Aluminum curtain wall has been widely used in indoor and outdoor walls, door signboards, window partition and other municipal infrastructure engineering decoration places, because the aluminum plate has better fire resistance performance, as well as flexible bending at any angle, engraving, punching, fillet roll arc and other material logistics performance. And bending (folding) is the most important aluminum veneerOne of the basic processes. Even if it is a common flat plate, it also needs a 20-25mm folding edge, which is convenient for installation and hanging hole (corner code) construction. Secondly, it also enhances the strength of the plate surface. The most commonly used is 90 degree right angle bending, of course, according to the design drawings for acute angle, right angle, obtuse angle and other customized bending angle. In order to adapt to a variety of modeling decoration places. Today we mainly talk about the commonly used 90 degree right angle, arbitrary angle, fillet, and bevel bending.
90 degree right angle bending:
As we all know, a right angle is a 90 ° angle. Is one of the most commonly used processes. Therefore, it is no longer necessary to elaborate. It mainly depends on the customer's requirements for plate joints, which are also right angles. Different equipment precision, process and plate joint are different.
If the customer does not have a special statement, the manufacturer uses the non slotted bending, the corner will have a little R angle effect, relatively speaking, this process will fold the edge of the plate seam will be slightly larger. If the customer has the requirement of close fitting, we will slot the edge before bending to minimize the R angle.
The fillet bending here is different from the R angle above. The corner of aluminum veneer on the wall is deliberately rounded to make the whole show a smooth decorative effect, which is no longer the traditional sharp edges and corners. It is also relatively safe.
Strictly speaking, this process is not a bending process, but a roll arc process. The fillet degree and arc length can also be customized according to the design drawings.
135 degree oblique bending:
135 ° oblique angle bending is to add a face on the basis of 90 degree right angle. No matter how much the face is increased, the default is 135 degree oblique angle on both sides. It can also be customized at any angle according to the engineering needs.
