1. First, take the measuring tool and draw lines on the aluminum-plastic board. After confirming the size, cut the aluminum-plastic board. Then use the #6 trimming knife of the trimming machine to trim a line with a depth of about 1.5 mm on the back of the aluminum-plastic panel according to the required bending size. Aim at the line trimmed by the trimming machine, and bend forcefully toward the location of the fracture. Do not bend repeatedly to avoid breaking the aluminum-plastic panel.

2. The depth of the trimming knife needs to be appropriate. If the depth of the trimming knife is too deep, the aluminum-plastic panel will be easy to break and not round enough. But if the trimming knife If the repair is too shallow, it will make it difficult for the aluminum-plastic panel to bend.

3. If we want to use arc bending, we first need to tear off the aluminum on the back of the aluminum-plastic panel. The aluminum-plastic panel after tearing will be very It's easy to bend.

4. If you want further processing, you need to use fine workmanship or wooden squares to make the skeleton, and then lay a layer of 3~9cm board as the bottom, and then paste it into a round shape. The corners will be very rounded.

Application scope of aluminum-plastic rice:

1. Building exterior walls and curtain wall panels.

2. Modification and renovation of the old building exterior walls.

3. Balconies, equipment units, and indoor compartments.

4. Panels, sign boards, and display stands.

5. Interior wall decorative panels, ceilings, and advertising signs.

6. Industrial materials, body of cooling vehicle.

7. Housings for air conditioners, TVs and other home appliances.

Select arc length and angle dimensions.

The dimensions are controlled within 5 centimeters, and the building section is actually a vertical section of the entire house. Because the cutting position is determined according to needs, the specific cutting position of the building section must be expre ssed in the ground floor plan.

Stairs are passages that connect the upper and lower floors and are generally more complex, so sections are often expre ssed in stair sections. Similar to the floor plan, the exterior walls also have three dimensions, with the third being the third.

Extended information

In the projection drawing of the building form, in order to achieve complete dimension annotation, it can be analyzed according to the form Method, the size of the combination is divided into the following three categories:

1. Fixed size

The size required to determine the size of the basic geometry.

2. Positioning size

The size required to determine the relative position between basic geometries.

3. Overall size

The overall size refers to the total length, total width and total height of the combination.
