Casting Acrylic Sheets, extrusion acrylic sheets -- production process and advantages & disadvantages
Casting acrylic sheet, just as the name implies is to melt acrylic raw materials at high temperature, placed in the mold casting production. Due to the high quality of the molecules produced, they have excellent stiffness, transparency, and excellent chemical resistance. Acrylic casting sheet has very good transparency, and the specifications of the product is very complete, small batches of time can also be very convenient to buy the plate, but also has incomparable flexibility in color and surface texture. Therefore, it is now the most widely used plate sheet.
Disadvantages: because it is pouring molding, so the plate in the thick above the error is larger, and because the size of the whole plate is fixed, in the production of some larger products, easy to cause the waste of plate scraps, improve the unit price of the product. Because the plate is cast molding, so the production process needs a lot of cooling water, easy to produce sewage, pollution to the environment.
If talking about extrusion acrylic sheet, then the first to start from the production process of acrylic extrusion sheet. Acrylic extrusion sheet is generally the first step to melt acrylic raw materials, and then through high temperature extrusion of mechanical equipment. Due to the impurities produced in the melting of acrylic raw materials, the pitting problem has been in the extrusion process. The acrylic extrusion sheet is also divided into first-class and second-class products in quality. Although acrylic exrusion sheet is not as transparent as acrylic casting sheet, it also has its own advantages, for example, The thickness tolerance is very small, the color can be customized, so it is suitable for making into mirror acrylic sheet after plating.
