We prefer to open a groove from the back of the aluminum-plastic composite panel with a slotting machine (trimming machine), otherwise it will not fold. The depth of the groove is adjusted according to the thickness of the aluminum plastic. First, shorten the cutter head and try it slowly until it seems that the aluminum peel does not seem to be exposed. Deep and easy to scratch the aluminum skin to cause the hem to break, shallow and not easy to fold, easy to burst.
In addition, the cutter head is used, and there are two kinds of cutter heads, U-shaped (popularly called round to head) and V-shaped (popularly called sharp cutter head). The U-shaped cutter head is not easy to scratch the aluminum skin, but the folded corner is not Very straight, V-shaped cutter head is more straight than the angle of the pointed corner, the angle is better, but it is easy to scratch the aluminum skin and cause the aluminum skin to crack. Generally, the 4 mm aluminum-plastic plate can be used with the 6# cutter head.
