SIP glue spraying machine
This SIP glue spraying machine is specially designed for manufacturing SIP (Structural Insulated Panels). It adopts precision servo metering and linear glue pouring technology, mainly for 1C-PUR moisture-curing polyurethane adhesive. The machine applies glue evenly on OSB, MGO board, calcium silicate board, then composite with EPS/XPS/rockwool foam core to form SIP structural insulated panels. It can work standalone or connect with conveyor, cold press / hot press to form a complete SIP panel production line.

Application - Panels:
OSB, MGO board, calcium silicate board, plywood, FRP, color steel sheet - Core material: EPS, XPS, rock wool, PU/PIR foam - Final products: SIP wall panel, SIP roof panel, prefab house panel, caravan panel, refrigerated truck body panel, clean room sandwich panel - Adhesive: 1-component PUR glue (standard), 2-component PU glue (optional)
Key Advantages
1. Cold lamination, no heating required
Adopts moisture reactive one-component PUR glue, curing at ambient temperature. No heating system, low power consumption, avoids OSB deformation and foam shrinkage, stable flatness.
2. High bonding strength, reliable structural performance
Gantry system applies uniform glue layer. Press provides stable even pressure, meeting structural load requirements for European & American SIP building systems, compatible with ETA / ASTM certification.
3. Modular configuration, flexible investment
Customers can buy separate gantry glue applicator or single cold press; or multi-station cycle press (2-station / 3-station / 4-station). Press stations work in rotation while gluing station keeps running for higher output.
4. Wide material compatibility
One line can produce OSB+EPS, OSB+XPS, MGO+PIR and other SIP panels by adjusting glue formula and parameters, for fire-rated, passive house and regular residential projects.
5. Optional high automation, labor saving
High-end version equipped with vacuum sucker loader, automatic conveyor and positioning system. Reduce manual handling and panel damage, 1–2 operators for normal running.
6. Integrated CNC post-processing for finished panels
Connect with CNC machining center to cut window & door openings, spline grooves, wiring channels. Panels are marked and cut per construction drawing, ready for on-site assembly.
7. Export-friendly design
Fits mature SIP building codes in Europe and North America. PUR adhesive meets EN15425. CE certification and voltage adaptation available for overseas clients.
Main Components
1. Precise glue dosage control, glue saving by 20%-35% vs manual rolling / brushing
2. Linear glue pouring, no glue mist, clean workshop
3. PUR heating & constant temperature system to avoid glue crystallization and blocking
4. Multiple glue recipes stored, quick change for different boards
5. Wide size customization, max width up to 2000mm
6. Easy operation, only 1-2 workers needed
7. Stable bonding strength, weatherproof & water resistant for construction SIP panels
Production Process
Panel loading → Positioning → Glue dispensing via SIP glue spraying machine → EPS/XPS core laying → Top panel lamination → Cold press / Hot press forming → Curing → Cutting → Finished SIP panel inspection
