SIP Panel Cold Press Machine
This SIP panel cold press machine is core laminating equipment for SIP structural insulated panel production. It adopts hydraulic ambient-temperature pressing, working with the SIP glue spraying machine. After glue dispensing and stacking (face sheet + foam core + face sheet), the panel is fed into this machine for constant pressure holding, to eliminate air bubbles and ensure tight bonding before PUR adhesive curing.
It can run standalone or connect with conveyor, SIP glue applicator, roll forming machine and cutting saw to form a full intermittent SIP panel production line.

Face sheets:
OSB, MGO board, calcium silicate board, plywood, color steel sheet, aluminum sheet, FRP
Core material: EPS, XPS, PIR, PU foam, rock wool
Adhesive: 1-component PUR moisture curing glue (standard), 2-component PU glue (optional)
Final products: SIP wall & roof panels, caravan panels, refrigerated truck panels, modular house panels
Key Advantages
1. Uniform pressure distribution across full panel, less hollowing and delamination
2. Cold pressing without heating, no deformation or melting of EPS/XPS foam
3. Adjustable pressure and holding time, multiple glue recipes saved
4. Heavy-duty frame, stable for long-time continuous production
5. Side positioning function, minimize panel misalignment
6. Easy operation, low maintenance cost
Main Components
1. Heavy-duty frame: Welded frame with thickened H-beam / square tube, stress-relieved by aging treatment, no deformation under long-term pressure.
2. Upper and lower pressing platens: Thickened precision-machined flat plates with high flatness, ensuring uniform pressure over the whole panel and preventing panel warpage.
3. Hydraulic cylinder assembly: Multiple cylinders for synchronous pressurization with balanced pressure, equipped with synchronous valves to avoid tilting of the pressing platen.
4. Hydraulic power station: Consists of oil pump, motor, solenoid valve and relief valve; pressure is adjustable with overload protection.
5. Conveying & positioning tooling (optional): Roller / belt feeding table and four-side positioning stoppers for automatic panel alignment to prevent misalignment.
6. PLC + touch screen control system: Pressure setting, holding time, pressure relief delay, counting, fault alarm and recipe storage.
7. Safety protection: Safety light curtain, front & rear protective doors, emergency stop buttons, hydraulic overload protection and low-pressure alarm.
8. Output support rack (optional): Supports panels after pressing to prevent bending and collision of large panels during discharging.
Production Process
Panel loading → Positioning → Glue dispensing via SIP glue spraying machine → EPS/XPS core laying → Top panel lamination → Cold pressing & pressure holding by SIP cold press machine → Curing → Finished SIP panel inspection
