How are polycarbonate sheets of various shapes and colors made?
In daily life, we can see polycarbonate sheets everywhere. Many of these sheets come in different shapes and a wide range of colors. So how are these shapes actually created? In fact, these shapes are achieved through the processing of polycarbonate sheets. As for the different colors, how are they achieved? When polycarbonate sheets are produced and sold, there are many color options available, such as lake blue, grass green, transparent, milky white, smoke gray, etc. The coloring process for polycarbonate sheets is relatively simple and is generally achieved by adding colorants.

There are two methods to change the shape. One involves using the cooling water ring method to set the shape of the polycarbonate sheet. This requires manual control of the water flow rate so that different parts of the sheet surface experience varying forces, thereby achieving the desired effect. Another method is the cold air circulation method, but this approach is significantly more challenging to control manually. If an inexperienced operator performs the processing, it can lead to surface defects in the polycarbonate sheet. Therefore, the cooling water ring method is generally used in the market for secondary processing of polycarbonate sheets.
