windows, building wall panels, auto parts, special materials, and other applications.

Widely Applicable UV Spray Painting Line

The UV spray painting line is a fully automated, multifunctional, and widely applicable high-efficiency coating line. It effectively meets the automatic coating and drying needs of workpieces that require uniform color on all six sides or that feature grooves and decorative lines.

Fitted with top-tier components, including the GRACO medium-pressure mixed-air spraying system sourced from the United States, it incorporates advanced technologies such as dual-axis reverse spraying, a paint circulation system, an automatic conveyor belt cleaning system, and rapid UV paint curing. It reliably surpasses expectations in enhancing coating quality and production efficiency while also reducing paint consumption and labor expenses.

The Workflow of UV Spray Painting Lines is as Follows:

Materials Feeding: We typically use manual labor or automatic loading machines to perform this task.
Dust Removal: High-density anti-static brushes and air knives work together to remove stubborn dust and impurities from the workpiece surface, resulting in a cleaner, more flawless finish.
Reciprocating UV Spray Painting: Eight GRACO spray guns mounted on two horizontal axes reciprocate in opposite directions to evenly coat the workpieces, producing a smooth coating on both the surface and the four edges.
UV Leveling: Heating promotes paint leveling and prevents coating defects, such as waviness, bubble, and orange peel.
3D UV Curing: UV coatings on the workpiece’s surface and edges rapidly polymerize and crosslink under ultraviolet irradiation via photoinitiators, completing the curing process in just a few seconds and significantly reducing drying time.
Finished Products: Similarly, we can use manual labor or equipment to complete the unloading work. And after the UV spray painting line, the products can proceed directly to the next process without waiting.

Standard Configurations

Dust Collector

The dust collector uses a double anti-static brush, rotating it in different directions to remove dust, impurity and burr from the workpiece surface, then blows it again to ensure the surface is clean enough for the best coating effect later.
