The automatic blowing machine factory tells you the principle of the product

The automatic blowing machine factory will introduce to you: After the hopper enters the barrel of the extruder, with the rotation of the screw, it is forced to push towards the head of the machine by the thread. Due to the resistance of the filter screen at the machine head, the splitter plate, and the die of the machine head, and the capacity between the screw threads is gradually reduced, the advancing material is subjected to great resistance, and at the same time is heated by the heat introduced by the barrel; on the other hand , When the plastic is subjected to compression, shearing, stirring and other forces during movement, the friction with the barrel, the screw and the friction between the plastic molecules will generate a lot of heat.

The automatic blowing machine factory tells you: As the temperature of the plastic in the barrel continues to rise, its physical state gradually changes from a glass state to a high elastic state, and finally becomes a viscous flow state, and is further completely plasticized. As the screw is constantly rotating, the plasticized plastic is extruded from the die of the machine head under equal pressure and equal amount, which is called a plastic product with a certain shape. After cooling and shaping, the extrusion molding work is completed.
