What impact does the thermal conductivity of Bimetallic Screw And Barrel have on plastic processing?

The thermal conductivity performance of Bimetallic Screw And Barrel has a significant impact on plastic processing, which is mainly reflected in the following aspects:

1. Heating efficiency and energy consumption
The heat conduction properties of the bimetal screw and barrel determine their efficiency during the heating process. Higher thermal conductivity means that heat can be transferred into the plastic melt faster, thereby increasing heating efficiency. This helps shorten the production cycle and improve production efficiency. At the same time, due to the improvement in heating efficiency, the required energy consumption will be reduced accordingly, thereby reducing production costs.

2. Temperature uniformity
During plastic processing, maintaining temperature uniformity in the screw and barrel is critical. Due to their good heat conduction properties, the bimetallic screw and barrel can respond more quickly to the adjustments of the temperature control system, thereby ensuring that the temperatures of the screw and barrel remain consistent. This helps reduce the temperature difference of the plastic melt during the extrusion process, improving product quality and consistency.

3. Fluidity of plastic melt
The fluidity of plastic melt is significantly affected by temperature. The thermal conductivity of the bimetallic screw and barrel ensures that the plastic melt maintains a suitable temperature range during the extrusion process, thereby improving its fluidity. Good fluidity helps reduce resistance during extrusion and improve extrusion speed and quality.

4. Avoid overheating and degradation
During plastic processing, excessively high temperatures may cause the plastic melt to degrade, thus affecting the quality and performance of the product. Due to their good thermal conductivity, the bimetal screw and barrel can transfer heat to the plastic melt more effectively while avoiding local overheating. This helps reduce the risk of plastic melt degradation and improves product quality and stability.

5. Extend the service life of equipment
The heat conduction performance of bimetal screws and barrels is also closely related to their service life. Because heat is transferred into the plastic melt more quickly, the screw and barrel are heated less, reducing material fatigue and wear caused by high temperatures. This helps extend the life of the equipment and reduces repair and replacement costs.
