UV Curtain Coating Line

UV curtain coating lines are widely used across industries such as home furnishings, building materials, and decorative glass, offering significant advantages, particularly for achieving high-gloss coating effects and single-pass thick coatings on flat substrates.

Efficient and Eco-Friendly UV Curtain Coating Line

The UV curtain coating line is an automated industrial coating system characterized by high efficiency, precision, environmental friendliness, ease of operation, and low maintenance.

It combines advanced technologies, including one-time thick paint application and UV curing, to achieve a high-gloss visual effect. The high hardness of the UV paint effectively protects the substrate or printed patterns, while saving paint drying time, significantly increasing production capacity. Products can be packaged and shipped directly after this coating line, without delay.

The UV curtain coating line uses environmentally friendly liquid paint circulation technology, avoiding pollution and respiratory harm. It’s ideal for manufacturing furniture, floor, building materials, glass, and electronics.

The Workflow of UV Curtain Coating Lines is as Follows:

  • Materials Feeding: We typically use manual labor or automatic loading machines to perform this task.
  • Surface Treatment: The methods for surface treatment differ depending on the material. For example, we will sand and dust solid wood to achieve a consistent thickness and a spotless surface.
  • Primer Roller Coating: We apply one or more primer layers by roller coating based on material characteristics to increase coating thickness and adhesion, ensuring a solid foundation for the topcoat.
  • Topcoat UV Curtain Coating: When the curtain coating machine is operating, paint flows down the blade like a waterfall, and the workpiece is evenly coated with a thick layer as it moves forward, producing a gorgeous topcoat.
  • UV Leveling: Heating promotes paint leveling and prevents coating defects, such as waviness, bubble, and orange peel.
  • UV Curing: UV coatings 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: After topcoating, we can use machines to automatically cover protective film, stack products, or make other preparations for shipment.

Curtain Coating Machine

The curtain coating machine draws the liquid paint from the paint box into the precise knife bit and down like a waterfall as the materials pass through the paint curtain on the conveyor at high speed. This separate structure will deliver a better, more even coating.
