Sinowa's non hydraulic servo lifting mechanism can accurately control the thickness of the sheet (10-200mm), avoiding leakage and maintenance problems of traditional hydraulic systems. Realize parameter linkage, fault self diagnosis, and remote control through the main control center, reducing manual intervention. For example, the energy consumption of the entire line is only 40% of similar products, and the heating system can reach the process temperature within 1 hour when the room temperature is above 5 ℃. Supporting pentane or 141B foaming media, flexibly adapting to the high-pressure foaming needs of 2-9 component polyurethane, improving environmental friendliness and economy (pentane foaming system).

The steel structure exterior wall sandwich panel production line adopts a fully enclosed internal insulation design, without the need for additional insulation rooms, supporting all-weather production. Some devices use thermal recycling technology to reduce energy consumption and comply with green building standards.

Core equipment composition

• Compression molding unit: Cold bending technology is used for processing color steel panels, suitable for scenarios such as building curtain walls and roofs.
  

• Layering machine: The aluminum chain plate laminating system achieves continuous composite of core material and panel, ensuring bonding strength.
  

• Fixed cutting system: laser or servo sawing equipment with an accuracy of ± 1mm, supporting processing of up to 15 meters of sheet metal.

Process adaptability

• Surface treatment: Supports various surface materials such as color steel, aluminum foil, non-woven fabric, etc., to meet decoration and functional needs.
  

• Fire resistance performance: The rock wool sandwich panel has a fire resistance limit of 240 minutes, and the polyurethane panel achieves B1 level fire resistance by adding flame retardants.

Expansion of application areas

• Green building: The demand for prefabricated steel structure buildings has surged, and the proportion of sandwich panels in ultra-low energy consumption buildings has increased.
  

• Special scenarios: In cold storage, purification workshops, and other scenarios that require high sealing and insulation properties, PIR core materials or phenolic boards are used.
  

With the advancement of modular buildings and intelligent manufacturing, the production line of exterior wall sandwich panels will iterate towards higher integration and lower energy consumption, becoming the core link of the green building industry chain.
