Aluminum Composite Material (ACM) panels are typically manufactured through a continuous lamination process that combines multiple layers into a single, rigid panel.
The core process, as described in the provided reference, involves:
Manufacturing the composite panel system involves a continuous lamination process of compacting the core between two aluminum sheets, then flattening the product and applying a protective coating.
This method creates a lightweight yet strong panel widely used in construction and signage.
The Manufacturing Process for ACM Panels
The creation of ACM panels is a specialized industrial process involving several key steps performed continuously along a production line:
- Core Preparation: A core material, often polyethylene (PE) or a fire-retardant mineral-filled material, is extruded into a flat sheet.
- Aluminum Sheet Preparation: Two thin aluminum sheets are prepared. These sheets are typically cleaned and treated to ensure proper bonding. They may also receive a primer coating on the inner side.
- Lamination: The prepared core is fed between the two aluminum sheets. A continuous lamination process is used to bond the layers together under heat and pressure. This stage involves compacting the core between two aluminum sheets.
- Flattening: After lamination, the composite material passes through rollers to flatten the product, ensuring consistent thickness and surface smoothness.
- Protective Coating Application: The outer surfaces of the aluminum sheets receive a protective coating. This can include decorative color finishes (like PVDF or Polyester paints) and a peel-off protective film to prevent damage during transport and installation.
- Cutting and Finishing: The continuous panel is then cut to the desired lengths and widths. Edge finishing might also be applied depending on the product specifications.
This streamlined process ensures consistent quality and allows for the efficient production of large quantities of ACM panels. The resulting panel is a rigid, durable material with a smooth, flat surface suitable for various applications.
