Experimental Film Blowing Machine Working Principle

Experimental film blowing machine is to add raw material particles (LDPE, HDPE, LLDPE, filler, etc.) into the hopper, from the hopper into the screw, when the raw material and the threaded oblique edge contact, the rotating oblique edge will push the raw material particles forward, in the process of pushing, through the extrusion friction heat and external heating and gradually dissolve, the molten raw material is extruded from the die mouth. Through blowing expansion, wind ring cooling, traction frame pull up, traction roll, and then through the winding frame to wind up into film cylinder material.
