Rolling Composite Board Production Process

​Composite board, also known as sandwich panel, is a type of building material widely used in construction due to its excellent properties, such as sound insulation, heat insulation, fire resistance, etc. The production of composite board involves several steps, which we will discuss in this article.
 
Step 1: Preparation of Raw Materials
 
The first step in the production of composite board is the preparation of raw materials. This involves selecting the appropriate type of insulation material, such as polyurethane foam or mineral wool, and the outer skins, such as steel or aluminum. The thickness of the insulation material and the skins also need to be determined based on the desired properties of the composite board.
 
Step 2: Glue Application
 
The next step is to apply adhesive to the surfaces of the outer skins. This adhesive will bond the skins to the insulation material, creating a strong and durable composite board. The adhesive must be applied evenly and consistently to ensure the proper bonding of the materials.
 
Step 3: Assembly
 
After the adhesive has been applied, the outer skins and insulation material are placed together in an assembly line. This assembly line consists of rollers and presses that firmly compress the materials together, creating a stable and secure bond.
 
Step 4: Cutting and Trimming
 
Once the composite board is assembled, it is then cut and trimmed into the desired shape and size. This is done using specialized cutting equipment that ensures a clean and precise cut.
 
Step 5: Surface Treatment
 
The final step in the production of composite board is surface treatment. This involves applying a protective coating to the surface of the outer skins to improve their durability and longevity. The coating can be a paint or a specialized treatment that resists damage from weather and other environmental factors.
 
In conclusion, the production of composite board is a complex process that involves careful selection of materials, precise application of adhesive, and specialized equipment for cutting and trimming. The end result is a high-quality building material that offers excellent properties and meets the most rigorous standards of the construction industry.
