How do bimetal screws and barrels improve plastic processing efficiency?

1. Optimize material handling
Increase plasticization and mixing levels:
The special design of the bimetal screw, such as changing the groove depth, thread shape, etc., can enhance the plasticizing and mixing effect of the material.
The optimized screw structure makes the residence time of the material in the extruder more reasonable, ensuring that the material is fully plasticized and mixed.
Expand the free volume of the screw channel:
In the feeding section and devolatilization section, the bimetal screw has a large free volume, which helps materials enter and pass through the extruder more smoothly.
Expanding the free volume of the feeding section and the filling degree of the material in the screw groove can greatly improve the processing capacity of the extruder.
2. Enhance equipment performance
Increase screw speed:
Bimetallic screws are able to withstand higher torque and rotational speeds, allowing the extruder to operate at higher speeds.
Increasing the screw speed can significantly shorten the residence time of materials in the extruder and improve production efficiency.
Optimize transmission system:
The matching use of bimetal screws and barrels puts forward higher requirements for the design and manufacturing level of the transmission box.
The optimized design of the transmission system, such as increasing the torque and selecting high-precision components, can ensure the stable operation of the extruder and reduce downtime.
3. Reduce energy consumption and wear
Reduce energy consumption:
The bimetal screw and barrel have good wear resistance, which can reduce friction and wear, thereby reducing energy consumption.
The optimized screw structure helps reduce the resistance of materials during the extrusion process and further reduces energy consumption.
Extend service life:
The bimetal screw and barrel have high corrosion resistance and wear resistance, can resist material erosion and wear, and extend service life.
Reducing the frequency of screw and barrel replacements reduces maintenance costs and the risk of production interruptions.
4. Improve product quality
Reduce defective rate:
The bimetallic screw and barrel can provide more stable extrusion conditions and reduce degradation and carbonization of materials during the extrusion process.
This helps reduce the defective rate and improve product qualification and consistency.
Improve product performance:
By optimizing the design of the screw and barrel, the mixing effect and plasticizing quality of the material can be improved.
This helps improve the physical properties, chemical properties and appearance quality of the product.
