Core Materials
Aluminum composite material (ACM) panels have a three-layered structure consisting of two aluminum sheets bonded to a thermoplastic core material. The core material is typically made of low-density polyethylene (LDPE) or fire-retardant (FR) mineral-filled core. LDPE core is lightweight and flexible, while FR core has better fire resistance properties. The thickness of the core material varies depending on the application and performance requirements.
Surface Coatings
The surface coatings of ACM panels are critical to their performance and aesthetics. The coatings are typically made of either polyvinylidene fluoride (PVDF) or polyester (PE) resin. PVDF coatings are more durable and resistant to weathering, fading, and staining, making them suitable for exterior applications. PE coatings are less expensive but have lower durability and are more prone to fading and staining.
ACM panels come in a variety of colors, finishes, and textures, allowing architects and designers to create visually appealing facades and interiors. The panels can be easily fabricated and installed, making them a popular choice for cladding, signage, and interior decoration applications.
Overall, ACM panels offer a lightweight, durable, and versatile solution for architectural and construction projects. However, it is important to ensure that the panels meet the relevant safety and performance standards and codes to ensure their safe and effective use.
Manufacturing Process

Material Preparation
The first step in the manufacturing process of aluminum composite material panel (ACM) involves preparing the materials. The aluminum sheets are cleaned and treated with a chromate solution to improve adhesion. The core material, which is usually made of polyethylene, is also cleaned and treated with a flame retardant.
Bonding Techniques
Once the materials are prepared, the bonding process begins. There are two main bonding techniques used in the manufacturing of ACM panels: continuous and discontinuous bonding.
In continuous bonding, the core material is continuously fed between two aluminum sheets, which are then bonded together using a high-pressure roller. This results in a continuous panel with a uniform thickness.
In discontinuous bonding, the core material is glued to the aluminum sheets in a patterned or random manner. This results in a panel with varying thicknesses and a more irregular appearance.
Cutting and Shaping
After the bonding process is complete, the panels are cut and shaped to the required size and shape. This can be done using a variety of techniques, including sawing, routing, and punching.
ACM panels can be cut and shaped into a wide range of shapes and sizes, making them a versatile material for a variety of applications. The panels can also be coated with a variety of finishes, including paint, powder coating, and anodizing, to further enhance their appearance and durability.
Types and Varieties

Other mechanical fastening methods include rivets and clips. Mechanical fastening is a quick and easy installation method that allows for easy removal and replacement of panels if necessary.
Adhesive Bonding
Adhesive bonding is another installation method for aluminum composite material panels. This method involves applying an adhesive to the back of the panel and then pressing it onto the substrate. Adhesive bonding provides a strong, permanent bond and is ideal for applications where mechanical fastening is not practical or desired. However, it can be a more time-consuming installation method and requires careful surface preparation to ensure proper adhesion.
Panel Joining Methods
When installing aluminum composite material panels, it is often necessary to join two or more panels together. Panel joining methods include tongue and groove, shiplap, and butt joint. Tongue and groove and shiplap joints provide a more secure and weather-resistant joint, while butt joints are simpler and easier to install.
