What is sandwich panel line

Sandwich Panel Production Line is a specialized manufacturing system designed for the automated production of sandwich panels. Sandwich panels consist of two outer layers (often made of metal, plastic, or composite materials) and a core material (such as foam, polyurethane, mineral wool, or honeycomb structure) sandwiched between them. The production line typically includes various machines and equipment for continuous or batch production, such as:

1.Uncoiler and Coil Feeding System: To feed metal coils into the production line.
2.Roll Forming Machine: Shapes the outer metal layers into the required profile.
3.Gluing System: Applies adhesive or bonding material to the core and outer layers.
4.Panel Press: Presses the layers together to form the sandwich panel.
5.Cutting System: Cuts the sandwich panels to the desired length.
6.Cooling and Stacking Systems: Cools down and stacks the finished panels for further processing or shipping.

Characteristics and Applications of Different Types of Sandwich Panels

1. Polyurethane Sandwich Panels

Characteristics: Polyurethane sandwich panels offer excellent thermal insulation, lightweight properties, high compressive and tensile strength.

Applications: Mainly used for thermal insulation in building walls and roofs, insulation in cold storage facilities, and interior partition walls where high insulation performance is required.

2. Rockwool Sandwich Panels

Characteristics: Rockwool sandwich panels are known for their excellent fire resistance, thermal and acoustic insulation properties, high compressive strength, and corrosion resistance.

Applications: Widely used in building exterior walls and roofs for insulation, industrial facilities for sound and thermal insulation, and cold storage walls, especially in environments requiring high fire resistance.

3. Expanded Polystyrene (EPS) Sandwich Panels

Characteristics: EPS sandwich panels are lightweight, offer good thermal insulation, economical, easy to process and install, with moderate compressive strength.

Applications: Primarily used for thermal and acoustic insulation in buildings, interior partition walls, temporary structures, and prefabricated houses where lightweight and economical solutions are needed.

4. Fiberglass Sandwich Panels

Characteristics: Fiberglass sandwich panels feature excellent corrosion resistance, lightweight, high strength, and good insulation properties.

Applications: Mainly used for building exterior walls in corrosive environments, industrial equipment enclosures, interior decoration of ships, and other applications requiring corrosion resistance and durability.

5. Composite Metal Sandwich Panels

Characteristics: Composite metal sandwich panels are complex in structure, offering excellent structural strength, compressive strength, and durability.

Applications: Used in high-end building exteriors, structural components in aerospace, enclosures for special industrial equipment, and other applications requiring high structural strength and durability.


Different types of sandwich panels cater to various needs in construction, industry, and specialized applications due to their unique material compositions and properties. Choosing the right type of sandwich panel can significantly enhance building functionality, meet design requirements, and environmental demands.
