Because the super surface (four points coplanar) building epidermis has nonlinear changes in the vertical and horizontal directions, even in the interlayer of the same height, the horizontal angle and length of the adjacent building epidermis are different, so the building epidermis cell plates are almost standard size plates, greatly increasing the complexity of processing, long construction period and high production cost. Free surface aluminum, also known as hyperboloid aluminum veneer in the construction industry. Well, thisHyperbolic aluminum veneerHow did you get out? I believe you will be interested!

Thermoforming: roll the aluminum plate into a roughly hyperbolic shape, then heat it, then put it on a pre fabricated mold, slowly hammer it into shape, and then cut, weld, polish and polish it. The whole process must be very careful to ensure the surface quality of hyperbolic aluminum veneer. This forming method is very suitable for parts with small model and large arc variation. When the size of the model is large and complex, it can be considered to be divided into small pieces and then spliced into large blocks. For this hyperbolic aluminum veneer, the cost is high, the time limit is long, and the surface is difficult to guarantee. Therefore, the processing difficulty of hyperbolic aluminum veneer in the grid must be considered.

Rolling forming method: this method is modified on the rolling machine. Change one axis to a female axis and the other to a male axis. This method can be used to form hyperbolic aluminum veneer which is similar to spherical surface and has regular processing range. However, for some hyperbolic aluminum veneers with small radian, it has great advantages.

Stamping forming method: this method can form almost all hyperbolic aluminum veneers, but almost no hyperbolic aluminum veneers are formed. Since the cost of the forming method is so high that you can't believe it, you can imagine the processing cost and material cost of the iron mold.

Cold drawing forming method: I recommend this method. I think this is reasonable and worth promoting. The price of hyperboloid aluminum veneer is about 450-800 yuan per square meter.

The above is about the price of hyperbolic aluminum veneer.
