Phenolic Sandwich Panel Production Line

The phenolic sandwich panel production line as the core equipment for modern building insulation material production, integrates technologies from multiple fields such as mechanical manufacturing, chemical processes, and automation control. This production line is specially used to produce composite plates with phenolic foam as the core material and color steel plate, aluminum foil or non-woven fabric as the surface material. Its products are widely used in industrial plants, cold storage, clean workshops and other fields by virtue of their excellent fire resistance and thermal insulation effect.

The phenolic sandwich panel production line is a specialized production system integrating machinery, chemical industry and automatic control. It is mainly used to manufacture sandwich panels with phenolic foam as the core and metal or non-metallic materials on both sides. This type of production line uses a continuous process to mix phenolic resin with various additives for foaming, and firmly bond it with the upper and lower surface materials, ultimately forming composite boards with excellent fire resistance and insulation performance. From the composition of the production line, a typical phenolic sandwich panel production line includes multiple functional modules such as raw material pretreatment system, automatic feeding system, foam injection system, laminating molding system, curing cooling system, and cutting and stacking system. Each module is coordinated and operated through precise automation control to ensure production efficiency and product quality stability.

Phenolic sandwich panel production lines are mainly divided into two categories: continuous production lines and intermittent production lines. The continuous production line adopts the flow operation mode, which has high production efficiency and is suitable for mass standardized production. The continuous production line of phenolic foam exterior wall fire insulation board can produce 1000-1500 square meters per day. Intermittent production lines adopt segmented production methods with high flexibility, suitable for small batch and multi variety production, and can flexibly adjust production processes according to customer needs. These two types of production lines each have their own advantages, and users can choose the appropriate equipment type according to their own production needs.

The technical core of the phenolic sandwich panel production line lies in its modular design concept and automated control system. Advanced production lines usually adopt a modular structure design, where each functional module can operate independently and seamlessly connect. This design not only facilitates equipment maintenance and process adjustment, but also enables compatible production of multiple types of boards. By replacing different molds and adjusting process parameters, the equipment can produce various sandwich panels with thicknesses between 20-100mm and surface materials such as aluminum foil, non-woven fabric, or kraft paper, fully reflecting the flexible characteristics of modern production lines. In terms of control technology, modern phenolic sandwich panel production lines generally use PLC (Programmable Logic Controller) combined with touch screen human-machine interface. Some high-end equipment is also equipped with remote monitoring and fault diagnosis systems. For example, Sinowa's polyurethane/phenolic insulation board production line adopts an integrated linkage control system, which realizes centralized control and real-time adjustment of the entire line parameters, greatly improving the stability and controllability of the production process.

As a complex production system, the phenolic sandwich panel production line consists of multiple key equipment, and each link plays a decisive role in the quality of the final product. Understanding the functions and technical parameters of these core devices is of great significance for production line selection and process optimization. From the preparation of raw materials to the formation of the final product, each device on the production line is responsible for a specific function, and the coordination and cooperation between the devices ensure the continuity and stability of the production process.

Modern production lines are usually equipped with multiple discharge machines, which can simultaneously process different surface materials such as color steel plates, aluminum foil, non-woven fabrics, etc. Adapt to the production needs of products of different specifications. The phenolic composite board production line has specially designed non-woven fabric feeding device and automatic glue coating system. By adding non-woven fabric transition layer between color steel plate and phenolic foam, the bonding strength and yield of products have been significantly improved. The technological progress of the feeding device is mainly reflected in the automatic correction system and tension control technology, which ensure the positional accuracy and stability of the surface material during high-speed transportation, providing a good foundation for subsequent processes.
