Fireproof Rock Wool Sandwich Panel Machine

Sep 2, 2025

The fireproof rock wool sandwich panel machine is a specialized equipment used for producing fireproof rock wool sandwich panels. Through a highly automated continuous production process, metal panels are combined with rock wool core materials to form building panels with excellent fireproof, thermal insulation, and sound insulation properties.

Classification of Large and Small Machines

  • Small machine: suitable for producing shorter boards (usually of smaller length), with strong flexibility, suitable for small batches or customized needs.

  • Large scale machinery: specially designed for long boards, with high production efficiency, suitable for large-scale production, such as industrial plants, logistics and warehousing, and other large-span building needs.

Core equipment composition

  • Uncoiler and forming machine: used for unwinding and forming metal panels (galvanized sheet, stainless steel sheet, etc.) to form two layers of steel plates.

  • Rock wool cutting machine: Cut the entire rock wool into uniform strips, with fibers arranged vertically to enhance mechanical properties.

  • Double track press: a core composite equipment that tightly binds steel plates, adhesives, and rock wool through high pressure and heating.

  • Edge sealing system: Polyurethane foam or metal edge sealing strips are used to treat the side edges, improving fire sealing performance.

  • Cutting and palletizing system: Flying saws or synchronous tracking cutting saws achieve precise sizing, while palletizing machines complete sheet stacking and plastic packaging.

Production process flow

  • Raw material preparation
    Metal panels: Color coated steel plates, aluminum zinc coated plates, etc. with a thickness of 0.3-0.8mm, formed by rolling.
    Rock wool core material: high-quality rock wool with a density of 120-150kg/m ³ and an acidity coefficient of ≥ 1.4, ensuring fire resistance and durability.

  • Composite process
    Glue spraying and paving: Steel plates and rock wool strips form a sandwich structure of "steel plate glue rock wool glue steel plate" through an automatic glue spraying system.
    High pressure heating curing: The double track press applies uniform pressure while heating to accelerate the curing of the adhesive, with a production line speed of 20-30 meters per minute.
    Cooling shaping: Forced air cooling or natural cooling zone stabilizes the shape and bonding strength of the board.

  • Post processing
    Edge sealing: Polyurethane foam is used to fill the gaps at the edges, or metal strips are riveted and reinforced.
    Cutting and packaging: Cut to the required length and cover with PVC protective film to prevent transportation damage.

Technical features and advantages

  • The PLC control system realizes full process automation, the dual vibration defoaming device improves the compactness of the board, and the polymer roller ensures a smooth and wear-resistant surface.

  • Fireproof, thermal insulation and sound insulation, with overall stiffness better than on-site composite panels, can reduce the amount of purlins used.

  • Support customized parameters (width, color, plate shape, etc.), suitable for scenarios such as steel structure factories and clean rooms.

Application Fields

  • Industrial building enclosure

  • cold storage

  • clean room

  • mobile home

The fireproof rock wool sandwich panel machine has achieved large-scale production of high-performance building materials through precision design and automation control, becoming an important support for modern building energy conservation and safety protection.
