High-Precision Automated Scraper Coating Line for Demanding Backer Board Applications

This integrated line is engineered for continuous, high-quality surface coating of extrusion backer boards. The standard configuration comprises: Unwinding Station → Precision Pre-cleaning System → Scraper/Comma Coating Head → Multi-Zone Drying Oven → Cooling Section → Automatic Thickness Gauging System → Rewinding Station. The line is controlled by a centralized PLC with HMI touchscreen. Customization options include adding a primer coater, UV curing module, embossing unit, or integrating with upstream extrusion output.

Our High-Precision Automated Scraper Coating Line is designed to apply uniform, defect-free coatings (e.g., protective layers, primers, decorative finishes) onto extruded polymer-based backer boards used in construction, signage, and composite panels. It ensures consistent coating weight, excellent adhesion, and high production yield through precise automation and process control.

This line is ideal for applying functional or aesthetic coatings onto:

• PVC, WPC, HDPE Extrusion Backer Boards
• Building Facade and Cladding Panels
• Signage and Display Boards
• Furniture and Interior Decorative Panels

We specialize in tailoring solutions to your specific needs. Key customizable aspects include:

• Coating Method: Scraper (doctor blade), comma coater, or roller coater head
• Drying/Curing: Infrared, UV lamp, or hot air convection systems
• Automation Level: From semi-automatic to fully automated with robotic handling
• Integration: Designed to seamlessly connect with your existing extrusion or cutting lines

• Precision Coating Head: Micrometer adjustment for exceptional thickness control
• Automatic Tension Control: Ensures stable web handling and prevents deformation
• In-line Thickness Monitoring: Real-time feedback for consistent quality
• Energy-Efficient Oven: Optimized airflow design reduces energy consumption
• User-Friendly Interface: Simplifies operation, maintenance, and recipe changes

We provide comprehensive support: Installation & Commissioning Supervision, On-site Operator Training, 12-Month Warranty on Machinery, and Lifelong Technical Support. Detailed operation and maintenance manuals are provided. Spare parts are readily available.

The line is disassembled into major functional modules for safe transport. All components are securely packed in wooden cases with waterproof and shock-absorbing materials. We handle all export documentation (Packing List, Commercial Invoice, Bill of Lading) and can arrange shipping to your nearest port (FOB, CIF, or DAP terms available).
