The thickness of the paint layer is usually between 25 and 28 microns. The core material is made of low-density polyethylene (LDPE), which is compressed and bonded to the two aluminum sheets.

Bonding Technique

The bonding technique used in aluminum plastic panel manufacturing is a continuous lamination process. The aluminum sheets and the core material are passed through a set of rollers that apply heat and pressure to bond the layers together. The temperature and pressure are carefully controlled to ensure that the bonding is uniform and strong.

Cutting and Finishing

Once the bonding process is complete, the aluminum plastic panel is cut to the desired size and shape. The edges of the panel are then finished using a variety of techniques, including routing, sawing, and shearing. The finished panels can be further processed to add decorative or protective coatings.

Overall, the manufacturing process of aluminum plastic panel is a complex and precise process that requires careful attention to detail. By using high-quality materials and advanced bonding techniques, manufacturers can produce panels that are strong, durable, and aesthetically pleasing.
