How do bimetallic screws and barrels reduce energy consumption during plastic processing?

1. Optimize design to reduce friction
The bimetallic screw and barrel are made of wear-resistant and corrosion-resistant materials with high hardness and finish, which reduces friction resistance during plastic processing. This design helps reduce energy consumption, as friction is an important component of energy consumption in plastic processing. By reducing friction, the extruder can run more smoothly and energy consumption is reduced.

2. Improve plasticization efficiency
The unique design of the bimetallic screw can plasticize and mix plastics more effectively. This includes changing the depth of the screw groove, the shape of the thread, etc. to optimize the flow and mixing of the material in the screw. Efficient plasticization efficiency means that the plastic can be more fully heated and mixed in the screw to achieve the required processing temperature, reducing heating time and energy consumption.

3. Optimize screw speed
The bimetallic screw can withstand higher torque and speed, which allows the extruder to run at higher speeds. In the plastic processing process, increasing the screw speed can shorten the residence time of the material and improve production efficiency. At the same time, due to the increase in speed, the amount of plastic processed per unit time also increases accordingly, thereby allocating energy consumption and reducing overall energy consumption.

4. Improve equipment stability
The wear resistance and corrosion resistance of the bimetallic screw and barrel enable the equipment to maintain high stability during long-term operation. Stable equipment operation reduces downtime and maintenance costs, and also avoids increased energy consumption due to equipment failure. In addition, stable equipment operation also helps to improve product quality and production efficiency, thereby indirectly reducing energy consumption.

5. Reasonable cooling system
In the plastic processing process, a reasonable cooling system is crucial to reducing energy consumption. The design of the bimetallic screw and barrel usually takes into account the layout and effect of the cooling system. Through effective cooling, the temperature of the screw and barrel can be reduced, reducing energy consumption. At the same time, a reasonable cooling system also helps to maintain the stability of the equipment and extend its service life.
