Product Description:

Screw barrels are crucial components of extruders, playing a direct role in determining the melting, conveying, and extrusion efficiency of materials. They can be categorized into vented screw barrels and non-vented screw barrels based on whether they are designed with venting structures. Each type is specifically engineered to cater to distinct processing requirements, making them suitable for various materials and production scenarios.

Vented screw barrels are engineered with one or more vent holes (typically 1-2) on the barrel, in conjunction with a corresponding vent section on the screw. This design is aimed at expelling volatile substances (e.g., moisture, air, solvents, or gases) from materials during extrusion, ensuring the purity and stability of the end product.

Non-vented screw barrels represent the standard type without vent holes or vacuum mechanisms. They prioritize efficient material conveying, melting, and extrusion, making them ideal 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).
