Industrial Grade Extruder Screw Barrel With Bimetallic Treatment HRC58-62 Hardness 3-5 Heating Zones

Product Description:

Screw barrels are crucial components of extruders, playing a key role in the melting, conveying, and extrusion efficiency of materials. Depending on the presence of venting structures, they are categorized into vented screw barrels and non-vented screw barrels. Each type is designed to cater to specific processing requirements, making them suitable for various materials and production scenarios.

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

Non-vented screw barrels, on the other hand, are the standard type that lacks vent holes or vacuum structures. They are focused on efficient material conveying, melting, and extrusion, making them suitable for materials with low gas content or stable properties that do not require degassing.

Applications:

Designed to cater to a specific set of material requirements, our material drying equipment is most suitable for substances that are prone to trapping gases or contain volatile components. This includes:

• 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.

On the other hand, our equipment is also highly effective for dry, low-volatile, or high-stability materials, which include:

• 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.
