How glass products are produced

Table of Contents

The production process of glass bottles has a history of hundreds of years. In the case of perfume bottles, the main production method of glass bottles is: automatic production line. The main material component is high white material. The raw material of the glass bottle is heated at high temperature to form a bubble-free glass liquid. This is a very complex physical and chemical reaction process, which is carried out in a melting furnace with strict temperature requirements.

Usually the temperature in the melting furnace must be between 1300~1600°C. At first (when the temperature was not high enough) the glass perfume bottles produced were mostly defective. During the melting process, if the temperature inevitably changes, some fine air bubbles will be produced in the molten glass. The standard for judging whether there are bubbles in a glass bottle is generally to see whether the diameter of the bubbles is greater than 1mm. Some manufacturers may have higher standards in order to serve the high-end market of luxury brands. Generally speaking, the more stable the temperature, the better the quality of the glass.

The melting furnace works 24 hours a day; once it stops, the life of the furnace will be greatly reduced, or even damaged.

In fact, there are manual blowing molds and machines in the production process of glass bottles, but now due to the increasing labor costs and the aging of old craftsmen and the loss of skills, glass factories have gradually eliminated the manual blowing process.
