What are the functions of the components of the film blowing machine?
1 The extruder is responsible for melting, plasticizing, and extruding the resin, which mainly affects the plasticization of the film.
2 Inside the machine head is a spiral body, responsible for the cross-mixing of plastics, which has an impact on the tensile force and strength of the film.
3 The die head controls the expansion ratio of the film, which has an impact on the strength and stability of the film, generally 1:3.5
4 The cooling device is responsible for cooling the film bubble, which has a great influence on the film strength, as well as the stability and brightness.
The other parts do not have much influence on the membrane, as long as the membrane is flat and the strength meets the requirements.
