Aluminum composite panels (ACP) are flat metal panels that consist of two coil-coated aluminum sheets joined to each other by a non-metal polyethylene core. ACP is a popular choice for both internal and external architectural cladding due to its versatility, durability and flexibility. The non-metal core serves as an insulator and helps to reduce heat transfer between the two aluminum sheets. We offer PVDF, PE panels of glossy painted surface, brushed and mirror surface. ACP has a high strength to weight ratio and it has smooth clean lines that make it ideal for commercial construction.

Aluminum composite panels are produced with a detailed manufacturing process. Basically, the process involves coil coating of the aluminum skins then the lamination of the aluminum sheets, adhesive film, polyethylene core and the outer protective film. The coil coating process is a detailed multi-stage procedure that provides a uniform coating that has strong corrosion resistance and is aesthetically appealing.

After the sheets are uncoiled, they pass through a stitcher and entrance accumulators. Then they are de-greased before going through the anti-corrosion treatment. Next, the sheets are heated in an oven before a primer coat is applied. A primer oven helps to dry the first coat before the sheets move through air coolers.

Then the finish coating and drying is performed before the sheets are cooled and passed back to a re-coiler. The top exterior aluminum panel may be coated with different shades or grades of paint depending on the requirement of the customer. The panel thickness is usually between 1 to 8 mm.

To create the actual aluminum composite panels, the pre-coated aluminum sheets are passed through another manufacturing line that creates perfectly bonded aluminum sheets and a core. The process is based on a hot catalytic fusion mechanism. The adhesive film, made with special full blown technology, adheres to the LDPE core before the pre-coated aluminum top sheet and the second base sheet are bonded to it.

The process of bonding the metal to the adhesive film and core is known as lamination. It is used to combine two different substances (aluminum metal, adhesive film and polyethylene core) with the aid of molten polymers. The process combines the benefits of both lamination and extrusion to give a high quality bonded product. After all the substrates are uncoiled, they are passed through as series of heated rollers before they arrive at the cooling chamber.

When the panels have been inspected, a protective film is uncoiled and placed on the aluminum panels to protect it from scratches during packaging, loading and shipping. This film usually contains details about the composition of the panels and the protective coating. It needs to be removed immediately after installation.

After the film has been placed on the sheets, the composite panels will pass through the edge cutter where they are cut into the desired sizes. Subsequently, the panels are stacked with a hydraulic stacker and packed into specially protected containers for shipping.
