• Application : Double roller paint coating machine is used for the plain coating of primer and topcoat of interior and exterior wall panels, decorative panels, furniture, floors and cupboards.

A double roller coater is a coating equipment designed for applying uniform coatings onto flat material surfaces. It uses two sets of coating heads to complete the coating process, ensuring consistent coating thickness and eliminating uneven application, thereby improving product quality. This machine is especially suitable for large-area panels and strip materials such as flooring, cabinet boards, and furniture boards. It offers higher efficiency than a single‑roller coater and is compatible with materials including wood, glass, metal sheets, plastic films, melamine boards, and plywood.

• Excellent coating uniformity
  By utilizing the coordinated action of two coating rollers, the double roller coater applies coating evenly across the material surface. Coating thickness uniformity can achieve a tolerance range of approximately ±5% to ±10%, depending on equipment precision and operating conditions. This high uniformity is critical for applications demanding superior surface quality and coating performance, such as furniture finishing and automotive interior parts.

• Wide material applicability
  The machine can coat a variety of materials, including metal, wood, plastic, paper, and leather. By adjusting parameters such as roller material, pressure, and rotational speed, excellent coating results are achieved for different substrates. For example, metal rollers with higher pressure and speed are used for metal sheets, while rubber rollers with lower pressure are used for paper to prevent damage.

• High coating utilization
  Coating is transferred directly from the rollers to the material surface, minimizing overspray and dripping that occur with spraying methods. Coating utilization typically reaches 70% to 90%, reducing production costs and environmental pollution.

• High production efficiency
  The double roller coater enables continuous coating at relatively high speeds. Material conveying speed generally ranges from several meters to tens of meters per minute, satisfying large‑scale industrial production needs. It can be integrated with drying equipment, cutting machines, and other devices to form an automated coating production line.

1. Dramatically Increased Productivity: The double-roller design processes panels twice as fast as a single-pass machine for complex finishes. It reduces the number of required coating stages and handling steps, significantly boosting overall line output.

2. Unmatched Finish Quality & Consistency: Delivers a flawlessly smooth, uniform, and opaque coating layer completely free of streaks or color variation. The independent precision control of each roller is key to achieving this high-standard, repeatable result.

3. Superior Versatility for Complex Recipes: Enables innovative and efficient finishing processes by combining different materials (e.g., filler + primer) or effects in one continuous operation, offering greater flexibility for product finishing specifications.

4. Maximum Material Efficiency & Cost Savings: The fully enclosed recirculation system ensures virtually zero material waste. This leads to direct savings of over 50% in paint consumption compared to spray methods, providing a rapid return on investment.

5. Optimized for Demanding Applications: Excels at applying high-viscosity materials and building thick film layers in a single pass without sagging or imperfections, making it ideal for high-solid content coatings and sealing requirements.

• Wood: Wood flooring, furniture panels, blinds, flat doors, sauna boards – can be coated with varnish, color paint, or waterproof coatings to enhance aesthetics and durability.

• Plastic: Plastic films, decorative plastic panels, PVC rolls/sheets – can receive protective coatings, decorative coatings, or anti‑static coatings.

• Metal: Metal sheets, metal foils – commonly coated with anti‑corrosion paints, anti‑rust paints, or decorative paints for surface protection and appearance improvement.

• Other panels: Calcium silicate boards, cement boards – can be coated with fire‑retardant coatings, thermal insulation coatings, or decorative coatings; paper‑based panels can be varnished or coated with adhesives.

• Fabric: Natural fibers (cotton, linen, silk, wool) and synthetic fibers (polyester, nylon, acrylic) – used for dyeing, printing, or applying functional coatings such as water repellents, stain repellents, and UV blockers.

• Leather: Natural and synthetic leather – can be coated with leather conditioners, color enhancers, waterproof coatings, or abrasion‑resistant coatings to improve texture, durability, and water resistance.
