PP/PE/PET Extrusion Machine Extruder Screw Barrel with Base Material 38CrMoAlA and Quenching Hardness HRC55-62
Screw barrels are the core components of extruders, directly determining the melting, conveying, and extrusion efficiency of materials. Based on whether they are designed with venting structures, they can be divided into vented screw barrels and non-vented screw barrels.
Each type is engineered to meet specific processing needs, making them suitable for different materials and production scenarios.
Vented screw barrels are specially designed with one or more vent holes (usually 1-2) on the barrel, matched with a corresponding vent section on the screw. This structure is dedicated to removing volatile substances (such as moisture, air, solvents, or gases) from materials during extrusion, ensuring the purity and stability of the final product.
Non-vented screw barrels are the standard type without vent holes or vacuum structures. They focus on efficient material conveying, melting, and extrusion, suitable for materials with low gas content or stable performance that do not require degassing.
Ideal for materials that are prone to trapping gases or containing volatile components, such as:
Perfect for dry, low-volatile, or high-stability materials, including:
