How to restore the deformation of laser cut acrylic board

Reasons for deformation of acrylic sheet during laser cutting
Acrylic sheet is a commonly used organic glass, which is widely used in industries such as advertising signs, lighting fixtures, furniture, etc. When laser cutting acrylic sheets, deformation may occur. There are various reasons for the deformation of acrylic sheets: it may be due to excessive laser power or temperature causing the acrylic sheet to soften, or it may be due to improper fixing methods causing uneven pressure inside the acrylic sheet, resulting in deformation.

Heating oven restoration
Acrylic sheets may deform after laser cutting and can be restored by heating an oven. The specific steps are as follows:
1. Place the acrylic sheet in the oven and adjust the oven temperature and time. The temperature should be controlled at around 60 degrees Celsius for about 10-15 minutes;
2. Observe the degree of deformation of the acrylic sheet, remove it from the oven, and immediately place it on a flat tabletop. Use a heavy object to press on the deformed area to restore the original shape of the acrylic sheet.

Re cut
If the method of heating the oven cannot restore the shape of the acrylic board, you can also consider re performing laser cutting. It is recommended to use a low-power laser for re cutting, and pay attention to adjusting the laser cutting parameters to achieve better cutting results. When re cutting, it is necessary to ensure stable operation, moderate cutting speed, and prevent deformation.

In summary, to address the issue of deformation in laser cut acrylic sheets, one can try using the recovery method of heating an oven or resort to re cutting to solve the problem. During operation, it is necessary to pay attention to adjusting the corresponding parameters and adopting a stable fixing method to avoid deformation.
