In the traditional production of sheet, film and other products, single screw extruders are usually used in the extrusion stage.
Since twin screw extruder has more superior plasticizing and dispersing capacity, it is more and more used in sheet extrusion equipment, panel extrusion equipment and casting film equipment.
On the one hand, it can improve the quality of products, and in many cases, it can also save the process of adding other ingredients to the granulate, greatly saving the production cost.
