Aluminum plastic panel manufacturing process

Update:28 Apr 2024

Material preparation: Prepare the required aluminum plates and plastic core materials. Aluminum plates can be pure aluminum or aluminum alloys. Commonly used alloys include AA1100, AA3003 and AA5052. Plastic core materials are usually polyethylene (PE) or polyurethane (PU).
Surface treatment: Clean and pre-treat the aluminum plate to ensure that the surface is clean and provides good adhesion for subsequent coating and bonding. This step can include treatments such as decontamination, degreasing, pickling and anodizing.
Plastic core coating: The plastic core material is coated between two aluminum plates to form a pre-pressed plate. Coating can be carried out using a coating machine or coating roller to ensure that the plastic core material is evenly covered on the surface of the aluminum plate.
Hot press lamination: The pre-pressed plate is put through a hot press lamination process to firmly bond the aluminum plate and plastic core material together. This step is usually carried out under high temperature and pressure to ensure the firmness and bonding strength of the composite layer.
Cooling and leveling: The composite aluminum-plastic panel is cooled through the cooling system to reduce its temperature and solidify. Then, the board is leveled by a leveling machine to ensure the flatness and dimensional accuracy of the board.
Cutting and processing: Cut the flattened aluminum-plastic panels according to the required size. Cutting can be done using a saw, CNC cutter or shearing machine. Depending on the specific application requirements, further processing such as bending, perforation, etc. may be required.
Surface treatment and painting: Surface treatment and painting of aluminum-plastic panels as required. Surface treatment can include anodizing, sandblasting, electrophoretic coating, etc. to enhance the corrosion resistance and decorative effect of the surface. Coating can be done using a coating machine or a spraying process to give the aluminum-plastic panel the desired color and texture.
Inspection and packaging: Conduct quality inspection on the manufactured aluminum-plastic panels to ensure that they comply with relevant standards and regulations. The aluminum-plastic panels are then packaged to protect their surfaces from damage and facilitate storage and transportation.
The above steps are the basic flow of the general aluminum-plastic panel manufacturing process. The specific manufacturing process may vary due to different production processes and manufacturers. In actual production, it is also necessary to strictly control the process parameters and quality requirements of each link to ensure the production of aluminum-plastic panel products that meet specifications and quality requirements.
