Continuous Production Line For Color Steel Sandwich Panels

The continuous production line of color steel sandwich panels is an efficient and automated production equipment, mainly used for the continuous production of sandwich panels with double-sided steel plates, aluminum plates, and intermediate sandwich materials such as polyurethane (PU) and rock wool. This production line has a wide range of applications in the building materials industry, capable of producing sandwich panels with light weight, high strength, and good insulation performance, meeting the diverse needs of the construction industry.

The continuous production line of color steel sandwich panels usually consists of multiple parts, including uncoiler, hydraulic shear, forming unit, laminating device, foaming unit, mobile pouring machine, preheating device, laminating conveyor, automatic tracking cutting machine, etc. These devices work together to complete the entire production process from raw material uncoiling, cutting, shaping, laminating, foaming, curing to cutting finished products.

The technical parameters of the continuous production line for color steel sandwich panels vary depending on the equipment model and manufacturer. Here are some common technical parameters:

• Production specifications for color steel sandwich panels: The width is usually between 700-1250mm, the thickness is between 30-300mm, and the length can be customized according to customer needs.
  

• Production line speed: generally between 3-8m/min, the specific speed depends on the configuration of the production line and the type of raw materials.
  

• Total installed capacity: Depending on the scale and configuration of the production line, it usually ranges from tens of kilowatts to hundreds of kilowatts.
  

• The maximum temperature of hot air circulation is generally between 70-80 ℃, used to heat the surface of metal plates and promote the curing of foaming agents.

The production process of color steel sandwich panels usually includes the following steps:

• Uncoiling and cutting: The uncoiler fixes and uncoils the color steel coil, while the hydraulic shear cuts the color steel plate to obtain the required size of sheet metal.
  

• Pressing and laminating: The pressing unit presses the color steel plate to form the desired plate shape. At the same time, the laminating device applies a thin film on the surface of the color steel plate to protect it and improve the performance of the sandwich panel.
  

• Foaming and curing: Inject foaming agent (such as polyurethane, rock wool, etc.) between the pressed color steel plates, and heat and press them together through a preheating device and a laminating conveyor to solidify the foaming agent and form a sandwich structure.
  

• Cutting and Finished Products: After foaming and curing, the sandwich panel enters the automatic tracking cutting machine and is cut according to customer needs to obtain the finished color steel sandwich panel.

Color steel sandwich panels have the advantages of light weight, high strength, good thermal insulation performance, and convenient construction, and are widely used in public buildings, industrial plants, large warehouses, large-span roofs and walls, and other fields. Meanwhile, according to different core materials and board types, color steel sandwich panels can also meet specific usage needs, such as fire prevention, waterproofing, sound insulation, etc.

With the continuous development of the construction industry and the increasing demand for building material performance, the continuous production line of color steel sandwich panels is also constantly innovating and developing. In the future, the production line of color steel sandwich panels will pay more attention to automation, intelligence, and environmental performance improvement to meet the market's demand for high-quality and high-performance sandwich panels.

The continuous production line of color steel sandwich panels is one of the indispensable and important equipment in the building materials industry. Through continuous optimization and innovation, this production line will provide the construction industry with more high-quality and efficient sandwich panel products.
