Description

High Nitriding Hardness HV900-1000 and Quenching Hardness HRC55-62 Performance Screw Barrel with Vents

Product Description:

Screw barrels are the core components of extruders, directly determining the melting, conveying, and extrusion efficiency of materials. Based on whether they are designed with venting structures, they can be divided into vented screw barrels and non-vented screw barrels. Each type is engineered to meet specific processing needs, making them suitable for different materials and production scenarios.

Vented screw barrels are specially designed with one or more vent holes (usually 1-2) on the barrel, matched with a corresponding vent section on the screw. This structure is dedicated to removing volatile substances (such as moisture, air, solvents, or gases) from materials during extrusion, ensuring the purity and stability of the final product.

Non-vented screw barrels are the standard type without vent holes or vacuum structures. They focus on efficient material conveying, melting, and extrusion, suitable for materials with low gas content or stable performance 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)
