Three important factors in the operation of Dalian blow film unit

The application of film blowing machines will become more and more well-known with the development of society. Therefore, we should also know the production cooling method of film blowing machines. Only in this way can it be beneficial for the use of film blowing machines. When carrying out production cooling, we not only need to pay attention to these factors, but also have more things to pay attention to. These factors will all affect film blowing machines, and the production cooling method is also a knowledge, To achieve significant results in the production cooling method of the film blowing machine, it is necessary to learn more knowledge in various aspects.

In order to obtain plastic bag products with controllable quality during the processing of the blow molding machine, it is necessary to control each processing link in place. In general, the processing of plastic blow molding machines includes feeding heating, traction, and control of compressed air edge collection. After blowing air through the air hole on the film head, the air is added to the middle of the circular film, and the film forms a straight line upwards. The size of the plastic bag is controlled by the amount of air blown, and then it is stabilized by a film stabilizer. The thickness is controlled by the host and traction speed, which can be understood. The faster the host speed, the faster the feeding speed, and the thicker the film. On the other hand, traction is the opposite. The faster the pulling, the thinner the film, which is the main link.

How to control the size and pressure of plastic bags during the production process of blow molding machines, and the size and pressure of plastic bags are things that we should understand. These are all things worth our attention. In recent years, under the painful period of adjustment, many blow molding machine manufacturers who have followed the trend and speculated have withdrawn from the market, which has also provided a better market environment for the healthy development of the Chinese blow molding machine industry.

Blow out ratio is one of the key control points in the production process of blow molded films, which refers to the ratio of the diameter of the blown film bubble to the diameter of the pipe ring that has not been blown out. The inflation ratio of the fully biodegradable bag making machine is the lateral expansion ratio of the film, which is actually a transverse stretching of the film. Stretching will have a certain degree of orientation effect on plastic molecules, and the inflation ratio will increase, thereby improving the lateral strength of the film.
