Product Description:

Screw barrels play a pivotal role in extruders as they directly impact the melting, conveying, and extrusion efficiency of materials. These components can be categorized into vented screw barrels and non-vented screw barrels based on whether they incorporate venting structures. Both types are meticulously engineered to meet specific processing requirements, enabling them to cater to various materials and production scenarios.

Vented screw barrels are specially designed with one or more vent holes (typically 1-2) on the barrel, along with a corresponding vent section on the screw. This configuration is tailored to expel volatile substances (such as moisture, air, solvents, or gases) from materials during the extrusion process, thereby ensuring the purity and stability of the end product.

On the other hand, non-vented screw barrels represent the standard variety devoid of vent holes or vacuum structures. These barrels prioritize efficient material conveying, melting, and extrusion, making them suitable for materials with low gas content or stable performance that do not necessitate degassing.

Applications:

Ideal for materials that are prone to trapping gases or containing volatile components, such as:

• Recycled plastics (which may absorb moisture or contain residual solvents).
• Hygroscopic materials like PA (polyamide) and PC (polycarbonate).
• Materials requiring high purity, such as medical-grade plastics or food packaging materials.

Perfect for dry, low-volatile, or high-stability materials, including:

• Common non-hygroscopic plastics like PP (polypropylene) and PE (polyethylene).
• Pre-dried materials that have been fully dehumidified.
• Materials for simple extrusion processes such as film blowing, pipe extrusion, or profile extrusion (where minor gas content has little impact on product performance).
