Reasons For Uneven Thickness Of Glass Wine Bottles

A glass wine bottle is a container for wine. If uneven thickness can cause glass bottles to break easily, what is the reason for uneven thickness of glass wine bottles? The following editor will take you to learn more.

The uniform distribution of thickness in glass wine bottles can be said to be one of the ideal overall goals of the molding process, but it is impossible for all glass wine bottles to have uniform thickness. There are always some exceptions. What is the reason for the uneven thickness of glass wine bottles? Today, the editor will take you to understand the reasons.

1. Shoulder of glass wine bottle: Part of the position of the glass wine bottle is very thin, which does not meet the required model standards. The disadvantage of the thick wall tube on the shoulder is mostly due to the fact that the relative part of the raw material embryo is not properly frozen or moistened, resulting in high temperature, or the start time of the positive blow inspection is too long, which leads to excessive stretching and bending of the raw material embryo.

2. Thin glass bottle body: The key to this disadvantage is that the thickness of the glass bottle body is a part of it, or it does not meet the standards of the standard thin-walled model. The reason is that the reheating time of the prototype raw material is usually too long, the start time of the positive air blowing inspection is delayed, the wall thickness of the glass bottle may also be uneven, and the incorrect operation of the mold industrial building coating can cause the mold to be very dirty, the temperature difference in various positions of the forming mold to be particularly large, and the cooling of the forming mold to be improper.

3. Thin bottom of glass wine bottles: The bottom thickness of glass wine bottles does not meet the standard model standards, the initial contact time with the mold is too long or the reheating time is insufficient, the temperature of the preform is too low, and the diffusion of glass containing reinforced rubber is not good; There is a high possibility that the blowing inspection starts early, or the blowing time is too long, the pre weight of the bottle is not hot enough, the positive blowing inspection starts early, or the positive blowing inspection time is too long, or the timing execution time of the needle (spindle) is not appropriate.

What are the factors that affect the smoothness of glass wine bottles?

1. When reinforced glass droplets fall into the initial mold, they cannot enter the initial mold correctly, causing excessive friction with the mold wall and wrinkling. After blowing air for inspection, the wrinkles diffuse and increase, causing the glass drum to wrinkle.

2. The scissor marks on the upper feeding machine are too large, and after the glass bottle is formed, scissor scars appear on the bottle body.

3. The initial mold and molding raw materials of the glass bottle are poor, with insufficient density. After high temperature, it oxidizes too quickly, forming small grooves on the surface of the mold, and forming unevenness on the surface of the formed glass bottle.

4. The low oil quality of the glass bottle mold can lead to insufficient lubrication of the mold, a decrease in drip rate, and rapid material mold changes.

5. Due to the unreasonable design concept of early molds, whether the mold was large or small, the material dropped into the forming mold was blown and diffused unevenly, resulting in black spots on the glass bottle body.

6. Uneven dripping speed of mechanical equipment, improper nozzle adjustment, and inconsistent initial mold forming temperature with the glass bottle can easily cause processing cold spots on the shell of the glass bottle, which can quickly damage the smoothness.

7. When the tempered glass adhesive liquid in industrial kilns is not clean or the mold temperature is uneven, production glass bottles will produce bubbles, small particles, and small clumps.

8. Too fast or too slow speed is caused by uneven glass bottle body, thin bottle wall, different thickness, and color spots.
