1. First obtain the required aluminum-plastic plate and corresponding tools, and measure the required bending radius with a measuring tool (such as a steel ruler or protractor) according to the required circle diameter.

2. Secondly, put the marked aluminum-plastic plate on a heating table, and heat the plate locally with a hot gun or heater.

3. Finally, in the process of bending on the heating area, wooden templates or other curved surfaces can be used to help shape the expected circle. After bending, the aluminum-plastic plate is naturally cooled to solidify its shape, so as to avoid striking or bending the cooled aluminum-plastic plate hard to avoid cracking or deformation.
