Sandwich Panel Production Line
High-Efficiency Sandwich Panel Manufacturing Solutions
A sandwich panel production line is a fully automated manufacturing system designed to continuously produce insulated panels used in industrial buildings, cold storage facilities, clean rooms, and prefabricated construction.
Guangxing Machinery provides both continuous and discontinuous sandwich panel production lines, Our sandwich panel production lines support different core types (PU, PIR, rock wool), and can be configured per product requirements and local standards.

Continuous vs Discontinuous Sandwich Panel Production Lines
Continuous Sandwich Panel Production Line
The continuous sandwich panel production line is designed for manufacturers requiring high output and consistent quality. Panels are produced in a non-stop process, making it ideal for large-scale industrial production.
Key advantages:
- High production speed
- Stable continuous operation
- Excellent foam curing and bonding performance
- Suitable for PU, PIR, and rock wool panels
This configuration is commonly used in projects with strict delivery schedules and standardized panel specifications.
Discontinuous Sandwich Panel Production Line
A discontinuous sandwich panel production line operates in batch mode and is suitable for manufacturers producing customized or small-batch panels.
Key advantages:
- Flexible panel length and thickness adjustment
- Lower initial investment
- Easier operation for startups or regional factories
This system is ideal for manufacturers prioritizing flexibility over maximum output.
Main Systems of a Sandwich Panel Production Line
A complete sandwich panel production line consists of several key systems working together.
Coil Handling System
The coil handling system loads and feeds metal coils into the production line. It ensures stable sheet positioning and smooth material flow during continuous operation.
Functions:
- Automatic coil loading
- Precise sheet feeding
- Reduced downtime during coil change
Roll Forming System
The roll forming system shapes the upper and lower metal facings. Accurate forming ensures panel profile consistency and surface flatness.
Features:
- High-precision forming rollers
- Stable forming speed
- Compatible with various panel profiles
Foaming / Core Processing System
The foaming or core processing system forms the insulation layer inside the panel.
- For PU/PIR panels, a high-pressure foaming system injects and cures the foam core.
- For rock wool panels, a rock wool strip feeding and positioning system ensures uniform core density.
- For EPS panels, an EPS bead injection and molding system creates the insulation core.
This system plays a critical role in thermal insulation, fire resistance, and bonding strength.
Cooling, Cutting & Stacking System
After core processing, panels pass through cooling and cutting sections.
- Cooling stabilizes panel dimensions
- Flying saw or cross-cutting machines cut panels to precise lengths
- Automatic stacking systems organize finished panels for packaging
These systems ensure consistent panel size and smooth downstream handling.
Applications of Sandwich Panels
Sandwich panels produced by these lines are widely used in:
- Industrial buildings and warehouses
- Cold storage and refrigeration facilities
- Clean rooms and modular buildings
- Fire-rated wall and roof systems
Different core materials allow manufacturers to meet specific insulation, fire safety, and structural requirements.

Frequently Asked Questions (FAQ)
1. What types of sandwich panels can this production line manufacture?
This sandwich panel production line is designed for the production of PU, PIR, and rock wool sandwich panels. Panel thickness, width, and surface materials can be customized according to project requirements and local building standards.
2. Is the sandwich panel production line fully automatic?
Yes. The line operates automatically from coil feeding to panel stacking, reducing manual intervention.
3. What production capacity can this sandwich panel production line achieve?
Production capacity varies depending on panel type and configuration. Typical output ranges from medium-scale to high-capacity industrial production, and the line can be customized to meet specific annual output targets.
4. How many operators are required to run the production line?
Under normal operation, our continuous sandwich panel production line typically requires only 6–7 trained operators. The exact number may vary depending on the automation level, panel type, and auxiliary systems such as stacking and packaging.
5. What is the typical installation and commissioning time?
Installation and commissioning time depends on the line configuration and factory conditions. In most cases, mechanical installation, electrical setup, and test production are completed within approximately 3–6 months.
6. What factory space is required for installing a sandwich panel production line?
Factory space requirements depend on line length, panel size, and auxiliary equipment. A layout proposal can be provided based on available workshop dimensions.
7. Does the supplier provide on-site installation and technical support?
Yes. We dispatch 1–2 experienced engineers to the customer site to provide installation supervision, commissioning, and operator training, supporting the project from equipment installation through to stable production startup.
