What factors affect the production capacity of the extruder?

What factors affect the production capacity of the extruder?


The factors affecting the production capacity of the extruder are as follows
The influence of screw geometry parameters on the production capacity of the extruder, here only the influence of the parameters that can be adjusted or changed in production are introduced

  1. Increasing the diameter of the screw can increase the production capacity of the extruder.
  2. The diameter gap between the screw and the feeder is too large, and the extruded material is affected by the resistance of the die, and the leakage flow will increase, and the production capacity of the extruder will decrease.
  3. The length of the homogenization section of the screw is increased, and the production capacity of the extruder can also be increased.
The influence of process conditions on the production capacity of the extruder
  1. Accelerate the speed of the screw, and the production capacity of the extruder will increase in proportion to the increase rate. The increase of low viscosity plastics is higher than that of high viscosity plastics, and the increase of high-melting temperature plastics is higher than that of low-melting temperature plastics.
  2. The resistance of the die of the machine head increases and the production capacity of the extruder decreases.
  3. The temperature of each section of the barrel affects the output of the product. In order to increase the conveying capacity, the temperature of the feeding section should be lower. Generally, this section should be cooled by water. The temperature of the melting section should be higher, and the temperature of the homogenization section should be slightly lower than that of the melting section, which is beneficial to the plasticization of materials. For temperature control, pay attention to fluctuations in the range of 3 degrees Celsius
The influence of plastic properties on the production capacity of extruders
  1. The influence of the size of plastic raw materials. When the plastic raw material particles are small, the production capacity of the extruder increases with the increase of the particle size, and when the particle size is large to a certain extent, the gap between the particles increases, and the production capacity of the extruder will increase with the increase of the particles. And reduce
  2. The influence of the melt flow rate, the greater the melt flow rate of the plastic, the easier it will flow, so the production capacity of the extruder increases with the increase of the melt flow rate.
  3. The influence of melting temperature. The higher the melting temperature, the longer the heat and time required for melting, so the production capacity of the extruder decreases as the melting temperature increases.
