The XBS-920BS Hot Melt Glue Machine for Foam represents a breakthrough in foam bonding technology, addressing the critical challenge of preventing foam degradation during adhesive application. Unlike standard hot melt machines that use excessive heat, this specialized system features a foam-optimized heating range (80-130°C) that activates adhesives without melting or distorting cellular structures. Its 15L stainless steel tank supports a 16kg/hour melting capacity, making it ideal for medium to large-scale production of foam-based products. The machine’s precision dispensing technology delivers adhesive beads as fine as 0.5mm, ensuring strong bonds without visible glue residue—essential for upholstery and packaging applications where aesthetics matter .
A digital PID controller maintains ±1°C accuracy within the 80-130°C range, the optimal temperature window for EVA and PSA hot melts used in foam bonding. Overheat protection automatically engages at 140°C to prevent foam scorching.
A specialized gear pump delivers 1.2-2.5 bar pressure, reducing foam compression during application while ensuring sufficient adhesive penetration into porous structures. This reduces material waste by 25% compared to high-pressure systems .
Teflon-coated foam-specific nozzles with 0.5mm-3mm adjustable orifices prevent adhesive buildup, even when using viscosity-sensitive foam adhesives. Quick-change nozzle cartridges reduce downtime during material switchovers.
Perfect for bonding polyurethane foam to fabric, leather, and wooden frames in sofas, mattresses, and automotive seating, providing flexible bonds that withstand repeated compression.
Ideal for assembling foam inserts, protective packaging, and thermal insulation materials, ensuring consistent bonding without compromising cushioning properties.
Used in soundproofing panels and studio acoustic treatments, bonding porous foam layers with minimal material penetration that would reduce sound absorption.
What adhesive types work best with this machine?
Use EVA-based hot melts with 90-110°C melting points for polyethylene foam and PSA formulations for polyurethane foam applications. Avoid high-temperature adhesives exceeding 130°C melting point.
How to prevent adhesive penetration in low-density foam?
Activate the reduced flow mode and use the 0.5mm nozzle with pressure set to 1.2 bar. This creates a shallow bonding layer that stays within the foam’s surface layer.
What maintenance prevents nozzle clogging?
Flush the system daily with foam adhesive cleaner and use the auto-purge function after each shift. Replace nozzle filters every 100 hours of operation to remove foam particulate buildup .
