Vented screw are two stage screw which works to remove volatilities of processing polymers during extrusion of different plastics. The position of vent in the barrel is very important, but the most important thing is to design both stages according to customer's need. Because output of Vented screw depends on both stages.

The vented screw is a specialized two-stage screw designed to efficiently remove volatiles during the extrusion of various plastics. Proper placement of the vent in the barrel is crucial for optimal performance. The key to maximizing output lies in customizing the design of both stages according to the specific needs of the customer. This design ensures improved material quality by eliminating unwanted gases and impurities during processing, making vented screws essential for high-quality polymer extrusion.
