If you need polycarbonate sheet production line, the options will usually fall into either single screw or double screw categories. Generally speaking, double screw polycarbonate sheet production line will be more efficient and faster to use, as the inclusion of two screws effectively doubles production capacity. But the cost of these plastic extruders is higher and if your production needs are more modest a single screw version will be fine. All styles can be found at wholesale prices by searching at Alibaba.com - the ideal place to equip a plastics processing plant.
