What is the impact of the wear of the Screw Barrel For Extrusion Machine on product quality?

The impact of the wear of the Screw Barrel For Extrusion Machine (extruder screw) on product quality is mainly reflected in the following aspects:
Degradation of product quality:
The wear of the screw will increase the gap between it and the barrel, making the pressure and temperature of the plastic during the extrusion process unevenly distributed, thereby affecting the dimensional accuracy and surface quality of the product.
A severely worn screw may also cause the plastic to fail to be fully mixed and plasticized during the extrusion process, resulting in defects such as bubbles and impurities inside the product, which seriously affects the quality of the product.
Reduced production efficiency:
After the screw is worn, the production capacity of the extruder will decrease because it takes longer to reach the required extrusion pressure and temperature.
Wear may also cause the screw speed to decrease, further reducing production efficiency.
Increased energy consumption:
After the screw is worn, in order to maintain normal extrusion pressure and temperature, energy consumption needs to be increased to provide additional power.
This not only increases production costs, but may also have a negative impact on the environment.
Increased safety hazards:
When the screw is severely worn, it may cause safety accidents such as screw breakage or barrel rupture, which seriously threaten the life safety of the operator.
In summary, the wear of the Screw Barrel For Extrusion Machine will seriously affect the quality, production efficiency, energy consumption and safety of the product. Therefore, during use, it is necessary to regularly inspect and maintain the screw, and replace the severely worn screw in time to ensure the normal operation of the extruder and the stability of product quality. At the same time, when purchasing a screw, you should choose a product with reliable quality and good wear resistance to reduce the impact of wear on product quality.
