Aba Blown Film Machine

The extruder screw of the ABA film blowing machine is divided into three sections: the feeding section, the melting section, and the homogenizing section, as per the melting theory of plastics. It is important to note that the temperature at the end of the feeding section and the beginning of the melting section should be maintained at the viscous flow temperature. For different film blowing machines, the viscous flow temperature varies for different plastics. PP (polypropylene) typically ranges from 164-175℃, PE (polyethylene) ranges from 105-135℃, and PA (polyamide) ranges from 195-210℃. These temperature ranges are crucial for the efficient melting and homogenization of the plastics during the film blowing process.

In order to prevent the resin from blocking the feed inlet, it is preferred to have a lower temperature at the inlet of the feed section. Additionally, as the resin is continuously compressed in the feeding section, air is expelled backwards from the feeding port. The temperature of the charging port, although not electrically heated, typically ranges from 50-90 degrees due to heat transfer through the cylinder. This temperature determines the temperature of the feed section, with the entrance being 50-90 degrees and the end being equal to the melting point or viscous flow temperature. The temperature rise in this section can be described as a proportional linear increase.
The melting section of the PE blown film machine commences, raising the temperature until it reaches the viscous flow temperature for the resin to melt. For crystalline resins, the melting point temperature is equivalent to the viscous flow temperature. As the molten layer undergoes continuous compression, the temperature must continue to rise. This process causes the molecular chain length of the resin to change and various polymers with different thermal kinetic energies to melt successively. Once the temperature at the end of the melting section is determined, it can be inferred that the remaining sections should be heated linearly.
