How to hot bend plexiglass (acrylic)?

The weatherability and thermoplasticity of plexiglass are better than ordinary glass. People also know that both processing and hot bending are easier than ordinary glass, but many masters always have many unsatisfactory places when dealing with this process-yellowing, inaccurate size control, or blistering and so on. So what is the correct way to hot bend plexiglass?

I'm here to share my views with you.

The first point is to be comprehensive and accurate. Do you want to bend the acrylic or plexiglass? Whether it is imported or domestic must also be clear; How thick the sheets are also important.

Because these are the basis for correctly adjusting the baking and bending methods.

Second, adjusting the temperature of the oven is very important and particular. Many people think that heating plexiglass casually is enough to disprove it. Actually, it's not. Without the right medicine, scientific adjustment can not produce good products. What's the temperature of plexiglass? How thick is the board and how many degrees is it adjusted? How long does it take to bake? And so on are regular, combined with reality, not arbitrary. It is emphasized here that it is best to have a preheating process and take the step of heating in stages. Because if you keep the temperature too high for a long time from the beginning, acrylic can't bear it. Its inner surface has not been heated, but its outer surface has been blistered by high temperature.

The third point is the treatment and operation after hot bending and bending, which is very important. All preparations should be made before hot bending, and all necessary tools should be prepared. Observe whether the softness of plexiglass is appropriate and try to complete the bending at one time. In the process of bending, we must master the strength and the mold should be excellent. The last step is cooling, which depends on the quality requirements of your product. In short, a sharp cooling is not as good as a gradual cooling at constant temperature.

In this way, the bent product can keep bright without foaming. (Sincerity ~ Beauty ~ Opportunity ~ Glass ~ Glass ~ Mention ~ Dedication)
