What is the working pressure of the melt pump in a sheet extruder?

The working pressure of the melt pump in a sheet extruder is a range value, with a normal working pressure generally between 5-20 MPa. However, melt pumps of different models and specifications may vary. Some melt pumps may have a relatively low inlet pressure, typically around 3-5 MPa, while the outlet pressure may be higher, sometimes reaching 40 MPa or even higher. However, the large pressure difference usually does not exceed a certain limit, such as 25 MPa.

In addition, it should be noted that the melt pressure in the extruder is also affected by various factors such as material characteristics, extruder models, and production processes. Therefore, in actual production, the working pressure of the melt pump should be set and adjusted according to specific production requirements and material characteristics to ensure the smooth progress of the production process and the stability of product quality.

At the same time, reasonably setting and maintaining the working pressure of the melt pump will also help improve the service life and production efficiency of the equipment. When using the melt pump, the pressure value should be set strictly according to the requirements to avoid excessive pressure that increases energy consumption and the risk of equipment damage, as well as too low pressure that affects production efficiency and quality stability.

The above information is for reference only. For more detailed and accurate data, it is recommended to consult the product manual of the melt pump in a sheet extruder or consult relevant manufacturers and technicians.
