Choosing the Right Bimetallic Screw Barrel for Your PVC Applications

When sourcing a bimetallic screw barrel for high-filled PVC, several key factors must be considered to achieve your production objectives.

Why Custom Screw Barrels Matter for Bio-Based Plastics

Bio-based plastics, derived from renewable resources, have unique processing characteristics. Custom screw barrels tailored for these applications can improve material flow, enhance melt quality, and ensure higher output efficiency. When processing polymers like PLA or PHA, which have different thermal and viscosity properties compared to traditional plastics, a standard screw barrel may not suffice. A custom solution can mitigate issues like poor mixing, degradation, and output inconsistencies.

Key Material Considerations for Custom Screw Barrels

Material selection is crucial for screw barrels used with bio-based plastics. Options such as wear-resistant bimetallic alloys can significantly enhance the lifespan of the screw barrel when processing filled bio-plastics. For instance, incorporating a bimetallic design allows for improved resistance against wear and corrosion while ensuring optimal performance. Additionally, the diameter and geometry of the screw can be adapted specifically for the processing behavior of the chosen bio-plastic, such as using a 30% GF (Glass Fiber) fill level for enhanced strength.
