    Aluminium Composite Panel: The Process of Manufacturing

    By : viva   |  Category : Aluminium Composite Panel  |  0 Comment

    Aluminium composite panels may be made in a variety of ways. Cold composite technique and heat composite method are two types of composite methods for plastic core panels and two-sided aluminium panels, respectively. However, we will discuss how VIVA manufacture their ACP sheets while maintaining the quality standard.

    Cleaning the aluminium coil is the first step in the fabrication of aluminium composite sheet. VIVA procure the aluminium coil from Hindalco. As the process of production of demands, the surface of aluminium coils is covered with lubricants and anti-oxidants, and some dirt will adhere during transit, affecting adhesion and necessitating cleaning. We degrease, de-oxidize, and chromatize the coil while passing it through a series of tanks.

    Degreasing is a technique for removing oil and other impurities from a surface. To remove the water from the coil, deoxidizing is done, and chromatization is used to create the abrasive surface. For good primer adhesion on aluminium surfaces, an abrasive surface is essential.

    A dense chemical protective layer forms on the surface of the aluminium coil after cleaning and chemical treatment; this chemical film can increase the aluminium coil’s oxidation resistance and extend the life of the paint film. The grains are then melted into sheet shape to create the core. On both sides of the Core, the adhesive (Adhesive sheet is purchased from DuPont) film is applied.

    We at VIVA fed the cleaned aluminium coil to a coater and coat the outside surface of the aluminium coil with a high-performance fluorocarbon resin. Two coats of paint and primer are applied to the panels of the aluminium composite sheet. We use paints that are procured from renowned manufacturers like Nippon, Spectrum, PPG, Monopol, Akzonobel and the customization of shades been manufactured In-house. The topcoat is a fluorocarbon resin coating called polyvinylidene fluoride(PVDF), which is highly weather resistant. Its strong UV resistance and resistance to contamination keep the coated aluminium coil’s surface looking attractive. Fluorocarbon coatings are typically applied to aluminium coils using a roll coating process and then dried at high temperatures. There are three layers of paint and to dry each paint coat it must be baked at 240 °C for around 45 seconds.

    To make a sandwich panel, coils are put on top and bottom of the core. Laminate aluminium coil to the core using induction roller heating. Our ACP has been brought to normal temperature using a cooling tower, and it is now ready to use. The protective film can now be applied to the ACP sheet. The self-adhesive protection film can be removed after installation. To avoid damaging the surface coating during future processing, transportation, and installation, a protective layer is added to the coating’s surface. The protective film also comes with the direction of the installation of ACP sheets while ACP cladding.

    Finally, the ACP board and ACP sheets are cut into the customized length. However, Pallet Packaging is also used by VIVA to preserve sheets during shipping. Loading the sheets into trucks while making sure the ACP reaches the retailer, architects, and facade consultants. Throughout the transportation process, we maintain a consistent communication process.

    Voila! Now, it’s time to install the ACP sheets to beautify your façade with VIVA ACP sheets.
