Analysis of forming bubbles in glass bottles. I firmly believe that all the friends in the glass bottle manufacturing industry have encountered this kind of problem. The formed glass bottles, beverage bottles and wine bottles have bubbles. Today, the editor of the website will take everyone to have a look at this problem.
Glass bottle is a traditional beverage packaging material in China. Glass is a packaging product with a long history. With many kinds of packaging products pouring into the sales market, glassware still occupies a key position in the beverage, which is inseparable from its packaging characteristics that cannot be replaced by other packaging products.
Analysis of the causes of the formation of bubbles in glass bottles such as wine bottles and beverage bottles
1. When the glass raw material blank falls into the parison mould, it can not accurately enter the parison mould, and the friction with the wall of the mould (title: mother of industrial production) is too large, resulting in wrinkles. After the positive air blowing inspection, the wrinkles spread out and become larger, resulting in wrinkles in the glass bottle body.
2. Part of the feeder shears are too large, and some glass bottles have shears after forming.
3. The quality of the raw materials for the initial mold and molding of the glass bottle is poor, the relative density is insufficient, and the air oxidation is too fast after high temperature, resulting in small pits on the surface of the mold, resulting in the unsmooth surface of the formed glass bottle.
4. Too low oil quality of the glass bottle mold will lead to insufficient wetting of the mold, reduced drop rate and too fast change of the material type.
5. The initial mold design concept is not scientific, and the mold core is large or small. After the material drips into the forming mold, it is blowing and the external diffusion is uneven, which will make the glass bottle body appear black spots
6. The uneven dropping rate of the equipment and the improper adjustment of the air nozzle will make the initial mold and mold forming temperature of the glass bottle incompatible, and it is very easy to produce cold spots on the glass bottle body, which will immediately endanger the smoothness.
7. In the industrial furnace (oven), the glass steel material liquid is not clean or the material temperature is not uniform, which will also cause the production rate glass bottle to appear bubbles, small particles and small hemp.
8. Too fast or slow speed of the queue machine bar is caused by uneven glass bottle body and uneven thickness of the bottle wall, resulting in spots.
That is to say, the analysis of bubbles in the forming of wine bottles and glass bottles produced by the website for you. I hope you can be more careful in the production and manufacturing after reading this article.
