Causes Of Leakage And Uneven Wall Thickness Of Glass Bottles

The main cause of leakage in glass bottles

The first is the bottle stopper. The aluminum cap is corroded and embritched. The bottle stopper is not tightened or the range of twist is too tight, so that the sealing of the glass bottle(Learn about other glass bottles​) is over the big bottle stopper and suffers from ground stress.

Second, packaging materials and products are mutually exclusive problem. The product will form a vapor body that reacts with the glass bottle, etching the aluminum cap and causing the cork to loosen, forming water vapor into the diluent product in between. It is the key cause of the problem.

Third, the bottle stopper tightening torque is not unified. Raw pulp, oil aluminum cap and glass bottle mouth only a protruding surface. The compound sealing gasket made of ptfe and butyl rubber sheet metal processed by laser is hard. Because the packaging is planned to be made by craft, different people have different tightening amplitude, resulting in inconsistent sealing effect.

Fourth, the glass bottles have production quality problems. Glass bottles are controlled bottles, semi-mechanical equipment and semi-manual service production and processing, which are harmed by human error and have weak homogeneity.

Causes of uneven wall thickness of glass bottles  

1. The shoulder of the glass bottle;  Some of the shoulder of the glass bottle is thin, not up to the required standard.  The thick wall defect of bottle shoulder is usually caused by excessive temperature of the relative part of the material blank without proper cooling or wetting, or too late in the beginning of positive air blowing inspection and excessive extension of the material blank.  

2. The glass bottle is thin.  This kind of blemish key points to the bottle body of glass bottle namely thin thick part or all do not amount to the thin thick standard that the standard sets.  The reason for this formation is often that the reheating time of the prototype material embryo is too long, and the delay in the beginning of the positive air blowing inspection will also lead to the asymmetry of glass bottle wall thickness.  The wrong operation of its abrasive building coating, abrasive is very dirty, resulting in a large temperature difference between each side of the forming die or forming die refrigeration is not suitable.  

3. Thin bottom for glass bottles;  The bottom of the glass bottle is not up to standard thickness.  The initial mold contact time is too long, or lack of reheating time, the billet temperature is too low, the laminated glass widening is not good;  Too early in the inverted blowing inspection, or too long in the inverted blowing time, the pre-reheat of the bottle is lack;  Too early or too long for positive blow inspection;  Perhaps the timing of the punch pin (mandrel) execution time is not suitable often will be.
