aluminum composite metal Folding
After u-grooving, we can fold Aluloyal with a folding jig. The typical folding procedures are as follows:

Notes on folding aluminum composite metal :
Fold aluloyal aluminum composite metal panels on a flat and rigid worktable, because, if we fold a warping panel, the folding centerline will not be straight.
The folded corner should have suitable roundness of 2-3mm in radius. If the roundness is too small, the coating may have a crack on the folded corner. Check u-shape and grooving depth.
Cracks may occur when carry out the folding work at a low temperature. Have folding work at 10°C or higher.
Folding after u-grooving entails slight elongation. The elongation is 0.5-1.0mm per fold. Pre-adjust the position of the grooving line in your fabrication drawing.
