1, first take a good measurement tool, scribe the line on the aluminium composite board, confirm the size, cut the aluminium composite board. Then according to the size of the need to bend in the back of the aluminum panel with the trimming machine # 6 trimming knife to repair the depth of about 1.5 mm line.
Align the trimming machine to repair the line, force to the location of the fracture mouth bend, do not repeatedly fold, so as not to fracture the aluminum panel.
2, the depth of the trimming knife repair needs to be appropriate, if the depth of the trimming knife is too deep will lead to aluminum composite panel easy to break and not round enough, but if the trimming knife is too shallow, it will lead to aluminum composite panel difficult to bend.
3, if you want to use the arc bending, we first need to tear the aluminium on the back of the aluminium composite panel with tools, tear the aluminium composite panel will be very easy to bend.
4, want to further processing, you need to use the fine mesh work or wood to do the skeleton, and then in a layer of 3 ~ 9 cm board to do the bottom, and then paste the words rounded corners will be very round and smooth.
After this has been introduced to you is not to understand some of it? If you still have what aspects of knowledge is needed to understand, you can pay more attention to us, should have a relatively good help effect on you!
