Alloy Steel Extruder Screw Barrel with 2.0-3.0mm Alloy Depth
Product Description:
Screw barrels are crucial components of extruders, directly impacting the melting, conveying, and extrusion efficiency of materials. They are categorized into vented screw barrels and non-vented screw barrels based on whether they incorporate venting structures.
Vented screw barrels feature specialized design with one or more vent holes (typically 1-2) on the barrel, coordinated with a corresponding vent section on the screw. This configuration aims at eliminating volatile substances (such as moisture, air, solvents, or gases) from materials during the extrusion process to uphold the purity and stability of the final product.
On the other hand, non-vented screw barrels represent the standard type that lacks vent holes or vacuum structures. They 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)
