Precautions For Purchasing Extruder Barrel Screws

1. Inner diameter size of the barrel: The inner diameter size of the barrel determines the plastic processing capacity, so when selecting, it is necessary to choose the appropriate inner diameter of the barrel according to production needs.
2. Screw shape: Different shapes of screws can affect the mixing and melting of plastics, and need to be selected according to specific production processes.
3. Material of screw and barrel: When selecting, it is necessary to choose the appropriate material based on the properties and uses of the processed plastic, which is generally divided into two types: ordinary alloy steel and high-strength alloy steel.
4. Quality control: The manufacturing quality of the barrel and screw has a significant impact on the production efficiency, product quality, and lifespan of the extruder. In order to ensure production quality, it is necessary to choose a reputable manufacturer when purchasing.
In summary, as one of the core components of an extruder, the screw of the extruder barrel has a significant impact on the processing effect and production efficiency of plastics. When selecting, it is necessary to pay attention to the above key factors to ensure the production efficiency and product quality of the extruder.
