Quenching Hardness HRC55-62 Screw Barrel For Extruder Granulation Machine

Product Description:

Screw barrels are essential components of extruders, playing a critical role in controlling the melting, conveying, and extrusion efficiency of materials. Depending on the presence of venting structures, screw barrels can be categorized into vented and non-vented types. Each type is engineered to meet specific processing needs, making them suitable for different materials and production scenarios.

Vented screw barrels are specifically designed with one or more vent holes (typically 1-2) on the barrel and a corresponding vent section on the screw. This unique engineering allows for the removal of volatile substances (such as moisture, air, solvents, or gases) from materials during extrusion, ensuring the purity and stability of the final product.

On the other hand, non-vented screw barrels are the standard type that lacks vent holes or vacuum structures. These barrels prioritize efficient material conveying, melting, and extrusion processes, making them ideal for materials with low gas content or stable properties that do not require 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).
