3-5 Heating Zones Alloy Steel Screw Barrel for Extrusion for superior extrusion results and precise production process
Product Description:
Screw barrels are essential components of extruders, playing a crucial role in determining the melting, conveying, and extrusion efficiency of materials. Depending on whether they are designed with venting structures, they can be categorized into vented screw barrels and non-vented screw barrels. Both types are engineered to fulfill specific processing requirements, making them compatible with various materials and production scenarios.
Vented screw barrels are specifically crafted with one or more vent holes (typically 1-2) on the barrel, coupled with a corresponding vent section on the screw. This design aims at expelling volatile substances (like moisture, air, solvents, or gases) from materials during extrusion, 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. 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).
