The thickness of the acrylic sheet is related to the production process. Generally, the acrylic sheet is divided into two types: the extrusion process and the casting process. The plates produced by different processes have different physical and chemical properties. Generally speaking, the thickness is generally It is said that the thickness of the sheet of the extrusion process is between 0.8mm and 10mm, and less than 0.8mm is generally classified as acrylic sheet, which is larger than 10mm. Due to the limitation of the process, the extrusion sheet is difficult to perform. In short, the advantages of the extrusion process In the thin plate; the thickness of the acrylic sheet is relatively large in the casting process. Generally speaking, the lower limit is 1.5mm. Below this thickness, due to the limitations of its inherent thickness tolerance, there is some power failure. As for the upper limit of thickness, it is used from actual production. From the point of view, 50mm, 100mm is not a problem. Finally, the acrylic sheet thickness process produced by the extrusion process is generally within plus or minus 0.1 mm. It is not difficult to control it within plus or minus 0.05 mm, but the tolerance of the casting process is generally around 0.2 mm. As the thickness of the sheet increases, The tolerance value will also be larger.
