Sandwich Panel Line

As a leading manufacturer of sandwich panel production lines, we offer a comprehensive and fully automated system designed to meet the diverse needs of the construction and insulation industries. Our production line integrates advanced technology to ensure high efficiency, precision, and quality in the manufacturing of sandwich panels.

1. Decoiler System

The decoiler system is the starting point of our production line, designed to uncoil and feed metal coils into the subsequent processing units. Our hydraulic decoiler ensures smooth and controlled feeding, accommodating various coil sizes and weights. This system is crucial for maintaining a steady and uninterrupted production flow.2. Roll Forming Machine

Our roll forming machines are engineered to shape the metal sheets into the desired profiles for sandwich panels. Equipped with precision tooling and adjustable settings, these machines can produce a wide range of profiles to meet specific design requirements. The roll forming process ensures uniformity and consistency in panel dimensions.

3. Pre-Heating Unit

The pre-heating unit prepares the metal sheets by heating them to optimal temperatures. This step is essential for enhancing the adhesion properties of the panels and ensuring the effective bonding of the core material. Our pre-heating systems utilize advanced heating technologies to achieve uniform temperature distribution across the sheets.

4. Foaming and Injection System

Our foaming and injection system is designed for the continuous production of high-quality polyurethane (PU) or polyisocyanurate (PIR) foam cores. The system accurately mixes and injects the foam between the metal facings, ensuring consistent density and thickness throughout the panel. This unit is critical for achieving the desired thermal insulation properties of the sandwich panels.5. Double Belt Pressing Machine

The double belt pressing machine applies uniform pressure and heat to the sandwich panel assembly, facilitating the curing process of the foam core. This step ensures strong adhesion between the core and the metal facings, resulting in durable and stable panels. Our pressing machines are designed for high efficiency and consistent performance.

6. Cutting System

Our cutting system includes advanced band saws capable of precise and clean cuts. The system is synchronized with the production line to perform flying cuts, allowing for continuous operation without interruptions. This ensures that the panels are cut to the required lengths with minimal waste.

7. Cooling Conveyor

After cutting, the panels are transferred to the cooling conveyor, where they are allowed to cool and solidify. This step is vital for maintaining the structural integrity and dimensional stability of the panels. Our cooling conveyors are designed to handle high volumes and provide efficient cooling to the panels.

8. Stacking and Packaging System

The stacking system automatically arranges the cooled panels into stacks, ready for packaging. Our packaging system then wraps the stacks with protective materials, ensuring safe handling and transportation. These systems are designed for high throughput and minimal manual intervention, enhancing overall productivity.

Each unit in our sandwich panel production line is meticulously engineered to work in harmony, ensuring a seamless and efficient manufacturing process. We are committed to providing our clients with state-of-the-art equipment that meets the highest standards of quality and performance.

1. Fully Automated Production System

Our continuous sandwich panel production lines are equipped with a fully automated system that integrates various stages of production, including decoiling, roll forming, foaming, lamination, cutting, cooling, stacking, and packaging. This automation minimizes human intervention, reduces labor costs, and ensures consistent product quality. Advanced PLC control systems and digital servo technologies facilitate precise control over the entire production process.

2. High-Speed and High-Capacity Output

Designed for large-scale operations, our production lines offer high-speed capabilities, with adjustable production speeds to accommodate varying project requirements. The continuous nature of the line allows for uninterrupted production, significantly increasing output and meeting the demands of large construction projects. 

3. Advanced Foaming and Laminating Technology

Our production lines incorporate high-pressure foaming systems that ensure precise mixing and injection of foam materials, achieving uniform density and thickness across panels. The double belt laminating system applies controlled pressure and heat, facilitating the curing process and ensuring strong adhesion between the foam core and metal facings.

4. Precision Cutting and Sizing

Equipped with automated cutting systems, our production lines provide precise and clean cuts to the desired panel lengths without interrupting the continuous operation. This capability allows for high customization, accommodating various panel sizes and specifications to meet diverse construction needs.

5. Efficient Cooling and Stacking Systems

Post-production, panels are transferred to cooling conveyors that ensure uniform cooling, preventing warping and maintaining dimensional stability. Our automated stacking systems then arrange the cooled panels efficiently, readying them for packaging and shipment, thereby optimizing the overall workflow. 

6. Energy-Efficient and Environmentally Friendly Design

Incorporating energy-saving features, our production lines utilize advanced insulation technologies and efficient heating systems to minimize energy consumption. Additionally, the use of environmentally friendly foaming agents aligns with global sustainability standards, reducing the ecological footprint of the manufacturing process.

7. Customization and Versatility

Our production lines are designed with flexibility in mind, capable of producing a wide range of sandwich panels with varying core materials such as polyurethane (PU), polyisocyanurate (PIR), mineral wool, and expanded polystyrene (EPS). This versatility allows manufacturers to cater to diverse market demands, from cold storage facilities to residential and commercial buildings.

8. Integrated Quality Control Systems

To ensure the highest standards of quality, our production lines are equipped with integrated quality control systems that monitor parameters such as foam density, panel thickness, and adhesive application in real-time. Automated fault detection and parameter adjustments help maintain consistent product quality throughout the production cycle. 

By incorporating these advanced features, our continuous sandwich panel production lines provide manufacturers with the tools needed to produce high-quality, cost-effective, and customizable panels that meet the evolving needs of the construction industry.
