Slotting, also known as gouging, is one of the commonly used technological processes in sheet metal processing. The V-shaped cutter is used to dig out a groove at the bending corner of sheet metal parts by slotting machine, so that the bending radius is smaller and the sheet metal parts reach the true 90 ° right angle. Increase the beauty of materials.

Whether the ceiling of aluminum veneer curtain wall should be slotted and bent depends on whether the installation nodes are closely assembled, and the close assembling is also divided into conventional close splicing and pure close splicing. If the aluminum veneer is not slotted and bent, even if it is closely assembled, there will be two R rounded corners at the seam position of the folded edge, so the slotting technology emerges as the times require.

The thickness of slotted aluminum veneer is generally more than 2.5mm to ensure safety. It is suggested that the material thickness should be 3.0 mm, because the grooving will excavate about 0.5 mm V-shaped groove at the bending position. Therefore, in order to ensure the material safety performance to meet the wind pressure and seismic resistance coefficient, the macro aluminum veneer manufacturer recommends using 2.5 ~ 3.0 mm material for processing.

Generally, bending coefficient should be calculated according to the thickness of aluminum sheet when bending, but bending coefficient and K-factor equation are no longer applicable to the plate after grooving.

Slotted bending close assembly installation, almost no seam.

Generally speaking, slotted aluminum veneer is often used in indoor seamless installation places, or the plate surface is provided with precise patterns, and the patterns are scattered on multiple boards. Therefore, the close assembly installation process of slotting and bending is needed to reduce the pattern gap and perfectly reflect the meaning of graphics and text. If it is not patterned aluminum veneer, outdoor installation of conventional close fitting is enough to meet the requirements.

Aluminum veneer slotting is not only limited to 90 degree right angle bending, but also can be customized according to the required angle. By adjusting the parameters of the slotting machine, various requirements can be met.

Some customers require slotting on the board surface as decorative lines, and can also be customized according to the drawings.
