Hyperbolic aluminum veneer is a classification of aluminum veneer. Hyperbola is the overlap of two different arcs on the same surface, that is, starting from different centers, the arc is drawn with two radii, because the common wave shape is a single-curved aluminum veneer. The processing steps of hyperbolic aluminum veneer are mainly divided into two parts:

The first is sheet metal processing. Sheet metal processing is mainly used to process the appearance and size of the hyperbolic aluminum veneer. The "general direction" of the aluminum veneer. The process is the cutting, folding, bending, welding, polishing and other processes required to cut the aluminum veneer into a structure. Shape and size, this part of the process determines important parameters such as the curvature and appearance of the aluminum veneer. The second is spraying. Spraying is to spray the finished aluminum plate. There are two kinds of spraying, one is manual spraying and the other is mechanical spraying. Mechanical spraying is generally only suitable for ordinary plates, but this type of aluminum veneer is rarely used in practical applications, and most domestic manufacturers use manual spraying. One of the advantages of hand spraying is that you can choose the color regardless of size. The hyperboloid aluminum veneer needs to be pre-sprayed before spraying to obtain the best results.
