 Introduction to the Principle of Hollow Extrustion Blow Molding Machine

Simply put, a Blow Molding Machine is the process of blowing molten liquid plastic into different molds using the wind force to obtain various styles of blow molded products. Pe Extrustion Blow Molding Machine

The detailed principle process is that as the screw rotates, it is forced towards the direction of the machine head by the thread. Due to the resistance of the filter screen, splitter plate, and machine head mold at the machine head, and the gradual reduction of the capacity between the screw threads, the advancing material is subjected to great resistance. At the same time, it receives heat from the material barrel for heating. On the other hand, plastic is subjected to compression, shear, stirring and other forces during movement, which generates a large amount of heat from friction between the material barrel and the screw, The temperature of plastic in the machine barrel continues to rise, and after bending and plasticizing, the plasticized plastic is extruded from the machine head mold in equal pressure and quantity, which is called a plastic product with a certain shape. After cooling and shaping, the extrusion molding work is completed.Pet Stretch Blow Moulding Machine.
