High-strength Sandwich Panel Machine

Dec 13, 2025

The high-strength sandwich panel machine is a modern industrial equipment that integrates automation and intelligence, designed specifically for producing various types of sandwich panels for construction. The high-strength sandwich panel production line can combine two types of high-strength surface materials (such as steel plates, aluminum plates, or other composite materials) with intermediate core materials (polyurethane, rock wool, glass wool, etc.) through precision technology to form building panels with excellent insulation, sound insulation, and fire resistance properties.

High-strength Sandwich Panel Machine sandwich panel machine

High strength sandwich panel production lines usually have the following technical characteristics:

Fully automated control system, reducing manual intervention
High precision forming system ensures precise sheet size accuracy
Intelligent temperature control system, optimizing bonding effect
Modular design, easy to maintain and upgrade
Energy saving and environmentally friendly, in line with green manufacturing standards

Core components and functions of high-strength sandwich panel production machine

Open book and leveling system
As the starting point of the production line, the unwinding system is responsible for smoothly unfolding the rolled metal surface material. Modern equipment adopts hydraulic unwinding device and is equipped with automatic centering function to ensure precise positioning of materials when entering the production line. The leveling part is composed of multiple sets of rollers, which can eliminate the internal stress generated during the curling process of the material and ensure the flatness of the surface material.
Cleaning and pre-processing unit
This unit includes multiple processes: first, surface impurities are removed by brushing rollers, and then the metal surface is treated using chemical or physical methods to enhance the adhesion of subsequent coatings. High end equipment is also equipped with plasma treatment technology, which can further enhance the bonding strength.
Glue coating system
The core bonding process is completed by a high-precision glue coating machine. Modern equipment adopts two-component polyurethane adhesive automatic mixing spraying technology, which controls the adhesive amount through PLC to ensure uniform distribution of the adhesive layer. Some advanced models have achieved 3D scanning positioning spraying, significantly reducing the waste of adhesive materials.
Foam and Composite Unit
For polyurethane sandwich panels, a high-pressure foaming machine mixes the raw materials and injects them between two layers of material to complete the foaming and curing process in a strictly controlled temperature and pressure environment. Rock wool/glass wool sandwich panels adopt mechanical paving and hot pressing composite technology.
Forming and cutting system
The composite board enters the continuous forming unit and is shaped by multiple rolls to achieve the desired board shape (such as corrugated board, flat board, etc.). The CNC flying saw performs high-precision cutting according to the preset length, with an error controlled within ± 1mm. Some high-end equipment has introduced laser cutting technology.
Stacking and packaging unit
The automated stacking robot completes the stacking of sheets according to the preset program, and the intelligent counting system ensures accurate quantity of each stack. The packaging process can use automatic laminating or bundling devices for easy transportation and storage.
