The working principle of PET bottle blowing machine

by:Yosion Machinery     2020-10-25
What bottle blowing machine working principle is: the bottle blowing process is a two-way stretch ( Longitudinal and transverse) Process, in this process, PET chains are arranged two-way stretch, orientation, and, thus increasing the bottle wall mechanical performance, can improve the tensile, tensile, impact strength, and has good air tightness. While stretching helps to improve the strength, but not excessively stretching, to control good stretch blow ratio: radial not more than 3. Five to four. 2, the axial not more than 2. 8 - 3. 1. The bottle preform thickness not more than 4. 5mm。 Bottle blowing is between the glass transition temperature and crystallization temperature, general control between 90 ~ 120 degrees. PET show is within the range of the high elastic state, blow molding, cooling rapidly become transparent bottle after setting. In step method, the temperature is determined by the cooling time length in molding process ( Such as aoki bottle blowing machine) , so be well matched note & ndash; The relationship between the two stations. Tensile & ndash; blow molding process are: , a blow & ndash; Second blow, three action time is very short, but be sure to cooperate well, especially the former two step determines the overall distribution of the material, by the quality of bottle blowing. So to adjust good: stretch the starting time, stretching rate, blow the start and end time, air pressure, blowing air flow, etc, if possible, best can control the temperature of the bottle preform general distribution, bottle preform, both inside and outside wall temperature gradient.
