The single aluminum plate generally adopts Aluminum Alloy plate 1.5-4.0mm thick AA1100 pure aluminum or AA3003, exterior generally use 2.5mm and 3.0mm Aluminum Alloy thick plate; aluminum-plastic composite board generally uses 3 4mm three layer structure, including upper and lower two 0.5mm with PVC or PE; the aluminum honeycomb panel is selected 3003H24 aluminium alloy or 5052AH14 high quality manganese alloy aluminum base, panel thickness of 0.8~1.5mm fluorocarbon in acid rain corrosion and discoloration, self-cleaning property is better than PVDF, base plate thickness is 0.6~1.0mm, core material using hexagonal type 3003 aluminum honeycomb core, aluminum foil thickness 0.04~0.06mm, edge length 5~6mm. We can see from the material, aluminum-plastic composite panels must be much cheaper than the aluminum sheet. The processing of aluminum honeycomb panels is complex, and the molding products are more difficult than aluminum veneers.
The surface of aluminum single board is mainly treated by fluorocarbon spraying, aluminum veneer and imitation wood grain transfer, imitation marble and anodic oxidation, in which aluminum single board fluorocarbon spraying is the most widely used. Aluminum sheet processing is divided into two major steps: the first step is sheet metal processing. This process is mainly based on the aluminum plate after cutting, folding, bending, welding, assembly, polishing and other processes, the aluminum plate is processed into the shape and size of the construction of the. The second step is spraying. Surface painting is to spray paint on the machined sheet metal. Spraying is divided into two kinds, the machine is generally automatic spraying, and some shapes of aluminum single board need to be artificial spraying.
The processing process of aluminum plastic plate is more complicated than that of aluminum sheet. It is mainly composed of four major processes: forming, coating, compounding and trimming.
Aluminum honeycomb panel products are selected with a standard pre roll coating high-grade aluminum alloy coil, combined with a variety of production processes refined. The original coating technique is adopted to ensure the adhesion, color uniformity and saturation of the coating. The required color can be supplied according to requirements, and various special coatings can also be provided. Through the series mold gradually forming, fully release the stress inside the plate. The coating on the protective panel surface is not damaged and is more durable. The whole production process guarantees the high precision and continuous thermal compound production process of sheet metal processing with high efficiency and efficiency.
