2.0-3.0mm Alloy Depth Extruder Screw Barrel with HRC55-62 Quenching Hardness and 0.5-0.8mm Nitride Depth
Product Description:
Screw Barrels in Extruders
Screw barrels are crucial components in extrusion processes because they directly impact the melting, conveying, and extrusion efficiency of materials. These components are categorized into two types based on their design features: vented screw barrels and non-vented screw barrels. Each type is engineered to cater to specific processing requirements, making them suitable for various materials and production scenarios.
Vented Screw Barrels
Vented screw barrels are specially designed with one or more vent holes (typically 1-2) on the barrel, along with a corresponding vent section on the screw. This unique structure is specifically developed to eliminate volatile substances (such as moisture, air, solvents, or gases) from materials during extrusion. As a result, vented screw barrels ensure the purity and stability of the final product.
Non-Vented Screw Barrels
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. They are ideal 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).
