Hot Melt Roll Coater with Synchronized Dual Rollers & Nip Compression – Customizable for Textile/Foam/Insulation

This customizable roll coater is a continuous coating system that applies precise layers of paints, adhesives, functional coatings, or hot melts onto flat or flexible substrates. Available in industrial wide-format, laboratory roll-to-roll, and hot melt configurations.

The system is fully customizable in coating width, roller configuration (2-roll / 3-roll / reverse roll), drying modules, and automation level. The roller coating method is suitable for large-area sheet and strip coating, offering high efficiency and ease of achieving continuous production.

Working principle: The coating is picked up by the applicator roll from the pan and transferred to the substrate. In reverse roll coating, the applicator roll rotates opposite to the substrate direction, providing better shear control and enabling ultra-thin, uniform coatings (down to 1-2 µm). This method is widely used for architectural paint on coil metal, thermal coatings, adhesives, and specialty optical applications.

• Woodworking & panels: Furniture, cabinets, decorative boards, MDF, plywood coating - primer & finishing coat painting
• Metal processing: Pre-painted metal coils, corrosion-resistant coatings, architectural coil coating
• Packaging industry: Barrier coatings (moisture/oxygen resistance), heat-seal layers, adhesive primers
• Flexible electronics & optics: Conductive layers, functional films, OLEDs, solar cells - slot die and gravure methods available
• Textile & flooring: Carpet backing, foam lamination, non-woven fabric coating
• Automotive & construction: Carbon fiber products, insulation panels, adhesive tapes
• Adhesive application: Hot melt or cold glue application for lamination

This roll coater is highly customizable to meet your specific production requirements:
