1. Three main working factors of film blowing machine

1) It has a great relationship with the temperature of the equipment when producing film products. The temperature control of the film blowing machine includes the temperature of the starting machine itself and the temperature of the starting environment. The temperature should be controlled within a certain reasonable range, so as to ensure the rational operation of the machine.

2) Spirochete structure, process detail. Spiral body is the key to the performance of film blowing machine and one of the important components.

3) Cooling system of film blowing machine. The function of the cooling system is to make the film achieve a certain cooling effect.

2. Advantages of adopting internal cooling control system for three-layer coextrusion film blowing machine

1) With the rapid development of plastic industry and the emergence of various new raw materials, people have increasingly strict requirements for plastic products. The traditional fan and air ring have been difficult to meet the requirements, resulting in the disadvantages of unstable membrane bubble and low output. The appearance of membrane bubble internal cooling system solves the problem of traditional air ring. One of the biggest advantages is the high output of products.

2) The film bubble runs smoothly to ensure good transparency of the film

3) The film has good opening

4) The tensile strength and tear strength of the film have also been greatly improved.
