How to properly use the plastic film blowing machine system

In the production process, the production of blown film is not only restricted by the bubble, but also the cooling system of the plastic blew film machine. Then, in production and processing, how should we rationally use the cooling system of a small blown film machine?

First, the plastic film blowing machine often needs to cool and shape the blown film in the process of blowing the film. The cooling system of the small film blowing machine includes external cooling and internal cooling. We have to choose the appropriate cooling method for different situations.

Second, the internal cooling of the small blown film machine is to achieve the purpose of cooling through the bubble heat dissipation. This method is relatively unstable, the internal air is relatively non-circulating, and the cooling rate is relatively slow.

Third, the external cooling of the plastic film blowing machine is to release the cooling air through a circular ring along the extrusion direction and the outer surface of the bubble through the cooling ring, thereby generating cold air around the film to achieve external uniform cooling, and at the same time, there is an opening in the cooling ring to discharge hot air to achieve internal air circulation and uniform pressure to ensure the formation of the bubble.

Fourth, the stability and integrity of the plastic blown film cooling system is an important part of ensuring the quality of blown film products! The correct use of the cooling method in the cooling process of small blown film machine can improve the quality of the blown film and improve work efficiency.
