Automatic Hot Melt Glue Machine
The GENMAX PJ2100 is a 6-head servo-driven hot-melt glue spraying machine for industrial mattress assembly. With laser auto-detection of foam dimensions, three selectable spray patterns, and a fully adjustable spread rate of 45–800 g/m², the PJ2100 completes a full glue application cycle — perimeter and center — in 30 seconds per layer, with no manual adjustment between sizes.

Specially Designed for Industrial Foam Hot-Melt Bonding
6-head servo-driven hot-melt glue spraying for foam, spring, latex, and felt mattress assembly. Laser auto-detection.
6-HEAD SPRAY SYSTEM
Six independent heads cover the full 2,100 mm width simultaneously — uniform adhesive coverage with no gaps, edge to edge, every cycle.
AUTO SIZE DETECTION
Laser sensors automatically measure foam length and height before every cycle — no manual input or changeover required between sizes.
FULL SERVO DRIVE CONTROL
All conveyor and spray gun movements are servo-driven for precise, programmable glue placement — consistent adhesive positioning at every point.
Ideal for High-Speed Industrial Foam Assembly
Hot-Melt Glue Spraying Machine
The PJ2100 feeds hot-melt bonded foam layers directly into downstream pressing and packaging stations — maintaining precise adhesive coverage across every layer and maximizing the throughput of complete mattress production workflows.

FAQs
What is the production throughput?
The PJ2100 completes a full glue application cycle — including automatic size detection, perimeter and center spraying, and conveyor transfer — in 30 seconds per layer.
How many spray heads does it have, and what patterns are available?
The PJ2100 has 6 spray heads covering the full 2,100 mm working width. Three spray patterns are selectable: strip, spiral, and bulk — allowing operators to optimize glue distribution for different mattress constructions. Both spray nozzles and bead nozzles are available.
What type of nozzle does the PJ2100 use?
The PJ2100 supports both spray nozzles and bead nozzles, selectable based on your production requirements. Spray nozzles provide wide-area surface coverage for full-layer bonding; bead nozzles deliver precise line application for perimeter and structural bonding.
What type of adhesive does the PJ2100 use?
The PJ2100 uses thermoplastic solid (granule) hot-melt adhesive — the industry standard for mattress assembly. It provides high bonding strength, fast set time, and clean application with no liquid mess or solvent odor.
Can the spread rate be adjusted?
Yes. Glue spread rate is fully adjustable from 45 to 800 g/m², accommodating everything from lightweight fabric bonding to heavy-duty foam layer assembly. Spray speed is also adjustable from 300 to 800 mm/s.
Does the machine detect foam sizes automatically?
Yes. The PJ2100 uses laser-based sensors to automatically measure the incoming foam or mattress unit's length and height before each spray cycle. Detection is immune to foam color sensitivity and electrostatic interference — no manual input or adjustment is needed between different sizes.
What Is The Warranty Period For Your Hot Melt Glue Machine?
We provide a standard warranty period of 12 months from the date of installation, covering any manufacturing defects and ensuring customer satisfaction.
What Is The Lead Time For Delivery After Placing An Order?
The lead time typically ranges from 30 to 90 days, depending on the model and order specifications. We will provide an estimated delivery date upon order confirmation.
Can I produce high-density memory foam with this system?
Yes. The combination of the 30kW high-performance motor and the 3000 RPM mixing head provides the necessary torque and mixing intensity to handle the higher viscosities associated with luxury memory foam and high-resilience (HR) grades.
