Sheet extruders
The plastic pellets enter the barrel through a hopper at one end of the barrel. They are then transferred via the screw to the other end of the barrel. In order to have sufficient pressure. The depth of the threads on the screw decreases as the distance from the hopper increases. Due to friction between the plastic and the screw, external heating and internal heating. Softening and melting of the plastic. In general, different polymers are used for different applications. Plastic extruders are designed with special mixing devices to discharge the outlet, multiple feed ports and along the screw. Melt cooling and heating. External heat source. Relative variation in clearance between the screw and the barrel. and the number of screws. Finally, the desired thickness and width of material is extruded.
